    (September 18, 2012)
    Before HULL, MARCUS and HILL, Circuit Judges.
    PER CURIAM:
    Pedro Lorenzo Fuenmayor-Arevalo appeals his convictions and sentences
    for conspiracy to possess with intent to distribute, and actual possession with
    Case: 11-13913     Date Filed: 09/18/2012   Page: 2 of 24
    intent to distribute, five kilograms or more of cocaine while aboard a vessel
    subject to the jurisdiction of the United States, in violation of 46 U.S.C.
    §§ 70503(a)(1) and 70506(a) and (b). After review, we affirm.
    I. BACKGROUND
    A. Arrest and Indictment
    On June 15, 2010, a U.S. Coast Guard vessel spotted a Colombian fishing
    vessel in the international waters of the Caribbean Sea. A Coast Guard team
    boarded the fishing vessel, and a search revealed 70 kilograms of cocaine in a
    hidden compartment in the fish hold of the fishing vessel. Fuenmayor-Arevalo
    and the four other crew members of the fishing vessel were arrested and
    transported to the United States. Fuenmayor-Arevalo’s son-in-law and
    grandnephew were two of these four crew members.
    A grand jury indicted Fuenmayor-Arevalo and the four other crew members
    for conspiracy to possess with intent to distribute, and actual possession with
    intent to distribute, five kilograms or more of cocaine while aboard a vessel
    subject to the jurisdiction of the United States, in violation of 46 U.S.C.
    §§ 70503(a)(1) and 70506(a) and (b).
    B. Plea Hearing
    Fuenmayor-Arevalo indicated that he wished to plead guilty to both counts
    2
    Case: 11-13913     Date Filed: 09/18/2012   Page: 3 of 24
    of the indictment and consented to a joint plea hearing with two of his
    codefendants before a magistrate judge. At the September 20, 2010 hearing, the
    magistrate judge cautioned Fuenmayor-Arevalo that he must plead guilty
    knowingly, voluntarily, and “with a full understanding of the consequences.”
    Through an interpreter, Fuenmayor-Arevalo testified that he was 60 years
    old, had not attended school, was unable to read or write Spanish, and had never
    been treated for any type of mental illness or addiction. He had discussed his plea
    with his attorney, who had offered satisfactory advice and representation. Further,
    Fuenmayor-Arevalo understood the charges against him, including the elements of
    the offenses, that he was subject to a minimum sentence of ten years, and that he
    was giving up his right to a jury trial. Fuenmayor-Arevalo confirmed that no one
    had made any promises or threats in connection with his guilty plea.
    Fuenmayor-Arevalo also admitted to serving as a machinist aboard a boat
    that was hauling more than five kilograms of cocaine. He further admitted that he
    knowingly and willfully entered into a drug-smuggling venture involving five or
    more kilograms of cocaine. He then pled guilty to both counts in the indictment
    without a written plea agreement. Fuenmayor-Arevalo’s counsel then stated that
    he was satisfied that the plea was entered knowingly, voluntarily, and with a full
    understanding of the consequences. The magistrate judge concluded that
    3
    Case: 11-13913     Date Filed: 09/18/2012   Page: 4 of 24
    Fuenmayor-Arevalo was “fully competent and capable of entering an informed
    plea” and that the plea was supported by an independent basis in fact.
    After the September 20, 2010 hearing, the magistrate judge issued a written
    report recommending that Fuenmayor-Arevalo’s guilty plea be accepted as
    “knowledgeable, voluntary, and supported by a factual basis.” Fuenmayor-
    Arevalo did not object to the magistrate judge’s recommendation.
    On October 4, 2010, the district court accepted Fuenmayor-Arevalo’s plea
    and adjudged him guilty on both counts of the indictment.
    C. Motion to Withdraw Guilty Plea
    On November 18, 2010, Fuenmayor-Arevalo moved to withdraw his guilty
    plea. His motion alleged that he was incompetent at the time of the plea.
    Fuenmayor-Arevalo’s motion alleged that he only recently discovered his
    diminished mental capacity, which rendered his plea constitutionally unreliable
    and constituted a previously unknown defense. Fuenmayor-Arevalo’s motion
    stated that he was an uneducated and illiterate Colombian fisherman. His motion
    acknowledged that he appeared to have understood the plea proceedings but
    alleged that the extent of his mental disability “was obscured” because he did not
    speak English. In November 2010, Fuenmayor-Arevalo had undergone a
    psychological examination by neuropsychologist, Dr. Yolanda Leon. According
    4
    Case: 11-13913     Date Filed: 09/18/2012   Page: 5 of 24
    to Fuenmayor-Arevalo, Dr. Leon found that he was borderline mildly mentally
    retarded and possibly suffered from dementia. Although he attached Dr. Leon’s
    curriculum vitae to the motion, Fuenmayor-Arevalo did not submit Dr. Leon’s
    actual report or any other affidavit or evidence in support of the motion.
    In opposition, the government argued that Fuenmayor-Arevalo had not
    provided adequate evidence that he was incompetent at the time he entered his
    plea. To the contrary, the record and evidence established that he was competent
    before, during, and after entering his plea. In support, the government attached
    investigative reports summarizing Fuenmayor-Arevalo’s post-arrest statements,
    which evidenced his rationality and understanding.
    More specifically, according to a post-arrest report prepared after he was
    discovered aboard the fishing boat loaded with 70 kilograms of cocaine,
    Fuenmayor-Arevalo told federal agents, through a Spanish interpreter, that he
    trusted his captain and believed that the boat was simply a fishing vessel. In a
    proffer to the Federal Bureau of Investigation two months later, however,
    Fuenmayor-Arevalo claimed that the captain told everyone what to say and that
    the captain would take responsibility so that everyone else would be set free. In
    the FBI proffer, Fuenmayor-Arevalo admitted that he was given 1.5 million
    Colombian Pesos before departing on the trip and that he was told that the money
    5
    Case: 11-13913    Date Filed: 09/18/2012   Page: 6 of 24
    was for “picking up drugs.” Fuenmayor-Arevalo told the FBI that “he had no
    doubt what he was doing and that he needed the money to get back on his feet.”
    The government also attached reports from FBI interviews, taken in
    November 2010, of three of Fuenmayor-Arevalo’s codefendants, including his
    son-in-law and grandnephew. Fuenmayor-Arevalo’s son-in-law described him as
    intelligent, mentally competent, and a quick learner. Fuenmayor-Arevalo’s son-in-
    law stated that Fuenmayor-Arevalo knew the trip was to transport drugs and
    specifically asked how much money he would receive and where the drugs were to
    be delivered. Similarly, a second codefendant stated that Fuenmayor-Arevalo
    seemed mentally competent, knew right from wrong, and was capable of carrying
    on a normal conversation. Fuenmayor-Arevalo’s grandnephew stated that he was
    teaching Fuenmayor-Arevalo how to read and write and that Fuenmayor-Arevalo
    was “an excellent student.”
    D. Motion for Competency Hearing
    In December 2010, before the district court ruled on the motion to withdraw
    his guilty plea, Fuenmayor-Arevalo filed a written motion for a court
    determination of his competency and again requested to withdraw his guilty plea.
    He claimed that he was legally incompetent because he was unable to assist
    properly in his defense.
    6
    Case: 11-13913   Date Filed: 09/18/2012   Page: 7 of 24
    In support of his motion for a court declaration of incompetency,
    Fuenmayor-Arevalo submitted in camera copies of two psychological examination
    reports. The first report, which resulted from Dr. Leon’s evaluation in November
    2010, concluded that Fuenmayor-Arevalo was mildly mentally retarded, had an IQ
    score of 52, and possibly suffered from dementia affecting his memory and
    problem-solving ability. Dr. Leon opined that Fuenmayor-Arevalo’s “limited
    intellectual ability and apparent neurocognitive impairment” prevented him from
    appreciating the government’s evidence against him and from “providing his
    attorney with any meaningful communications that would allow him to assist in
    his defense.”
    The second report, prepared by Dr. Hector Cases following a neurological
    examination in December 2010, stated that Fuenmayor-Arevalo possibly suffered
    from dementia, but that a brain MRI, brain PET scan, and bloodwork were
    necessary for a definitive diagnosis. However, Dr. Cases still opined that
    Fuenmayor-Arevalo was “not competent to understand the nature and potential
    consequences of the proceedings against him.”
    The government responded that Fuenmayor-Arevalo’s guilty plea should be
    enforced because the psychological evaluation was inconsistent with his conduct
    throughout the proceedings, including his demonstrated ability to logically and
    7
    Case: 11-13913    Date Filed: 09/18/2012     Page: 8 of 24
    reasonably explain the facts of the case.
    After discussing the issue with the parties at a December 7, 2010 hearing,
    the magistrate judge determined that Fuenmayor-Arevalo was entitled to an
    evidentiary hearing and placed him under custodial observation at a federal
    detention center for 30 days.
    E. Motions for Diagnostic Tests and Dr. Luis’s Examination
    In January 2011, Fuenmayor-Arevalo filed a motion requesting no more
    than $6,000 for the three tests—a brain MRI, a brain PET scan, and various
    bloodwork—recommended by Dr. Cases to diagnose dementia.
    Fuenmayor-Arevalo argued that these tests would provide conclusive evidence of
    brain damage or incapacity and were necessary for an adequate defense.
    On February 10, 2011, the magistrate judge denied without prejudice the
    motion for the diagnostic tests. Fuenmayor-Arevalo did not object or otherwise
    challenge the denial of his motion for diagnostic tests.
    On February 11, 2011, the magistrate judge issued an order committing
    Fuenmayor-Arevalo to the custody of the Attorney General for 30 days for a
    competency evaluation under 18 U.S.C. § 4241. During Fuenmayor-Arevalo’s 30
    days at the federal detention center, Dr. Jorge Luis, a forensic psychologist,
    evaluated Fuenmayor-Arevalo and found him competent. In April 2011, Dr. Luis
    8
    Case: 11-13913        Date Filed: 09/18/2012         Page: 9 of 24
    also sent a written report to the court and to Fuenmayor-Arevalo.1
    After receiving Dr. Luis’s report, Fuenmayor-Arevalo renewed his motion
    requesting the diagnostic tests suggested by Dr. Cases. On May 11, 2011, the
    magistrate judge denied the renewed motion because the diagnostic tests were not
    necessary to determine whether Fuenmayor-Arevalo was competent when he pled
    guilty. Fuenmayor-Arevalo did not object or otherwise challenge the magistrate
    judge’s May 11, 2011 order denying this renewed motion for diagnostic tests.
    F. Evidentiary Hearing and Competency Findings
    On June 23, 2011, the magistrate judge conducted an evidentiary hearing
    regarding Fuenmayor-Arevalo’s competency and the validity of his earlier guilty
    plea. At the start of the hearing, Fuenmayor-Arevalo orally renewed his motion
    for the diagnostic tests a second time, and the magistrate judge again denied that
    motion.
    Dr. Leon, a neuropsychologist, testified that she examined
    Fuenmayor-Arevalo in November 2010 and June 2011 to assess his competency.
    Dr. Leon believed that Fuenmayor-Arevalo had been mildly to moderately
    mentally retarded since childhood. Dr. Leon assessed Fuenmayor-Arevalo’s
    1
    Although the district court and the parties apparently received Dr. Luis’s report, the report
    was not docketed in the district court and is not in the record on appeal. Nevertheless, Dr. Luis
    testified about his findings at the competency hearing discussed later.
    9
    Case: 11-13913   Date Filed: 09/18/2012    Page: 10 of 24
    verbal ability IQ score as 52. He showed signs of possible dementia and generally
    displayed the reasoning ability of a six-year-old child. He also appeared “to
    possibly be susceptible to suggestion,” and he would, in an attempt to be
    agreeable, respond affirmatively to basic questions such as, “Is your day going
    well?” Accordingly, Dr. Leon would question Fuenmayor-Arevalo’s assent to any
    proposition unless he articulated it in his own words.
    Dr. Leon also reported that, in one assessment, Fuenmayor-Arevalo was
    presented with brief legal scenarios and his verbal responses were compared to
    those of confirmed incompetent test-takers. Dr. Leon opined that
    Fuenmayor-Arevalo’s low-percentile score showed that he could not adequately
    understand, reason, or appreciate the scenarios. Similarly, with respect to the
    current proceedings, Dr. Leon opined that Fuenmayor-Arevalo was unable to
    articulate the charges against him, whether now or at the time of his plea, and was
    only partially responsive to Dr. Leon’s questions. Regarding
    Fuenmayor-Arevalo’s ability to discuss the proceedings with counsel, Dr. Leon
    opined that Fuenmayor-Arevalo “would have some ability to discuss whatever he
    did capture in terms of attention and retention” but that he could not “engage in a
    meaningful discussion because of his significantly impaired verbal expression
    abilities.”
    10
    Case: 11-13913     Date Filed: 09/18/2012   Page: 11 of 24
    During cross-examination, Dr. Leon testified that she had spent
    approximately three and one half hours interviewing and assessing
    Fuenmayor-Arevalo, which she believed was more than enough time to make a
    valid assessment. In diagnosing Fuenmayor-Arevalo as mentally retarded, Dr.
    Leon relied on his marginal lifestyle, low achievement, apparent inability to learn,
    and his presentation.
    Pat Doherty, the defense attorney for one of Fuenmayor-Arevalo’s
    codefendants, testified that he met with Fuenmayor-Arevalo and found him to be
    incapable of coherently explaining his role in the charged offense or identifying
    the basic function of the judge or the prosecutor. On cross-examination, Doherty
    acknowledged that Fuenmayor-Arevalo told him that there was cocaine on the
    boat and that Fuenmayor-Arevalo knew it was cocaine.
    Dr. Luis, the forensic psychologist from the federal detention center in
    Miami, testified that he had evaluated Fuenmayor-Arevalo during the 30-day,
    court-ordered competency evaluation. During that time, the prison staff reported
    that Fuenmayor-Arevalo had no problem functioning or maintaining his cell. Dr.
    Luis also administered a competency assessment designed to gauge legal
    knowledge and ability. During this competency assessment, Fuenmayor-Arevalo
    (1) correctly identified the charges against him and the basic roles of the judge,
    11
    Case: 11-13913    Date Filed: 09/18/2012    Page: 12 of 24
    prosecutor, and defense attorney, (2) admitted that he was guilty of transporting 70
    kilograms of cocaine, and (3) stated that he faced a potential sentence of nine or
    ten years. Additionally, Fuenmayor-Arevalo was able to provide information
    regarding his personal history and background.
    Dr. Luis found no evidence that Fuenmayor-Arevalo “is impaired by any
    mental disease or defect that would impair his ability to understand the legal
    proceedings.” Dr. Luis also found no evidence of any mental disease or defect
    that would have impaired his ability to consult with his attorney at the time he
    entered his plea. Additionally, Dr. Luis noted that Fuenmayor-Arevalo exhibited
    adaptive functioning in a structured setting because he was able to maintain his
    room and care for himself while he was at the detention center and he was “able to
    inform medical services [at the detention center] that he had been diagnosed with
    hypertension and cholesterol, essentially high cholesterol while he was at the
    [county] jail.”
    During cross-examination, Dr. Luis opined that Fuenmayor-Arevalo’s full
    scale IQ fell in the “very poor” range at 66. However, Dr. Luis testified that
    Fuenmayor-Arevalo apparently functioned well within his own cultural
    environment, as evidenced by his stable family status and long-term occupation.
    Although Fuenmayor-Arevalo performed poorly on some aspects of the
    12
    Case: 11-13913     Date Filed: 09/18/2012    Page: 13 of 24
    competency assessment, Dr. Luis noted that Fuenmayor-Arevalo’s total lack of
    education made it more difficult to administer the tests and interpret the results.
    Further, although Fuenmayor-Arevalo suffered from memory deficits in specific
    areas, Dr. Luis testified that these problems were not significant enough to suggest
    dementia.
    G. Magistrate Judge’s Report on Motions
    In a June 27, 2011 report, the magistrate judge recommended that the
    district court find Fuenmayor-Arevalo competent now and at the time of his plea.
    The magistrate judge expressly credited Dr. Luis’s testimony, which was based on
    Fuenmayor-Arevalo’s rational responses to questions and his 30-day conduct at
    the prison, over Dr. Leon’s testimony based on her limited, post-plea evaluation of
    Fuenmayor-Arevalo. The magistrate judge recommended that the district court
    deny Fuenmayor-Arevalo’s motion to withdraw his guilty plea, which was entered
    knowingly, voluntarily, and with close assistance of counsel.
    On July 26, 2011, Fuenmayor-Arevalo objected to the magistrate judge’s
    report, re-arguing both his earlier motion to withdraw his guilty plea and the
    weight of the evidence regarding his competency. Specifically,
    Fuenmayor-Arevalo argued that his plea was not knowing and voluntary because
    he lacked the ability to understand his rights and available defenses and was
    13
    Case: 11-13913         Date Filed: 09/18/2012        Page: 14 of 24
    susceptible to suggestion. Additionally, he argued that the magistrate judge erred
    in denying his three motions requesting funds for further diagnostic tests.
    After considering the record, the district court adopted the magistrate
    judge’s report, found that Fuenmayor-Arevalo was competent at the time he
    entered his guilty plea, and denied his motion to withdraw his guilty plea.
    H. PSI and Sentencing
    In the presentence investigation report (“PSI”), Fuenmayor-Arevalo was
    held responsible for the 70 kilograms of cocaine found on the boat. He was
    assigned a total offense level of 31 and a criminal history category of I.2 These
    factors established an advisory guidelines range of 108 to 135 months, subject to a
    120-month statutory mandatory minimum sentence under 21 U.S.C.
    § 841(b)(1)(A),3 which narrowed the advisory guidelines range to 120 to 135
    months’ imprisonment. See U.S.S.G. § 5G1.1(c) (providing that the bottom of the
    2
    The PSI assigned a base offense level of 36 under U.S.S.G. § 2D1.1(c) because Fuenmayor-
    Arevalo was responsible for 70 kilograms of cocaine. The PSI applied (1) a two-level reduction
    under § 3E1.1(a) for acceptance of responsibility; (2) a one-level reduction under § 3E1.1(b) for
    timely pleading guilty and assisting authorities with the prosecution of his offense; and (3) a two-
    level reduction under § 2D1.1(b)(16) because Fuenmayor-Arevalo met the criteria for safety-valve
    relief under § 5C1.2(a). Thus, his total offense level was 31. (Although the parties contested the
    applicability of the statutory safety-valve provision, neither party objected to the PSI’s application
    of the two-level reduction under the guidelines safety-valve provision. Because neither party
    objected to any of the guidelines calculations in the PSI or on appeal, we do not address them).
    3
    Under 21 U.S.C. § 841(b)(1)(A), a defendant convicted of a drug offense involving five
    kilograms or more of cocaine is subject to mandatory minimum sentence of 10 years (or 120 months)
    and a maximum sentence of life imprisonment.
    14
    Case: 11-13913     Date Filed: 09/18/2012    Page: 15 of 24
    guidelines range cannot be less than any statutorily required minimum sentence).
    In a PSI addendum, Fuenmayor-Arevalo objected to the PSI’s failure to
    recommend relief from the mandatory minimum sentence pursuant to the
    safety-valve provision of 18 U.S.C. § 3553(f). Fuenmayor-Arevalo also filed a
    separate motion requesting the application of the safety-valve provision.
    However, Fuenmayor-Arevalo did not object to either the factual allegations or
    guidelines calculations in the PSI.
    At sentencing, the district court adopted the factual allegations and
    guidelines calculations set forth in the PSI. The parties then argued their positions
    regarding the applicability of the statutory safety-valve provision in § 3553(f).
    The district court explained that, if the safety-valve applied, the court would likely
    sentence Fuenmayor-Arevalo to no more than 60 months, probably 36 to 48
    months. Nevertheless, although noting that the issue was close, the district court
    concluded that Fuenmayor-Arevalo did not qualify for safety-valve relief.
    Accordingly, the district court calculated a total offense level of 31, a criminal
    history category of I, and an advisory guidelines range of 120 to 135 months’
    imprisonment. The district court imposed the statutory mandatory minimum
    sentence of 120 months.
    II. DISCUSSION
    15
    Case: 11-13913     Date Filed: 09/18/2012    Page: 16 of 24
    A. Competency to Plead Guilty
    Fuenmayor-Arevalo first argues that the district court clearly erred in
    determining that he was competent at the time he entered his guilty plea.
    We review for clear error the district court’s competency determination.
    United States v. Izquierdo, 
    448 F.3d 1269
    , 1276 (11th Cir. 2006). This
    determination is clearly erroneous only if we are “left with a definite and firm
    conviction that a mistake has been committed.” United States v. Rodriguez-Lopez,
    
    363 F.3d 1134
    , 1137 (11th Cir. 2004) (quotation marks omitted). When faced
    with “diametrically opposite expert testimony, a district court does not clearly err
    simply by crediting one opinion over another where other record evidence exists to
    support the conclusion.” Battle v. United States, 
    419 F.3d 1292
    , 1299 (11th Cir.
    2005) (quotation marks omitted). Further, an expert opinion as to competency is
    not binding on the district court if there is reason to doubt it. 
    Izquierdo, 448 F.3d at 1279
    .
    “The due process clause prohibits the trial or guilty plea conviction of a
    person who is mentally incompetent.” Sheley v. Singletary, 
    955 F.2d 1434
    , 1437
    (11th Cir. 1992). The mere presence of mental illness at the time of pleading does
    not necessarily render a defendant incompetent. Rather, the standard for
    determining competency to plead is, in part, whether the defendant has sufficient
    16
    Case: 11-13913     Date Filed: 09/18/2012   Page: 17 of 24
    present ability to consult with his lawyer with a reasonable degree of
    understanding. See 18 U.S.C. § 4241(a); Dusky v. United States, 
    362 U.S. 402
    ,
    402, 
    80 S. Ct. 788
    , 788–89 (1960). Absent evidence of an inability to assist
    counsel, the defendant’s “low intelligence, mental deficiency, bizarre, volatile, or
    irrational behavior, or the use of anti-psychotic drugs is not sufficient to show
    incompetence.” Pardo v. Sec’y, Fla. Dep’t of Corr., 
    587 F.3d 1093
    , 1101 (11th
    Cir. 2009). A defendant must demonstrate his incompetency by a preponderance
    of the evidence. United States v. Bradley, 
    644 F.3d 1213
    , 1268 (11th Cir. 2011).
    Here, we cannot say the district court clearly erred in determining that
    Fuenmayor-Arevalo was competent at the time he entered his guilty plea. At the
    evidentiary hearing, the magistrate judge encountered irreconcilable testimony
    from two experts as to Fuenmayor-Arevalo’s competence. Given this
    irreconcilable testimony, the magistrate judge was free to credit one expert over
    the other. The magistrate judge expressly credited Dr. Luis’s findings, and
    nothing suggests that his testimony was in any way unreliable. Rather, Dr. Luis
    had the benefit of 30 days’ worth of the detention-center staff’s observations of
    Fuenmayor-Arevalo, and Dr. Luis based his findings on those observations and on
    Fuenmayor-Arevalo’s rational responses and understanding of the roles of the
    judge, prosecutor, and defense attorney in his criminal case. Dr. Luis also noted
    17
    Case: 11-13913     Date Filed: 09/18/2012   Page: 18 of 24
    that Fuenmayor-Arevalo had exhibited adaptive functioning in the detention-
    center environment and that he successfully informed medical personnel at the
    county jail about his recently diagnosed hypertension and high cholesterol.
    Furthermore, other evidence in the record supports a finding of competency.
    For example, three of Fuenmayor-Arevalo’s codefendants, including his
    grandnephew and son-in-law, stated that Fuenmayor-Arevalo seemed intelligent
    and was capable of learning. Further, in a proffer to the FBI shortly before the plea
    colloquy, Fuenmayor-Arevalo explained his earlier denial of guilt and detailed his
    role in the drug-smuggling venture. He also admitted to accepting 1.5 million
    Colombian Pesos to transport the drugs because he needed the money to get back
    on his feet. At the evidentiary hearing, one of the codefendant’s attorneys testified
    that Fuenmayor-Arevalo told him that Fuenmayor-Arevalo knew that the fishing
    boat was transporting cocaine. Finally, during the plea colloquy, the magistrate
    judge observed that Fuenmayor-Arevalo appeared to be “fully competent and
    capable of entering an informed plea.” Given all this evidence, the district court
    did not clearly err in finding Fuenmayor-Arevalo competent to plead guilty.
    B. Denial of Diagnostic Tests
    Fuenmayor-Arevalo next argues that the district court erred in denying his
    motions for diagnostic tests for dementia. Fuenmayor-Arevalo asserts that these
    18
    Case: 11-13913      Date Filed: 09/18/2012    Page: 19 of 24
    tests were needed “to secure hard medical evidence to establish incompetency”
    and that the denial of these tests deprived him of his constitutional right to due
    process. See Ake v. Oklahoma, 
    470 U.S. 68
    , 83, 
    105 S. Ct. 1087
    , 1096 (1985)
    (holding that an indigent capital defendant who made a preliminary showing that
    his sanity was likely to be a significant factor at trial had a due-process right of
    access to a competent psychiatrist to conduct an appropriate examination and to
    “assist in evaluation, preparation, and presentation of the defense”).
    We review for abuse of discretion the district court’s denial of a motion for
    expert services, including psychiatric services in cases where competency is at
    issue. United States v. Rinchack, 
    820 F.2d 1557
    , 1563 (11th Cir. 1987). A district
    court should authorize such services if the services are necessary for an adequate
    defense and the defendant lacks the resources to obtain them. Id.; see also 18
    U.S.C. § 3006A(e)(1).
    A district court is not required “to grant an eleventh hour request for Section
    3006A(e) services,” particularly if the delay in making the request is unjustified
    and the services would require a continuance of the hearing. 
    Rinchack, 820 F.2d at 1564
    . Further, if the defendant already has sufficient expert assistance to
    present his competency claim, the district court may deny as unnecessary
    additional psychiatric services. 
    Id. at 1565. 19
                   Case: 11-13913        Date Filed: 09/18/2012        Page: 20 of 24
    Here, Fuenmayor-Arevalo timely objected only to the denial of his third,
    oral motion for diagnostic tests.4 This third motion was made during the
    competency hearing itself and, if granted, would have required a continuance of
    the hearing. The tests thus not only would have caused delay, but also were
    unnecessary because Fuenmayor-Arevalo had already been examined by two
    experts regarding his cognitive ability and his ability to understand legal
    proceedings. One of these experts, Dr. Leon, testified at the evidentiary hearing
    and gave her opinion as to Fuenmayor-Arevalo’s competency—the ultimate issue
    in the case. Accordingly, the district court did not abuse its discretion in denying
    Fuenmayor-Arevalo’s motion for further diagnostic testing.
    C. Denial of Motion to Withdraw Guilty Plea
    Fuenmayor-Arevalo argues that the district court erred in denying his
    motion to withdraw his guilty plea. We review for abuse of discretion the district
    court’s denial of a motion to withdraw a guilty plea. United States v. Buckles, 843
    4
    Before the district court, Fuenmayor-Arevalo did not challenge either the magistrate judge’s
    order denying his first motion for diagnostic tests, filed on January 24, 2011, or the order denying
    his second motion for diagnostic tests, filed on April 27, 2011. Under Federal Rule of Criminal
    Procedure 59(a), a defendant generally must serve and file objections to a magistrate judge’s ruling
    on a non-dispositive matter within 14 days, or he waives any right to review. Fed. R. Crim. P. 59(a);
    see also United States v. Schultz, 
    565 F.3d 1353
    , 1359 (11th Cir. 2009) (“[A]ppellate courts are
    without jurisdiction to hear appeals directly from federal magistrates.”) (internal quotation marks
    omitted). By failing to object to those orders, Fuenmayor-Arevalo waived his right to review of
    those particular orders.
    20
    Case: 11-13913    Date Filed: 09/18/2012   Page: 21 of 
    24 F.2d 469
    , 471 (11th Cir. 1988). Pursuant to Federal Rule of Criminal Procedure
    11(d)(2)(B), the district court may allow a defendant to withdraw his guilty plea if
    he “can show a fair and just reason for requesting the withdrawal.” Fed. R. Crim.
    P. 11(d)(2)(B). In making this assessment, the district court should evaluate the
    “totality of the circumstances surrounding the plea.” 
    Buckles, 843 F.2d at 471–72
    .
    Four factors guide this analysis: (1) whether close assistance of counsel was
    available; (2) whether the plea was knowing and voluntary; (3) whether judicial
    resources will be conserved; and (4) whether the government would be unduly
    prejudiced. 
    Id. at 472. A
    guilty plea is knowing and voluntary if the defendant entered the plea
    without coercion and with the understanding of the nature of the charges and the
    consequences of the plea. United States v. Brown, 
    586 F.3d 1342
    , 1346 (11th Cir.
    2009). We apply a strong presumption that statements made under oath during a
    plea colloquy are truthful. United States v. Medlock, 
    12 F.3d 185
    , 187 (11th Cir.
    1994). Consequently, the defendant bears a heavy burden to show a statement
    made under oath at a plea colloquy was false. United States v. Rogers, 
    848 F.2d 166
    , 168 (11th Cir. 1988). Further, a defendant seeking to set aside a guilty plea
    “must at the very least show that correct information would have made a
    difference in his decision to plead guilty.” United States v. Schubert, 
    728 F.2d 21
                   Case: 11-13913        Date Filed: 09/18/2012       Page: 22 of 24
    1364, 1365 (11th Cir. 1984).
    Here, the district court did not abuse its discretion in denying Fuenmayor-
    Arevalo’s motion to withdraw his guilty plea because the record shows that
    Fuenmayor-Arevalo’s plea was knowing, voluntary, and entered with close
    assistance of counsel. At the plea colloquy, Fuenmayor-Arevalo confirmed that he
    had discussed his plea with his counsel and was satisfied with counsel’s advice
    and performance. Notably, although Fuenmayor-Arevalo argues that a defendant
    with a severe mental handicap is likely incapable of comprehending legal advice,
    he does not argue that he actually failed to comprehend his counsel’s advice.
    Regarding the “knowing and voluntary” requirement, the magistrate judge
    expressly cautioned Fuenmayor-Arevalo that his plea must be entered into
    knowingly, voluntarily, and “with a full understanding of the consequences.”
    Before offering his guilty plea, Fuenmayor-Arevalo confirmed that he understood
    the charges against him, that he was subject to a minimum sentence of ten years,
    that he was giving up his right to a jury trial, and that no one had made any
    promises or threats in connection with his guilty plea.5 Given the totality of the
    5
    Fuenmayor-Arevalo’s argument that the post-plea discovery of a defense based on
    diminished capacity independently constituted a fair and just reason for withdrawal also fails.
    Fuenmayor-Arevalo did not claim or offer any evidence below, through either testimony or affidavit,
    that he would not have pled guilty had he been aware of this defense.
    22
    Case: 11-13913        Date Filed: 09/18/2012       Page: 23 of 24
    circumstances, including Fuenmayor-Arevalo’s testimony at the plea hearing that
    his plea was knowing and voluntary, we cannot conclude that the district court
    abused its discretion by refusing to allow Fuenmayor-Arevalo to withdraw his
    plea.
    D. Denial of Safety-Valve Relief
    Lastly, Fuenmayor-Arevalo argues that the district court erred in ruling that
    he was ineligible for safety-valve relief under 18 U.S.C. § 3553(f) because he was
    convicted for maritime drug law offenses under 46 U.S.C. §§ 70503 and 70506
    that are not specified in the safety-valve statute.6 However, Fuenmayor-Arevalo’s
    argument is foreclosed by our recent precedent in United States v. Pertuz-Pertuz,
    
    679 F.3d 1327
    (11th Cir. 2012). In Pertuz-Pertuz—which involved an appeal by
    one of Fuenmayor-Arevalo’s codefendants convicted of the same maritime drug
    law offenses as Fuenmayor-Arevalo—we held that “the plain text of the statutes
    shows that [maritime drug law] convictions under Title 46 of the U.S. Code . . .
    entitle a defendant to no safety-valve sentencing relief.” 
    Id. at 1329. 6
            Under 18 U.S.C. § 3553(f), the sentencing court may sentence a defendant convicted under
    21 U.S.C. §§ 841, 844, 846, 960, or 963 without regard to the statutory mandatory minimum
    sentence if: (1) the defendant does not have more than one criminal history point, (2) the defendant
    did not use violence, threaten violence, or possess a dangerous weapon in connection with the
    offense, (3) the offense did not result in death or serious bodily injury to any person, (4) the
    defendant was not an organizer, leader, manager, or supervisor of others in the offense, and (5) the
    defendant has truthfully provided to the Government all information and evidence the defendant has
    concerning the offense.
    23
    Case: 11-13913   Date Filed: 09/18/2012   Page: 24 of 24
    Accordingly, we affirm Fuenmayor-Arevalo’s convictions and sentences.
    AFFIRMED.
