Maikel Suarez Plasencia ("Suarez") appeals his convictions and fifty-one-month concurrent sentences for encouraging and inducing aliens to enter the United States, in violation of 8 U.S.C. § 1324 (a)(1)(A)(iv), (v)(II). He contends that his convictions were based on evidence obtained from an unconstitutional search of his global positioning system ("GPS"), which linked him to the illegal entry of Cuban migrants, and that his sentence reflects an obstruction-of-justice enhancement applied contrary to his due process rights and against the merits. See U.S.S.G. § 3C1.1. After careful review, we affirm Suarez's convictions and sentence.

I.

On the morning of September 6, 2015, twenty-eight Cuban migrants were found on Loggerhead Key, Florida. Later that day, Suarez's boat broke down on Garden Key, an island three miles east of Loggerhead Key and seventy miles west of Key West. A park ranger, David Fuellner, responded to a report of Suarez's beached boat and located Suarez and the boat. 1 Fuellner asked Suarez for permission to search his boat, and Suarez consented orally and by signing a consent form. 2 The signed form authorized Fuellner to perform a "complete" search of the vessel and to seize its contents for any "legitimate law enforcement purpose." Suarez then took a ferry to Key West to summon help with fixing his boat.

Fuellner conducted the search the next day and found a GPS which, once plugged into the boat's power source and turned on, showed a waypoint indicating that the boat had been just off of Cuba's shore on *1340 September 5, 2015. 3 Fuellner then powered off the GPS, seized it, and entered it into evidence. Later analysis of the GPS, performed by a Coast Guard analyst, revealed that Suarez left Key West around 1:30am on September 5, arrived off the coast of Cuba at about 4:30pm that day, and then reached the vicinity of Loggerhead and Garden Keys in the early morning of September 6. The trip from Cuba to the United States took about ten hours. No warrant was obtained for Fuellner's search or for this analysis.

Department of Homeland Security ("DHS") agents interviewed Suarez on September 8. Suarez claimed that he had taken his boat on a spear-fishing trip from Key West to the Dry Tortugas 4 and that he spent a night on the vessel. He denied knowledge of a migrant landing in the area. Months later, DHS agents again interviewed Suarez. When they confronted Suarez with the GPS evidence linking him to the Cuban shore, he claimed that the agents had mixed up his GPS with someone else's. However, Suarez admitted that his wife and two of his children were among the migrants who landed on September 6, 2015.

On March 11, 2016, a federal grand jury sitting in the Southern District of Florida returned a twenty-eight-count indictment against Suarez, charging him with alien smuggling, in violation of 8 U.S.C. § 1324 (a)(1)(A)(iv), (v)(II). Suarez filed a motion on June 8, 2016 to suppress the GPS evidence. The District Court denied the motion on two grounds. First, it held that by consenting to a search of his vessel without limitation, Suarez consented to a search of his GPS found onboard. Next, and in the alternative, the Court held that Suarez had abandoned the boat and its contents by leaving it on a public shore for "three to four days" before returning to fix it.

Suarez's case continued on to a jury trial, where Suarez presented as witnesses eight of the Cuban migrants found on September 6, 2015. The migrants testified generally that a "raft" with a single engine brought them from Cuba to the United States, that the trip took two nights and one day, that the raft was destroyed or lost, and that they waded to the United States shore from between fifteen and seventy-five feet out in the ocean. All of the migrant witnesses denied that Suarez assisted their journey in any way. The Government's witnesses testified that no raft, or debris from a destroyed raft, was found and that the ocean's depth even fifteen feet from the shore at which the migrants claimed to have landed would have made wading impossible. The Government also presented testimony that the migrants did not appear hungry, dehydrated, disheveled, or wet-conditions typical of migrants who come from Cuba to the United States by raft. The jury found Suarez guilty of all twenty-eight counts of alien smuggling.

A presentence investigation report ("PSI") of Suarez was then issued. It set the Guidelines range of Suarez's sentence at thirty-three to forty-one months, which accounted for a two-point reckless-endangerment enhancement under U.S.S.G. § 2L1.1(b)(6). The PSI did not recommend a U.S.S.G. § 3C1.1 enhancement for obstruction of justice, stating, "The probation officer has no information indicating the defendant impeded or obstructed justice."

The Government did not object to the PSI for failing to recommend a sentencing *1341 enhancement for obstruction of justice, but it filed notice of its intent to seek an upward variance in Suarez's sentence due in part to the "full day's worth of conflicting, sworn testimony" Suarez presented at trial. Suarez did not respond to the Government's notice, citing a lack of time to do so as the reason.

At sentencing, the District Court applied U.S.S.G. § 2L1.1(b)(6)'s reckless-endangerment enhancement and then, sua sponte , added two more points to Suarez's total offense level under U.S.S.G. § 3C1.1 for knowingly suborning perjury at trial. The Court noted that Suarez knew from his counsel's opening statement that numerous witnesses would lie on his behalf but Suarez nonetheless allowed them to testify. 5 This obstruction-of-justice enhancement increased the Guidelines range of Suarez's sentence to forty-one to fifty-one months. After relaying its decision to impose the enhancement, the Court stated that it "assume[s] that [defense counsel] makes an objection to the Court's analysis." Defense counsel confirmed that he objected, and the Court stated,

So the record is clear. Defense counsel ... has made a valid objection to all of this and objects to the Court's finding and he's fully protected to raise this on appeal. I think that protects the defendant. Do you have anything else? That's the finding.

The Court then heard arguments from the Government and defense counsel about whether the Court should vary from the applicable Guidelines range. The Government requested that Suarez receive sixty months' imprisonment, citing the seriousness of Suarez's offenses and the disrespect to the court that he promoted by presenting false testimony from numerous witnesses. Defense counsel then argued that Suarez deserved only fifteen months' imprisonment because, namely, the migrants Suarez smuggled into the United States were his friends and family and he did not bring them over for profit. Defense counsel made no argument regarding Suarez's subornation of perjury. The Court then denied the Government's request for an upward variance and imposed a sentence of fifty-one months' imprisonment and three years' supervised release. Suarez appealed his convictions and sentence.

On appeal, Suarez first argues that the District Court erred in denying his motion to suppress evidence recovered from the search of his GPS. He contends that the consent he provided to Fuellner did not include consent to search his GPS and that he did not abandon his boat. 6 Next, Suarez makes two challenges to the District Court's decision to apply U.S.S.G. § 3C1.1's two-point obstruction-of-justice enhancement. First, he asserts that the Court violated his due process rights by applying the enhancement sua sponte , without offering him prior notice or an opportunity to argue against the enhancement. Second, he claims that the Court erred on the merits because he did not knowingly present perjured testimony. We start with the District Court's denial of Suarez's motion to suppress.

*1342 II.

When considering a district court's ruling on a motion to suppress, we review factual findings for clear error and application of law to the facts de novo . United States v. Ramos , 12 F.3d 1019 , 1022 (11th Cir. 1994). Clear error lies only where the record leaves us "with the definite and firm conviction that a mistake has been committed." United States v. White , 335 F.3d 1314 , 1319 (11th Cir. 2003) (internal quotation marks omitted). Moreover, we construe all facts in the light most favorable to the party who prevailed below. United States v. Bervaldi , 226 F.3d 1256 , 1262 (11th Cir. 2000).

"The Fourth Amendment protects the people against 'unreasonable' searches and seizures. A consensual search is manifestly reasonable so long as it remains within the scope of the consent." United States v. Martinez , 949 F.2d 1117 , 1119 (11th Cir. 1992). Whether limitations were placed on the scope of consent, and whether the search conformed to those limitations, is a question of fact determined by the totality of the circumstances. United States v. Blake , 888 F.2d 795 , 798 (11th Cir. 1989). The Government bears the burden of showing that its search was conducted within the scope of the consent received. Id. at 799-800 . "When an individual gives a general statement of consent without express limitations," the scope "is constrained by the bounds of reasonableness: what a [law enforcement] officer could reasonably interpret the consent to encompass." Martinez , 949 F.2d at 1119 .

Our decision in United States v. Street , a case analogous to Suarez's, is instructive. See 472 F.3d 1298 (11th Cir. 2006). There, the defendant consented to a "complete search" of his residence and to seizure of "any items" related to a string of recent bank robberies. Id. at 1308 . Law enforcement found a police radio on a bedroom floor, turned it on, and noticed that it was tuned to a radio zone covering where a robbery had occurred earlier. Id. at 1303 . Because the radio was in plain view and the defendant did not limit the search, we concluded that law enforcement could reasonably believe that the radio was within the scope of the consent provided. Id. at 1308-09 .

Here, via signed consent form, Suarez consented to a "complete" search of his boat and to seizure of its contents for any "legitimate law enforcement purpose." He did not limit the scope of his consent in any way. Cf. United States v. Rich , 992 F.2d 502 , 507 (5th Cir. 1993) ("[The defendant], knowing the contents of [his] vehicle and its various containers at the time he gave his consent, had the responsibility to limit the scope of the consent if he deemed it necessary to do so."). Fuellner found the GPS in one of the boat's storage compartments, lying beneath some other items. Suarez's consent clearly covered the compartment where the GPS was found, despite Suarez's argument to the contrary. See United States v. Strickland , 902 F.2d 937 , 942 (11th Cir. 1990) (holding that an officer's search of a spare-tire compartment was within the scope of the defendant's consent to a search of his "entire vehicle").

Suarez further argues that Fuellner exceeded the scope of Suarez's consent by powering up the GPS, which was off when Fuellner found it. Street , however, guides the other way. See 472 F.3d at 1308-09 . Moreover, in determining the scope of a search, we consider "what the parties knew at the time to be the object of the search." Martinez , 949 F.2d at 1119 . Suarez's boat was beached seventy miles from Key West's shore. A reasonable person would understand that giving "complete" consent to a search of his boat, in *1343 this context, would include consenting to the search of a GPS on board that could indicate where the boat had been and shed light on why it is beached so far out in the ocean. This is especially so given that the consent form indicated that law enforcement was looking generally for items that could be used for any legitimate law enforcement purpose. Conversely, an officer receiving unbounded consent in this situation could reasonably believe that the consent covered a search of the GPS. Fuellner therefore did not violate Suarez's Fourth Amendment rights by searching the GPS. And, for the same reasons, nor did the Coast Guard analyst in performing a forensic analysis of the GPS. Accordingly, the District Court did not err in denying Suarez's motion to suppress.

III.

Suarez next argues that the District Court's application of U.S.S.G. § 3C1.1's two-point enhancement was both in violation of his due process rights and incorrect on the merits. When reviewing a district court's decision to apply an enhancement under § 3C1.1, we review factual findings for clear error and the district court's application of the Guidelines to those facts de novo . United States v. Bradberry , 466 F.3d 1249 , 1253 (11th Cir. 2006). In reviewing the district court's findings of fact, we provide "substantial deference" to the court's credibility determinations at sentencing. United States v. Clay , 483 F.3d 739 , 744 (11th Cir. 2007).

A.

Suarez contends that the District Court violated his due process rights by imposing the § 3C1.1 enhancement sua sponte , without providing him adequate notice or an opportunity to be heard on the issue. We disagree.

Due process requires that a criminal defendant have adequate notice of, and an opportunity to contest, the facts used to support his criminal penalty. United States v. Jules , 595 F.3d 1239 , 1243 (11th Cir. 2010). But "sentencing procedures are not required to be as exacting as those at trial." Id. The defendant's primary due process interest at sentencing is the "right not to be sentenced on the basis of invalid premises or inaccurate information." See id. Hence, the degree of due process protection required at sentencing is only that which is necessary "to ensure that the district court is sufficiently informed to enable it to exercise its sentencing discretion in an enlightened manner." United States v. Stephens , 699 F.2d 534 , 537 (11th Cir. 1983).

Federal Rule of Criminal Procedure 32 governs, inter alia , the issuance of PSIs. Rule 32(d) requires that a PSI "identify all applicable guidelines" and "any factor relevant to ... the appropriate kind of sentence." But district courts are not bound by the facts and recommendations set forth in a PSI; they may choose not to adopt the facts as recited in the report or not to apply the Guidelines in the proposed manner. United States v. Jones , 899 F.2d 1097 , 1102 (11th Cir. 1990), overruled in part on other grounds , United States v. Morrill , 984 F.2d 1136 (11th Cir. 1993) (en banc); see United States v. Aguilar-Ibarra , 740 F.3d 587 , 591 (11th Cir. 2014) (noting that district courts have an obligation independent of the PSI to correctly calculate the defendant's Guidelines range). It follows that, with proper notice, a court may apply Guidelines enhancements not identified in the PSI. 7

*1344 Here, defense counsel's opening statement indicated that the migrant witnesses would deny Suarez's involvement in their illegal entry into the United States. Then, Suarez sat idly as the witnesses told a similar story contradicting the record. This put Suarez on notice that the witnesses' apparently false testimony, and his own inaction, might later be cited by the Government or the Court as a reason for lengthening his sentence. Indeed, before Suarez's sentencing hearing, the Government provided notice that it intended to seek an upward variance in part because of the witnesses' perjured testimony. Suarez thus cannot claim that he lacked adequate notice of the conduct underlying the Court's sua sponte decision to apply § 3C1.1's obstruction-of-justice enhancement.

The Guidelines, moreover, "define specific and finite factors warranting the application of an upward or downward adjustment to a defendant's otherwise applicable sentencing range." United States v. Canada , 960 F.2d 263 , 266 (1st Cir. 1992). Therefore, when, as here, the circumstances afford a defendant notice that he engaged in conduct that may result in the application of a Guidelines enhancement, the court need not provide additional notice of its intention to apply the enhancement sua sponte -the Guidelines themselves provide adequate notice. 8

Further supporting this conclusion are the Supreme Court's decisions in Burns v. United States , 501 U.S. 129 , 111 S.Ct. 2182 , 115 L.Ed.2d 123 (1991), and Irizarry v. United States , 553 U.S. 708 , 128 S.Ct. 2198 , 171 L.Ed.2d 28 (2008). In Burns , the Court held that before a district court may issue an upward departure from the Guidelines, notice must be given in the PSI, in a prehearing submission by the Government, or by the district court itself. Burns , 501 U.S. at 138 , 111 S.Ct. at 2187 . Unlike with enhancements, "the Guidelines place essentially no limit on the number of potential factors that may warrant a departure." Id. at 136 , 111 S.Ct. at 2186 . Hence, notice is more important for defendants to prepare an argument against a departure than to prepare one against an enhancement.

In Irizarry , the Court then abrogated its holding in Burns by deciding that notice, although necessary for a court to issue an upward departure, 9 is not necessary *1345 for a court to issue an upward variance . 553 U.S. at 716 , 128 S.Ct. at 2203 . It noted that because United States v. Booker , 543 U.S. 220 , 125 S.Ct. 738 , 160 L.Ed.2d 621 (2005), rendered the Guidelines advisory, there was no longer an "expectation subject to due process protection ... that a criminal defendant would receive a sentence within the presumptively applicable Guidelines range." Irizarry , 553 U.S. at 713 , 128 S.Ct. at 2202 . Given that defendants are not entitled to notice of variances-and that Guidelines enhancements, unlike departures, are finite and specific-Suarez, who had notice of § 3C1.1 and of his witnesses' conduct at trial, was not denied due process when the District Court applied § 3C1.1 sua sponte .

Suarez contends that a new sentencing hearing is nonetheless warranted because the District Court failed to allow his counsel to comment on the § 3C1.1 enhancement. See United States v. Mylor , 971 F.2d 706 , 707 (11th Cir. 1992) (holding that the district court erred by refusing to hear argument by the defense concerning a Guidelines enhancement). 10 Although the District Court noticed a defense objection to the § 3C1.1 enhancement without explicitly stating the basis of the objection, it did ask counsel whether there was "anything else" regarding the enhancements it applied. The Court then heard further argument from both parties regarding whether to deviate from the applicable Guidelines range in imposing Suarez's sentence. The Government argued for an upward variance in part because of the defense witnesses' false testimony-even stating that the District Court "succinctly summed up" the basis for its argument when imposing the § 3C1.1 enhancement. In his response, however, defense counsel did not attempt to counter the Government's argument or push back on the District Court's conclusion that Suarez suborned perjury. The Court did not refuse to hear argument from counsel related to Suarez obstructing justice; rather, counsel failed to argue the point. A new sentencing hearing is therefore not warranted. 11

B.

Suarez also contends that the District Court clearly erred in concluding that he suborned perjury and thus in applying § 3C1.1. We find no clear error.

Section 3C1.1 applies if "the defendant willfully obstructed or impeded, or attempted to obstruct or impede, the administration of justice with respect to the investigation, *1346 prosecution, or sentencing of the instant offense of conviction." Covered conduct includes "committing, suborning, or attempting to suborn perjury." U.S.S.G. § 3C1.1 cmt. n.4(B). Under § 3C1.1, "the defendant is accountable for the defendant's own conduct and for conduct that the defendant aided or abetted, counseled, commanded, induced, procured, or willfully caused." U.S.S.G. § 3C1.1 cmt. n.9; Bradberry , 466 F.3d at 1254 .

Knowingly procuring another to commit perjury constitutes subornation of perjury. Bradberry , 466 F.3d at 1254 . Perjury, for purposes of § 3C1.1, is defined as giving "false testimony concerning a material matter with the willful intent to provide false testimony, rather than as a result of confusion, mistake, or faulty memory." Id. (quoting United States v. Singh , 291 F.3d 756 , 763 (11th Cir. 2002) ). The Guidelines define material evidence as "evidence ... that, if believed, would tend to influence or affect the issue under determination." U.S.S.G. § 3C1.1 cmt. n.6. Thus § 3C1.1's enhancement applies where a defendant knowingly calls a witness to testify on his behalf to produce false testimony tending to influence or affect the jury's verdict. See Bradberry , 466 F.3d at 1254 .

Suarez became aware of the migrant witnesses' potential testimony no later than during his counsel's opening argument, when counsel stated that the witnesses would deny that Suarez aided their entry into the United States in any way. Then, spanning over more than a full day of trial, Suarez watched as each of the eight witnesses relayed a similar story denying his involvement and contradicting portions of the record. This testimony, moreover, served as Suarez's primary evidence of innocence. Under these circumstances, the District Court, which receives wide latitude in determining the credibility of evidence, Clay , 483 F.3d at 744 , did not clearly err in concluding that Suarez knowingly suborned perjury, cf. Bradberry , 466 F.3d at 1254 .

Finally, Suarez argues that because the Court applied § 3C1.1 sua sponte and without hearing from the Government, the Government could not have met its burden of proving the enhancement's applicability by a preponderance of the evidence. See United States v. Ndiaye , 434 F.3d 1270 , 1300 (11th Cir. 2006) ("The Government has the burden of proving the applicability of Guidelines that enhance a defendant's offense level.") But a "district court's factual findings for purposes of sentencing may be based on, among other things, evidence heard during trial." Id. (quoting United States v. Polar , 369 F.3d 1248 , 1255 (11th Cir. 2004) ). The Government presented testimony and other evidence at trial exposing the defense witnesses' perjury, and the District Court did not clearly err in crediting this evidence and determining that § 3C1.1 applied. See Clay , 483 F.3d at 744 .

IV.

For the reasons discussed above, we affirm Suarez's convictions and sentence.

AFFIRMED.
