OPINION
¶ 1 After a jury trial, appellant Lando Ahu-mada was convicted of possessing both the narcotic drug cocaine and drug paraphernalia. He was sentenced to substantially mitigated, concurrent prison terms of 2.25 and .75 years. He argues the trial court should have granted his motion to suppress the cocaine found in his pocket because the officer’s search exceeded the scope of the consent Ahumada had given. He also argues the search was unlawful under the “plain-feel” doctrine. Because we conclude the evidence was lawfully seized under that doctrine, we affirm the trial court’s ruling and, in turn, Ahumada’s convictions and sentences.
Factual and Procedural Background
¶ 2 When reviewing the denial of a motion to suppress evidence, we consider only the evidence presented at the suppression hearing, viewing that evidence in the light most favorable to upholding the trial court’s ruling.
State v. Teagle,
¶ 3 South found Ahumada near the slot machines, identified himself, and asked Ahu-mada his name and whether “he had anything illegal on him.” Ahumada said he did not. South then asked Ahumada to empty his pockets, which Ahumada appeared to do. South next asked if he could conduct a “pat down,” to which Ahumada agreed. South felt an object in Ahumada’s right pocket and asked what it was. Ahumada said he did not know, and South reached in and pulled out “two small plastic bindles with a white rocky substance in them.”
¶ 4 The trial court denied Ahumada’s motion to suppress, finding it was “objectively reasonable” for the officer to believe Ahuma-da’s consent to the pat-down included the inside of his pants pockets. The evidence was admitted at trial, Ahumada was found guilty, and this appeal followed his conviction and sentencing.
Discussion
¶ 5 Ahumada argues the trial court abused its discretion when it denied his motion to suppress the evidence found in his pocket. Specifically, he contends the officer exceeded the scope of Ahumada’s consent to a paUdown when he reached into Ahumada’s pocket. When reviewing a trial court’s ruling on a motion to suppress, “we evaluate discretionary issues for an abuse of discretion but review legal and constitutional issues de novo.”
State v. Huerta,
¶ 6 “The Fourth Amendment to the United States Constitution prohibits unreasonable searches and seizures.”
State v. Jones,
Scope of Consent
¶ 7 “The standard for measuring the scope of a suspect’s consent under the Fourth Amendment is that of ‘objective’ reasonableness — what would the typical reasonable person have understood by the exchange between the officer and the suspect?”
Florida v. Jimeno,
¶ 8 Ahumada counters that a pat-down is reasonably understood to involve the passing of an officer’s hands over the outside of a person’s clothing only, commonly to determine whether the person is carrying a weapon. This understanding of a “pat down” is consistent with our Supreme Court’s use of the term — and the limitations on that type of search — in the context of investigatory detentions conducted pursuant to
Terry v. Ohio,
¶ 9
Terry
held that, “[w]hen an officer is justified in believing that the individual whose suspicious behavior he is investigating at close range is armed and presently dangerous to the officer or to others,” the officer may “conduct a carefully limited search of the outer clothing of such person[] in an attempt to discover weapons [that] might be used to assault him.”

at 24, 30,
¶ 10 Although the pat-down search here was not conducted pursuant to
Terry
and therefore was not necessarily subject to the constraints placed upon such searches in that ease and its progeny, we cannot address the scope of consent to a pat-down search without considering the objectively reasonable understandings of its nature, purpose, and extent.
See Jimeno,
¶ 11 Nor, in our view, does South’s previous focus on the contents of Ahumada’s pockets necessarily define the scope of the pat-down later requested. While South’s request that Ahumada empty his pockets undoubtedly conveyed the officer’s interest in their contents, Ahumada could have reasonably understood that request, like the request to conduct a pat-down, as an effort by South to satisfy himself that Ahumada was unarmed. And Ahumada’s strategic decision to empty his pockets only partially, presumably so that he would not expose the cocaine, tends to contradict the theory that he implicitly was consenting to the full search of the inside of his pockets when he agreed to the pat-down moments later.
¶ 12 The trial court cited
Ross
for the proposition that the scope of a search can be defined by the apparent object of the search, a principle also articulated in
Jimeno.
“The scope of a search is generally defined by its expressed object.”
¶ 13 Although no Arizona case has squarely addressed the scope of consent to a
non-Terry
pat-down, cases with similar facts from other jurisdictions are split as to whether a search into a suspect’s pocket exceeds the scope of consent to a pat-down.
Compare United States v. Smith,
¶ 14 Here, the trial court found it “a close question” but concluded the state had proven Ahumada had consented to a search of his pocket. We agree it was a close question but would not necessarily reach the same legal conclusion, given that the state had the burden to show the search was within the scope of consent.
See Valle,
Plain Feel
¶ 15 Under the plain-feel exception to the warrant requirement, which has been
*549
likened to the plain-view exception, an officer may reach into a suspect’s pocket and seize an item of contraband if the officer “lawfully pats down a suspect’s outer clothing and feels an object whose contour or mass makes its identity immediately apparent.”
Minnesota v. Dickerson,
¶ 16 Here, South testified he had seen a surveillance video that showed Ahumada receive something from another man. Ahuma-da then put that item into his pocket as the two looked around, as if to determine whether anyone was watching — behavior South associated from his training and experience with “drug transactions.” Ahumada was then under video surveillance from the time the transaction was recorded until South approached him. South asked Ahumada to empty his pockets, and Ahumada removed everything but the “lump” South felt when he patted him down. When asked by the court if he had “draw[n] any conclusions as to what [he] suspected it might be in the pocket before [he] took the object out,” South responded, “[illegal drugs,” specifically “[cjrack, coke, whatever they can pack up in a rock formation.” He also testified that, in a pat-down, the feel of illegal drugs is “very distinct” and that he is able to detect marijuana, powdered cocaine, and rock-shaped drags by touch.
¶ 17 Although we acknowledge that rock-like items in a pocket are not necessarily contraband, the circumstances surrounding the encounter here supported South’s suspicion that the rock-like substance in Ahuma-da’s pocket was, in all probability, illegal drags. Ahumada argues these facts did not give South probable cause to perform a further search of his pocket and seize the cocaine. He contends South “did not know what was in the pocket; he suspected drugs, but the contents of the pocket were not ‘immediately apparent’ to him.” 3
¶ 18 But probable cause does not require certain knowledge, it requires only facts sufficient to “‘warrant a [person] of reasonable caution in the belief that certain items may be contraband or stolen property or useful as evidence of a crime.”
Brown,
¶ 19 Ahumada points to two cases in which this court has concluded the state did not show the officer had probable cause to seize items felt in a pat-down search,
State v. Valle,
Disposition
¶ 20 We conclude the trial court was legally correct in denying Ahumada’s motion to suppress evidence. Accordingly, we affirm his convictions and sentences.
Notes
. Since then, the Court has not expressly extended the principle to searches of persons and one commentator suggests it ought not do so.

Search and Seizure
§ 8.1(c), at 28 (4th ed.2004) (stating the
"Jimeno
principle ... cannot be literally applied to consent searches of the person”).
But see Safford Unified Sch. Dist. No. 1 v. Redding,
- U.S. -,
. In
Dickerson,
the evidence was suppressed because the officer manipulated the item in the suspect’s pocket before seizing it, thereby subjecting him to an additional search.
. At the suppression hearing, however, defense counsel appeared to concede South had probable cause before reaching into Ahumada’s pocket.
