*463 OPINION OF THE COURT BY
Defendant-appellant Jay Baker Patterson (hereinafter referred to as appellant) was indicted by the grand jury of the third circuit on August 12, 1975, on two counts of ownership or possession of a firearm by a person convicted of a felony. 1 A motion to suppress evidence was filed by counsel for appellant on August 28, 1975. Based on testimony elicited at two evidentiary hearings, the court below denied appellant’s motion. Appellant now brings this interlocutory appeal from the order denying the motion to suppress. The sole question presented is whether appellant voluntarily consented to a warrantless search of his residence by police officers.
The facts of this case are by and large contradictory. However, there is little dispute as to the preliminary setting of the events which are pertinent to this case. During the early *464 evening of July 9, 1975, police оfficers of the Kona District of Hawaii County responded to a report that a shot had been fired into the residence of a Mr. Terrazona. After conducting an examination of the Terrazona home, the officers concluded that the shot had been fired from the direction of appellant’s residence. 2 When that determination was made, several of the officers went over to appellant’s residence. They cautiously entered appellant’s premises as a group, with one police officer driving his vehicle up appellant’s driveway and the other officers following close behind on foot with their weapons drawn and pointed at appellant’s house. Two of the officers on foot were armed with rifles in addition to their service revolvers. Upon reaching the house, the officer who was driving got out of his car and drew his pistol, also pointing it towards appellant’s dwelling. All told, there were four to five armed officers positioned in the yard in front of appellant’s residence.
The events which subsequently took place are in considerable dispute. Therefore, the separate versions of the police and appellant will be set out at some length here. The police officers’ version indicated that upon positioning themselves in front of appellant’s house, the officers asked the occupants to come out of the house, and appellant came out to talk to the officers in the yard. The officers informed appellant of their reason for being there, and appellant denied firing any shots. The police officers indicated that they reholstered their service revolvers while talking to appellant, although two officers were still carrying rifles. Appellant at first agreed to allow the police to search his home, but he then changed his mind and demanded that the police obtain a search warrant. However, appellant nevertheless invited the police officers to come into his living room. Upon receiving this express invitation, three officers entered appellant’s home, and they all sat down in the living room together with appellant and his roommate, one Martinez. The officers did not аt that point *465 conduct any search of the house. The officers testified that throughout this time, appellant was cooperative and never appeared upset or afraid. 3 Shortly thereafter, police Sgt. Ronald Akau arrived at appellant’s home and took charge of the investigation. Sgt. Akau spoke briefly with appellant, at which time appellant again denied any wrongdoing. Akau then asked to use the appellant’s telephone, and he called a deputy prosecuting attorney to ascertain whether there was probable cause to arrest appellant. The attorney advised him that there was no probable cause to arrest as yet, although Akau continued to strongly suspect appellant and Martinez of shooting at Terrazona’s home. Akau did not, however, explicitly inform appellant or Martinez that they were suspects, nor did he advise them of their Miranda rights. During the course of Sgt. Akau’s conversations with appellant, appellant continued to deny that he fired any shots. Appellant further denied having any weapon in the house, and he told Sgt. Akau to go ahead and look through the house if he wished. Akau declined appellant’s oral invitation and consent to a search of the home and told appellant that no search would be conducted without either a sеarch warrant or a written consent to search. Akau stated that at no time did he tell appellant that a search warrant would be forthcoming. However, he did tell appellant that a search warrant might be sought upon further investigation.
Akau then sent Officer Calvin Okahara to obtain a written consent to search form from the police station. Upon Officer Okahara’s return, Sgt. Akau explained the form to appellant in Okahara’s prеsence. 4 Appellant then assured Akau that he wished to consent to a search of the house. Appellant proceeded to fill in “yes” on the consent form, thereby indicating *466 that he consented to a “complete search of [his] premises.” He then signed the form in the appropriate space. Sgt. Akau also signed the form, and it was witnessed by Officer Okahara. Sgt. Akau testified that at no time did any police officer tell appellant that he had to sign the form, nor were any threats or abusive statements ever made by the police officers. A search of the premises thereafter revealed two rifles, both of which were found under appellant’s bed in his bedroom. These rifles, of course, constitute the evidence which appellant seeks to suppress.
Appellant’s version of what took place reflects a considerably different set of circumstаnces. He maintains that he was intimidated and forced into consenting to the search. He testified that when he first saw the police officers, he had no idea why they were coming onto his premises, and he was quite shaken up by the sight of the armed officers positioned outside his home with guns pointed in his direction. His fear was aggravated by the fact that one of the officers threatened to shoot if appellant did not come out in the yard immediаtely to talk to them. Appellant further testified that when the officers first asked his permission to search the house, he asked them if they had a warrant, and they told him that one would be on the way. He then invited the officers into his home, but only in the hope of calming down the situation and to talk things over. Appellant stated that he was frightened by the sight of the armed officers, at least one of whom kept a rifle beside him, sitting in his living room. Appellant maintained that at nо time did he give any oral consent to a search of the house. He testified that after Sgt. Akau had finished *467 making his telephone call to the deputy prosecutor, Akau told appellant that a search warrant was actually being sent over and that appellant should thus sign the written consent form just to “take care” of matters. Appellant stated that at that point he was under the impression that a search warrant had in fact been issued. According to appellant, he was then presented with the consent to search form and was simply told to sign it. He neither read the form nor had its contents read to him, and he signed the form only because he was “mixed up” at the time. 5 He also denied filling in the “yes” box himself. He stated, however, that he thought the form was some kind of a “voluntary search document.”
I
Plainly, the evidence which appellant seeks to suppress was uncovered by the police during the course of a warrant-less search of appellant’s premiáes. Searches conducted without a warrant issued upon probable cause are per se unreasonable unless shown to fall within a specific exception to the warrant requirement of the Fourth Amendment.

Katz v. United States,
It is settled that consent to a warrantless search must be “voluntary” in order to be valid.
State v. Price,
The Fourth and Fourteenth Amendments require that *468 a consent not be coerced, by explicit or implicit means, by implied threat or covert force.
Id., quoting Schneckloth v. Bustamonte, supra, at 228.
Appellant maintains that the consent which he gave to the search of his residence was by no means voluntary. He contends that he was forced into giving his consent by virtue of the coercive atmosphere which pervaded the evening of July 9, 1975. The circuit court, however, disagreed with appellant’s version of the events which transpired at his residence on that night. It thus denied appellant’s motion to suppress. We affirm that decision.
It is well-settled that when the prosecution seeks to rely upon consent to justify the lawfulness of a search, it has the burden of proving by the preponderance of the evidence that the consent was, in fact, freely and voluntarily given.
Bumper v. North Carolina,
The power to judge credibility of witnesses, resolve conflicts in testimony, weigh evidence and draw factual inferences, is vested in the trial court. On appeal all presumptions favor proper exercise of that power, and the trial court’s findings — whether express or implied — must be upheld if supported by substantial evidence.
The role of the reviewing court on this issue is thus quite limited. We adopt the view of the majority of courts and hold
*469
that the findings of a trier of fact regarding the validity of consent to search must be upheld unless “clearly erroneous. ”
7
United States v.McCaleb,
It is difficult for us to conclude that, based on the record presented, the conclusions of the court below were “clearly erroneous.” The record reveals substantial evidence upon which the circuit court could cоnclude that appellant’s consent was in fact voluntarily given. Notwithstanding the fact that the testimony given before the court was highly conflicting, the court implicitly resolved the conflicts in favor of the State’s witnesses.
People v. James, supra.
There was substantial evidence that appellant signed the consent to search form after being carefully and fully advised of his right
*470
to withhold consent.
8
The testimony of the police officers indicated that appellant was never under any duress or force of compulsion at the time he consented to the search. Indeed, the officers’ testimony revealed that appellant was in a cooperative mood and actually encouraged the police to search the house before any consent form was signed by him. In addition, it is clear from the record that this was not the first time that appellant had been involved in a search of his dwelling, for he had previously been subjеcted to such a search in Kona pursuant to a warrant. As stated in
People v. James, supra,
it is evident that appellant was no “newcomer to the law.” Therefore, if the police officers’ version is believed to be true, as it implicitly was by the court below, there is substantial evidence indicating that appellant did not simply acquiesce to the search, but instead gave his consent knowingly, freely and intelligently.

When the findings of the trier of fact on. a motion to suppress are based upon substantial evidence, a reviewing court cannot substitute another possible view of the evidence for that of the trier of fact.
State
v.
Youngblood,

Appellant nevertheless seems to argue that the existence of certain factual circumstances requires a finding that the consent to search was given involuntarily as a matter of law. For example, appellant contends that the arrival of police *471 officers on his premises with weapons drawn and pointed at him is a factor that negates any possibility of voluntary consent. The cases cited by appellant all seem to fall short of supporting his contention. 10 Unlike the officers in those cases, the Kona police never demanded entry to appellant’s home. Also, the entry by the police into appellant’s home was not obtained by force or by show of authority. The court below imрlicitly found that appellant voluntarily allowed the officers into his home without any duress or pressure. Furthermore, appellant was not under arrest or even in custody when he consented to the search. The instant case reflects an absence of the kinds of coercive factors which were present in the cases relied on by appellant. 11
In addition, factors such as the number of officers present, the degree to which they emphasize their authority, and the display of weapons are some of the items comprising the so-called “totality of the circumstances.”
State v. Pinkus,
*472
Ill
Finally, the appellant asserts that whenever a person has denied guilt in the crime under investigation, but nonetheless consents to a search of his premises knowing that contraband will be uncovered by such a search, the consent given under those circumstances cannot be voluntary as a matter of law. However, the finding in the cases cited by appellant that сonsent was involuntary seems to stem from factual circumstances which indicate the presence of duress or coercion. To be sure, none of appellant’s cases explicitly holds that the giving of consent to search with knowledge that contraband will thereby be found will alone require a conclusion that the consent was involuntary as a matter of law.
One of the cases relied upon by appellant,
United States v. Smith,
To hold that consent is involuntary when given with knowledge that contraband will thereby be discovered would have the effect of nullifying every search which turned up incriminating evidence.
People v. James,
supra. Such a result would be absurd. Moreover, it may not be so “incredible” that a defendant would voluntarily consent to a search which he knows would disclose incriminating evidence.
Contra, United States v. Shropshire,
[F]or example, he may wish to appear cooperative in order to throw the police off the scent or at least to lull them into conducting a superficial search; he may believe the evidence is of such a nature or in such a location that it is likely to be overlooked; he may be persuaded that if the evidence is nevertheless discovered he will be successful in explaining its presence or denying any knowledge of it; he may intend to lay the groundwork for ingratiating himself with the prosecuting authorities or the courts; or *474 he may simply be convinced that the game is up and further dissembling is futile.
Affirmed.
Notes
The indictment was brought under HRS § 134-7.
This determination was based on an inspection of the angle of the bullet holes found at the Terrazona house. Appellant’s residence is located approximately 200 to 300 yards southeast of the Terrazona residence.
The testimony of both the police and appellant indicated that appellant even offered coffee to the police officers while they were in appellant’s home.
According to Sgt. Akau, he placed the form on a table between himself and appellant. He then read the contents of the consent form aloud while appellant read along silently. He then asked appellant whether he still wished to consent to the search.
The consеnt form is a standard “Advice of Search and Seizure Rights/Waiver” *466 used by the Hawaii County Police Department. It contains, inter alia, the following information:
You have a constitutional right not to have a search made of your premises without a search warrant.
A request is now being nfade to conduct a search of your premises without a search warrant for any papers, materials or objects that may be connected with any crime being investigated by the police.
You have the right to refuse to consent to such a search.
It is uncontradicted that the consent to search form was signеd at 8:20 p.m., approximately one hour and twenty minutes after the first police unit arrived at appellant’s house.
The same general search warrant requirement is imposed by Art. I, § 5 of the Hawaii State Constitution.
The order denying appellant’s motion to suppress evidence contains the following findings of fact:
1. That as a matter of fact, the Defendant Jay Baker Patterson did knowingly and intelligently and freely give his consent to the police to search his home for firearms;
2. That as a matter of fact, the Defendant Jay Baker Patterson was fully and completely warned by the police of his rights under the Hawaii and United States Constitutions and did freely, knowingly, and intelligently waive those constitutional rights to be free from unreasonable searches and seizures;
3. That as a matter of fact, there is no evidence of and the court finds that the police did not use fraud, trickery or coercion to gаin such waiver of rights by the Defendant Jay Baker Patterson;
4. That as a matter of fact, the search of the premises conducted pursuant to the consent of the Defendant was proper in all respects and does not constitute an unreasonable search and/or seizure;
It should be pointed out that advisement of the right to refuse consent to a search is not required by the Fourth Amendment,
Schneckloth v. Bustamonte, supra,
and whether appellant was so advised is only one factor within the totality of the circumstances to be weighed in determining whether his consent was voluntary.
United States v. Lemon,
For a similar result, see
People v. Johnson,
41 App.Div.2d 997,
Appellant has cited these cases in support of his position:
Harless v. Turner,
The cases which appellant’s counsel directed this court’s attention to in oral argument also do not appear to be persuasive. While it is true that
