Robert Michenfelder, a maximum security prisoner, appeals an adverse judgment in his § 1983 action against Nevada state prison officials for conducting strip searches and otherwise exposing unclothed male inmates to view by female guards in the course of their duties in violation of the *330 fourth and eighth amendments. The district court found the searches reasonable, given the prison’s legitimate security concerns and female prison employees’ rights to equal employment opportunities. It also found that the prison’s taser gun policy did not violate the Eighth Amendment. We affirm.
BACKGROUND
When this action commenced Michenfelder was an inmate in the Nevada State Prison’s (NSP) Unit 7, the maximum security unit for the state’s 40 most dangerous prisoners. Defendant Sumner was then warden of the NSP and is now Director of the Nevada Department of Prisons. Other named defendants are correctional officers and prison administrators at NSP.
Strip searches are conducted every time a Unit Seven inmate leaves or returns to the unit, as well as after movement under escort within the unit, such as for sick call, recreation, disciplinary hearings, and visits. The strip searches complained of here include visual body cavity searches, but not physical contact searches. They are conducted at the end of the tier’s hallway, in front of a barred gate behind which the guards conducting the searches stand (in an area known as the “sally port”). The searches are visible to the tier’s other prisoners whose cell doors open onto the corridor, and, through a small window, to guards controlling the cell doors from the “lock box” located in the main corridor outside the tier. The searches also can be observed indirectly by officers in the “control bubble”, a room with video screens for monitoring activity on the tiers by means of video cameras located at either end of the hallways. Female officers are permitted to work in the control bubble, at the lock box, and any other position available to a correctional officer (including shower duty). They do not conduct strip searches except in severe emergencies.
Prison regulations allow officers at NSP to carry “taser” guns. The taser operates by firing a tiny dart, attached to the gun with wires, into the prisoner, and by administering a low amperage, high voltage electrical shock which temporarily incapacitates the prisoner.
See People v. Heffner,
PROCEEDINGS BELOW
Michenfelder commenced this § 1983 action on July 5,1984. The complaint seeks a declaratory judgment that the frequent searches, conducted where other inmates and female correctional officers could observe him naked and subject to threatened use of the taser, violated Michenfelder’s constitutional rights. He simultaneously filed a separate motion for a preliminary injunction prohibiting prison officials from strip searching him in view of female officers and and other inmates, from conducting searches before and after transport to certain activities within Unit Seven when he would be under escort at all times, and from using the taser at any time.
The magistrate consolidated the hearing of the preliminary injunction motion with the trial of the action by minute order dated August 27, 1984. Over Michenfelder’s objections the district court affirmed the consolidation by order filed September 19, 1984. The trial was held on October 3 and October 24, 1984. On March 29, 1985 the magistrate recommended denial of the injunction and grant of judgment for the defendants. She found that the location and frequency of the searches was a reasonable response to a legitimate security interest within the prison, and that using female correctional officers for tasks that offer occasional views of nude prisoners is a good faith attempt to comply with the officers’ equal employment opportunities. The magistrate further found that use of tasers was a reasonable method of ensuring compliance with the strip search policy, and thus was not cruel and unusual punishment.

STANDARD OF REVIEW
We review the trial court’s findings of fact for clear error.
United States v. McConney,
DISCUSSION
“[Cjonvicted prisoners do not forfeit all constitutional protections by reason of their conviction and confinement in prison.”
Bell v. Wolfish,
In applying the
Turner v. Safley
test we must accord great deference to prison officials’ assessments of their interests: “Prison administration is ... a task that has been committed to the responsibility of [the legislative and executive branches], and separation of powers concerns counsel a policy of judicial restraint. Where a state penal system is involved, federal courts have, as we indicated in
[Procunier
v.]

*332 I. FREQUENCY AND MANNER OF CONDUCTING STRIP SEARCHES
Michenfelder contends that NSP’s strip search policy, which calls for visual body cavity searches whenever an inmate leaves or returns to the unit, as well as when he travels under escort within the unit — including when leaving to or returning from sick call, recreation, disciplinary hearings, and visits — is constitutionally infirm. The district court deferred to the prison officials’ judgment regarding the searches’ necessity, finding Michenfelder failed to show the searches were an exaggerated or excessive means of providing needed security.
Michenfelder,
The fourth amendment guarantees “[t]he right of the people to be secure ... against unreasonable searches and seizures.” This right extends to incarcerated prisoners; however, the reasonableness of a particular search is determined by reference to the prison context. In
Bell v. Wolfish,
“The test of reasonableness under the Fourth Amendment is not capable of precise definition or mechanical application. In each case it requires a balancing of the need for the particular search against the invasion of personal rights that the search entails. Courts must consider the scope of the particular intrusion, the manner in which it is conducted, the justification for initiating it, and the place in which it is conducted.”
Id.
at 559,
Scope and manner.
The searches are conducted on convicted prisoners in NSP’s most restrictive unit, and are visual only, involving no touching.
See Rickman v. Avaniti,
The frequency of strip searches in Unit Seven appears, from this record, to be very high. Prisoners are searched both coming and leaving their cells, even when traveling only within the unit while under escort and in chains at all times. However, so long as
*333
a prisoner is presented with the opportunity to obtain contraband or a weapon while outside of his cell, a visual strip search has a legitimate penological purpose.
Turner v. Safley,
Justification. The fact that Unit 7 houses the state’s most difficult prisoners gives rise to a legitimate governmental security interest in procedures that might be unreasonable elsewhere. In addition, testimony and physical evidence before the district court substantiated several incidents in which contraband and homemade weapons were confiscated from Unit Seven inmates. Though Shift Lieutenant Koon testified that no strip search in Unit Seven had produced a hidden weapon, he also testified that the policy was “the only thing that has prevented that from happening.”
Place.
Michenfelder argues that strip searches should be conducted within the privacy of prisoners’ cells rather than out in the hallway, and says the practice’s irrationality is highlighted by the fact that visual strip searches in other units — and sometimes within Unit Seven — are still conducted through closed cell doors. The district court was persuaded by the State’s position that officers are placed at a “dangerous disadvantage” when required to conduct the search through the solid cell door or enter a cell to enforce compliance, and that alternative sites are unavailable outside the cells that were more private than the hallway.
Michenfelder,
Michenfelder’s argument is not merit-less. In
Rickman
the fact that visual strip searches are conducted in the inmate’s cell was a factor in determining their reasonableness.
In sum, evidence in the record supports the district court’s finding that NSP’s strip search policy was reasonably related to legitimate penological interests.
II. INFRINGEMENT OF PRISONERS’ PRIVACY RIGHTS
Michenfelder also alleges that the routine strip searches are unconstitutional because female correctional officers and visitors can observe their occurrence. In the same vein, he contests the prison’s practice of sometimes employing female officers for shower duty.
We recognize that incarcerated prisoners retain a limited right to bodily privacy. Shielding one’s unclothed figure from the view of strangers, particularly strangers of the opposite sex is impelled by elementary self-respect and personal dignity.
2
Grummett v. Rushen,
Therefore, the issue here, therefore, is whether NSP’s female officers regularly or frequently observe unclothed inmates without a legitimate reason for doing so. As in Grummett, female officers at NSP are not routinely present for strip searches. The record fails to show that Officer Jenae Holmes’s alleged presence at a search involving Michenfelder was anything but an isolated incident, nor could the witnesses testify with certainty that she was actually observing the search from her position at the lock box in the main corridor. The record does support the magistrate’s finding that the control bubble’s video monitors would provide at most an indistinct, limited view should female officers, contrary to prison policy, closely watch the searches rather than simply monitor all the screens for unusual activity. Evidence of female officers’ role in shower duty likewise did not establish an inappropriate amount of contact with disrobed prisoners.
The third
Turner v. Safley
factor has special relevance here. Prohibiting female employees from working in the control bubble, or requiring them to be replaced by males for the duration of strip searches, would displace officers throughout the prison. The prison’s current allocation of responsibilities among male and female employees already represents a reasonable attempt to accommodate prisoners’ privacy concerns consistent with internal security needs and equal employment concerns.
See Grummett v. Rushen,
With regard to visitors’ opportunities to view the searches on the video monitors, the evidence supports the magistrate’s finding that opaque screens covering the windows of the control bubble prevent visitors and attorneys from discerning anything other than “some movement” on the screens.
III. EIGHTH AMENDMENT CLAIM REGARDING USE OF A TASER GUN
Michenfelder also contends that the prison’s policy of allowing its guards to carry taser guns and to use them to enforce compliance with orders constitutes cruel and unusual punishment in violation of the eighth amendment. This is a question of first impression in our circuit, and, as best we can tell, for other circuits as well.
Michenfelder was threatened with a ta-ser when he refused to submit to a strip
*335
search outside his cell upon returning from recreation. Guards informed Michen-felder that the inmate taken inside immediately before him, upon insisting he be strip searched in his cell, was shot twice with the taser before complying. Michenfelder himself, however, was not actually shot with one. The district court found NSP’s use of tasers constitutional. Presented with a slim record regarding the taser’s adverse effects on humans, the court concluded, “It seems safe to assume that the [Nevada State Board of Prison Commissioners] received input from persons with experience and expertise before prescribing the Regulation.”

Michenfelder,
“Whatever rights one may lose at the prison gates, ... the full protections of the eighth amendment most certainly remain in force. The whole point of the amendment is to protect persons convicted of crimes.”
Spain v. Procunier,
The Supreme Court has said that administering electric shocks to prisoners as punishment for misconduct was “unusual”.
Hutto v. Finney,
In
Spain v. Procunier,
[U]se of the substance in small amounts may be a necessary prison technique if a prisoner refuses after adequate warning to move from a cell or upon other provocation presenting a reasonable possibility that slight force will be required____ The infliction of pain and the danger of serious bodily harm may be necessary if there is a threat of an equal or greater harm to others ...
Id. at 195.
Nevada’s Department of Prison Regulation 405 specifies that tasers are for controlling potentially dangerous situations, not for punishment: “When situations arise, such as an inmate who refuses to leave his cell, in which physical handling is inadequate and in which the use of batons would be inappropriate, the use of tasers or stun guns may be employed.” NSP authorities believe the taser is the preferred *336 method for controlling prisoners because it is the “least confrontational” when compared to the use of physical restraint, billy clubs, mace, or stun guns. 5 . By disabling the inmate, it prevents further violence.
Apparently, long-term effects of tasers are currently unknown. While the record regarding the risk of tasers is sketchy at best, Michenfelder has not cast doubt on the State’s evidence of safe use and low risk of long term adverse effects. The evidence before the district court included the manufacturer’s literature regarding testing on animals, which the court credited. Also, when contrasted to alternative methods for physically controlling inmates, some of which can have serious after effects, the taser compared favorably. At trial the only evidence of the taser’s harmful effects was anecdotal. Michenfelder’s witnesses said they felt only nausea, slight headaches, and “long-term anger.” No one has been hospitalized at NSP as a result of a taser shot. Though Michenfelder argues that the court should have postponed trial on the merits so he could line up evidence of long term effects, and though such an endeavor might have produced useful results, Michenfelder’s failure to pursue evidence diligently before and during trial precludes him from claiming prejudicial error. We do not lightly find abuses of discretion in decisions to limit discovery or to consolidate hearings. See Section IV.A., infra. Our affirmance of the district court is not, however, to be taken as holding that use of a device whose long-term effects are unknown would never violate the eighth amendment, nor that research could not uncover evidence of adverse long-term effects that would call into question the use of tasers. We simply find that Michenfelder has failed to meet his burden. See infra note 3.
A finding that the taser gun is not per se unconstitutional would not validate its unrestricted use. “[T]he appropriateness of the use must be determined by the facts and circumstances of the case.”
Soto v. Dickey,
IV. ALLEGED PROCEDURAL VIOLATIONS
Michenfelder’s brief on appeal raises several procedural issues, including the magistrate’s limitation of pretrial discovery of prison procedures and the warden’s schedule, consolidation of the preliminary injunction hearing with the trial on the merits, failure to appoint lay counsel, inadequate access to library facilities, and the magistrate’s failure to view personally the prison setup. The State, on its part, has moved to strike portions of Michenfelder’s brief on appeal. We have carefully considered each contention in turn and find them meritless; only the consolidation issue and motion to strike warrant elaboration.
*337 A. Consolidation of Hearing on Preliminary Injunction and Trial on the Merits
The magistrate consolidated the hearing on Michenfelder’s preliminary injunction with the trial on the merits, as permitted by Fed.R.Civ.P. 65(a)(2). The district court approved the order.
Rule 65(a)(2) provides that “[bjefore or after the commencement of the hearing of an application for a preliminary injunction, the court may order the trial of the action on the merits to be advanced and consolidated with the hearing of the application.” Fed.R.Civ.P. 65(a)(2). Before a consolidation order may issue, the court must give the parties “clear and unambiguous notice [of the court’s intent to consolidate the trial and the hearing] either before the hearing commences or at a time which will still afford the parties a full opportunity to present their respective cases.”
University of Texas v. Camenisch,
The district court’s consolidation order issued five weeks before trial and seven weeks after filing of the complaint. We have on occasion upheld a district court’s failure to give any notice whatsoever before finally determining the merits after only a preliminary injunction hearing, where the complaining party has failed to show how additional evidence could have altered the outcome.
Rosenthal v. Carr,
Michenfelder argues that the consolidation prevented him from obtaining expert witnesses on the psychological harm caused by strip searches and the long term adverse effects of tasers. We must consider this latter allegation carefully. “Eighth Amendment judgments ‘should neither be nor appear to be entirely the subjective views of judges,’ but such ‘judgments should be informed by objective factors to the maximum possible extent.’ ”
Soto v. Dickey,
*338 B. Motion to Strike
The State filed a Motion to Strike portions of Michenfelder’s brief on appeal; specifically, it moved to strike two diagrams purporting to depict the layout of Unit Seven and the location of the strip searches on an individual tier, and copies of correspondence between Michenfelder and various doctors.
The diagrams are simply a visual depiction of verbal testimony at trial describing Unit Seven’s layout and where the searches were conducted. The State does not argue that the diagrams are inaccurate or misleading. In light of the latitude we prefer to allow pro se plaintiffs, we decline to strike the relevant diagrams. We grant the motion to strike the correspondence. It was never made a part of the district court record and does not appear to bear on the merits of this appeal.
CONCLUSION
The Supreme Court requires us, when ascertaining whether a regulation that impinges on inmates’ constitutional rights is reasonably related to legitimate penological interests, to accord great deference to prison authorities’ judgments regarding the necessity of the regulation. We accordingly affirm the district court’s finding that the routine strip search procedures at the Nevada State Prison, even when conducted outside the inmates’ cells by officers carrying taser guns and where female employees might occasionally view them, did not violate Michenfelder’s fourth and eighth amendment rights. Consolidation of the preliminary injunction hearing with trial on the merits was not so prejudicial to the plaintiff as to constitute reversible error.
The judgment of the district court is AFFIRMED.
Notes
. Not all four factors will be relevant to each case. For example, the second Turner factor— availability of other avenues for exercising the right infringed upon — is much more meaningful in the first amendment context than the fourth or eighth, where the right is to be free from a particular wrong.
Though all our prior decisions employing the
Turner O’Lone
analysis have involved infringements of inmates’ first amendment rights,
Reimers
v.
Oregon,
. This case involves the asserted privacy interest of a prisoner from being viewed while nude by a person of the opposite sex.
. The State correctly points out that
Grummett
used a least intrusive means test that has since been rejected in
Turner v. Safley. See also Kent v. Johnson,
. Such assumptions can never be made safely.
Cf. People v. Sullivan,
. "Stun gun” as used by NSP witnesses refers to a device that shoots a "bean bag" projectile that will stun the target. In many places, however, “stun gun” is a synonym for taser.
