The L3Harris AN/PVS-31A is an extremely light weight binocular night vision goggle. The PVS-31A was designed by L3 in conjunction with USSOCOM to replace the PVS-15. The unit features an articulating housing with manual gain, a battery pack, and incredible tube resolution.
The PVS-31 can be run both off of an onboard AA battery or powered from the included battery pack. Because of the light weight design, the user does not need to run a counterweight and can simply use the battery pack to balance the helmet. The PVS-31 battery pack also has an on board IR strobe for signaling and aerial identification. The IR strobe is operated by a single switch on the back of the battery pack. One great thing about the ability to run a battery pack is the speed in which the goggles can be up and running. With the PVS-31 the user simply can drop the dovetail on a Wilcox G24 mount and plug in the battery cable to the battery pack port on the PVS-31 housing and use their goggles.
