The PVS14 6015 is compatible with most all PVS-7 accessories including: the soft head mount straps and helmet mount fixture, 3x lens adapters, batteries, magnetic compass and more. The lightweight of the PVS 14 6015 night vision system makes it easy to use in extended operations. Most troops prefer the single eye monocular style to the dual eye single tube systems (like PVS-7 5001). The monocular style allows the soldier to maintain night eye adaption in one eye while using the night vision device with the other eye. Additionally, using a single eye device is more natural in a depth perception scenario. The dual eye single tube systems can give the user a false sense of depth perception which can get them in trouble quickly. Troop comfort and multi function usability are the main reasons that the PVS14 6015 is becoming the prefered night vision device for US Military ground forces.
