US Night Vision Corp.'s PVS-14 is a versatile, multi-purpose night vision system. The PVS-14 monocular features automatic brightness control, a built-in IR illuminator, and manual gain control. The system's manual gain control allows the user to increase or decrease image tube brightness for greater image contrast in varying light conditions. The system can be hand-held, weapons mounted, camera/camcorder adapted, or head/helmet mounted for a hands-free application. US Night Vision's PVS-14 now comes with a new five-year limited warranty.
