The J-Arm adapter interface allows mounting a night vision monocular or the HMD-800 unit to a compatible head gear or a helmet mount for hands-free operation. The monocular can be moved/swiveled between right and left eye. Additional knob helps to fine-tune angular position of the monocular to achieve maximum viewing comfort. The J-Arm has a built-in reed switch for added functionality: turns off the unit when removed from head-gear or helmet mount and turns off the unit when in flipped-up position.
