NIVISYS' TQP (Tactical Quick Peek) tri-fold periscope is a hand-held unit that solves some real tactical problems for military and law enforcement. The NIVISYS TQP can be deployed in 15-seconds from its compact carry take-down configuration. Simply unfold the hinged one piece unit (no separate pieces to assemble), hand-tighten the connectors and the TQP is ready to use to safely peer down hallways, up, over and around obstacles and yet keep the operator safely behind protective cover. The TQP can be combined with NIVISYS' MUM-14 ultra-compact night-vision monocular (with built-in IR light source) for night- or low-light operations.
