The HEAT / VIPER 4.0 is a two-monocular kit: a HEAT thermal unit for spotting heat signatures and a VIPER digital night vision unit for identifying detail, joined by an included dovetail bridge. Run them bridged on a helmet, use either handheld, or split them between two people. The HEAT weighs 360 g with adjustable focus and diopter; the VIPER weighs 320 g and has built-in 850 nm IR. Both use a 1x wide-angle lens for natural depth perception, sit in machined-CNC chassis with rain resistance, and run on a built-in rechargeable battery rated up to 5 hours. The pairing is cheaper than most dedicated thermal units, but the 2.9 rating reflects real problems: dead-on-arrival units, incomplete shipments and weak support.

The Night Operators HEAT / VIPER 4.0 combo pairs a thermal monocular with a digital night vision monocular. The HEAT thermal monocular is for detection and scanning, finding heat signatures in total darkness. The VIPER digital night vision monocular provides detail for identifying what the HEAT finds.
The two units can be bridged together on a helmet, used handheld, or split between two people. The bridge is included, along with a G24 helmet mount.
The HEAT and PVS-14 pair on a simple two-screw rail bridge, which is not a true dual dovetail bridge.
