DNT Optics Hydra LRF 35mm Thermal Weapon Sight, 640 Core, 1.5-6x

The DNT Optics Hydra LRF 35mm Thermal Weapon Sight (DNT part no. HS635R) builds on the standard Hydra 35mm, 640-class thermal sight by adding a built-in laser rangefinder (LRF), letting a shooter range a target directly through the optic rather than carrying a separate rangefinder. The 1.5-6x zoom and 640-class sensor core match the non-LRF Hydra 35mm model in DNT’s lineup, so the added rangefinding capability comes without giving up detection performance, useful for shooters who want a single-optic solution for both thermal detection and precise distance data.
