Despite its relatively quiet “soft launch” at SHOT Show 2023, the Holosun DRS-TH thermal red dot sight created quite a stir. More specifically an RDS with fusion thermal overlay, the DRS-TH is a multi-reticle red dot system with thermal imaging capabilities and the capability of recording pictures and video.
And it’s WiFi compatible.
The optic features an LED Multi-Reticle System (MRS) with two user-selectable digital options and five different available perspectives (including White Hot, Black Hot, Highlight, Outline, and Fusion modes) for thermal viewing. It employs a 256 x 192 thermal sensor and utilizes a 1024×768 OLED resolution display with an 8x digital zoom capability; this allows the recording at 50fps. Onboard storage allows the user to store these images and videos.
The Holosun DRS-TH is housed in a lightweight 7075-T6 aluminum body with an anodized finish and is IP67 waterproof rated. It’s powered by (rechargeable) 18350 lithium batteries, keeping it in operation for up to 12 hours on a single charge during regular use; and 7 hours if using WiFi or recording.
Mounting is done via a standard Picatinny rail mount and viewing through a multi-coated, large-aperture lens.
The DRS-TH optic utilizes Holosun’s Shake Awake technology, turning itself on when not in use and turning it back on immediately when it senses movement. This will preserve battery life.
