The InfiRay Outdoor FINDER V2 combines a powerful thermal viewer with a handheld laser rangefinder, giving hunters the ability to identify targets at night and accurately determine their range. A 640A-512 thermal sensor paired with a 3A- 35 mm f/0.9 lens provides a crisp image with ample room for digital zoom, ideal for viewing wildlife or recording photos and videos.The FINDER V2 pairs 800-yard infrared laser rangefinding capability (continuous or single capture) with a 1,750-yard thermal detection range in a compact unit that fits in the palm of your hand. The FINDER V2 ships with two IBP-2 batteries, each providing 3+ hours of run time. A proximity sensor automatically powers off the display when moved away from the viewer's eye to reduce power consumption and visible light signature.
