Overview
A Bluetooth-enabled laser rangefinder rated to 4000 yards, built with optical image stabilization, Applied Ballistics Ultralite, and coated lenses for hunting and tactical ranging use.
Optical image stabilization is meant to steady the image against hand shake, which matters most at the rangefinder's longer ranging distances where a shaky view makes it harder to hold on target. Onboard environmental sensors feed real-time data into the built-in ballistics calculator, and BDX 2.0 Bluetooth lets it pair with compatible SIG ballistic turrets. A 4x scan mode is aimed at quickly reading moving or multiple targets at range.
- Rated ranging distance up to 4000 yards
- Bluetooth BDX 2.0 connectivity
- Applied Ballistics Ultralite onboard
- Optical image stabilization
Who it's for
Suits hunters and shooters who want a rangefinder that pairs with a ballistics app and compatible turret dials rather than a standalone unit. Less necessary for anyone who only ranges at short, fixed distances.
