Sig 2400ABS Rangefinder: Advanced Ballistics and Bluetooth Integration

The coolest thing about this rangefinder is its internal programing. It features what Sig calls “embedded applied ballistics calculator and Bluetooth for synchronizing with a free applied ballistics app.” In plain terms, this means the the rangefinder works with a smartphone app that will give you hold-over data. Plug in the required ballistics and weather data in the app, range a target, and the app automatically spits back your hold over. No math required.
