Overview
A 6x22mm laser rangefinder rated to 3,000 yards on reflective targets, with a red OLED display and five range modes including archery and two Applied Ballistics BDX modes for scope pairing. It stores 25 bullet profiles across 8 onboard ballistic groups.
The BDX connectivity is the feature that separates this from a plain rangefinder: paired with a compatible Sig scope over Bluetooth, it can transmit holdover data directly rather than leaving you to read a card.
- Ranges to 3,000 yards on reflective targets

Who it's for
Hunters and long-range shooters, particularly those already using or planning to use a Sig BDX-enabled riflescope, who want ranging and ballistic data in one device. Less suited to someone who wants a rangefinder they can pick up and use with zero setup.
