Overview
A 7x25mm laser rangefinder monocular from Sig Sauer rated to a 5,000 yard maximum reflective range, built for long-range hunters and shooters who want onboard ballistics and Bluetooth links to external devices.
The KILO5K carries Applied Ballistics Ultralite onboard along with environmental sensors, and it supports BDX External connections to devices like Kestrel and Garmin units for combined wind and ballistic data. Its OLED display brightness adjusts automatically between bright sunlight and low-light dawn or dusk conditions, which several buyers specifically credited for keeping targets visible without blowing out the display.
- 5,000 yard maximum reflective range, 7x25mm optics
- Gen II LightWave DSP with Extended Range and Fog modes
- First, Best and Last target selection
- SpectraCoat anti-reflection lens coatings
Who it's for
Suits hunters and long-range shooters who already run a Kestrel or Garmin BDX-compatible device and want a rangefinder that talks to it directly. Less suited to shooters who plan to mount the unit on a tripod for extended glassing.
Pros and cons
- Applied Ballistics Ultralite and environmental sensors built in
- Pairs with Kestrel and Garmin devices via BDX External
- OLED display brightness adapts between sunlight and low light
- BaseMap app support for marking ranged targets
- No 1/4-20 tripod mount included
- Light body can be harder to hold steady at maximum range
Performance notes
The unit's light weight makes it easy to carry, but the same weight was cited as a downside for holding the monocular steady at extended distances without a mount.
