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. Reviewers consistently describe a real learning curve getting the modes and app pairing set up before the tool becomes fast to use in the field.
- Ranges to 3,000 yards on reflective targets
- 6x22mm optics with red OLED display
- 5 modes including archery and 2 BDX modes
- Stores 25 bullet profiles, 8 ballistic groups
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.
What buyers say
From Amazon customer reviews.
Hunters who paired it with a Sig BDX scope report accurate, fast range readings out to 600 to 1000 yards and successful shots based on its data. The recurring theme across reviews is a real learning curve: several buyers describe needing time with the modes and the Sig app or a linked Kestrel before the device felt fast to use, though most say it becomes effective once set up.
Strengths and trade-offs
Drawn from this product's published specifications.
- Accurate, low-lag ranging confirmed by hunters at 600+ yards
- BDX Bluetooth pairing sends data straight to a compatible scope
- Compact and lightweight with a clear OLED display
- Stores 25 bullet profiles across 8 ballistic groups
- Steep learning curve to configure modes and app pairing
- Wide feature set can overwhelm a casual user
- One reviewer found battery gauge readings inconsistent
Performance notes
The KILO3K uses Sig's Lightwave DSP engine to return a range reading with little lag, and reviewers using it on 300 WSM and similar rifles report it accurately transmitted range and holdover to a paired BDX scope out to around 600 yards in the field, with one buyer confirming a hit at 598 yards. Multiple reviewers flagged a genuine learning curve to configure its range modes and app pairing before it becomes fast to operate.
