Overview
Open fields at night and brush at dusk are the settings for this thermal imager, which works on its own as a scope, clips ahead of another optic or serves in the hand as a monocular. Ranging and holdover calculation are built in.
One device that scans, ranges and calculates holdover makes it flexible for hunters. The limits are weight and size for a clip-on, and missing figures for sensor resolution, detection range and runtime.
Who it's for
Night hunters who want to scan by heat and then range and shoot from the same unit fit the design. Daylight only shooters, or buyers who need documented detection range, should look elsewhere.
Pros and cons
- Laser rangefinder built in
- Standalone, clip-on and handheld
- Quick detach mount included
- Two batteries included
- Detection range not listed
- Sensor resolution unstated
- Battery life absent
- Heavy for a clip-on
Performance notes
The thermal sensor builds the image from heat, so it works in darkness. The laser rangefinder measures the distance and the ballistic calculator turns it into a holdover. Switching between rifle, clip-on and handheld use relies on the quick detach mount.
