02Pros and cons
From the published specs, not owner reports.
For it
- Built-in laser rangefinder
- Swappable battery pack, so a spare doubles the run time
- Weather-sealed (IP65), fine in rain
- Records video and connects to a phone app
Against it
- Only 4 h of battery
- Heavy at 21.2 oz, 19th-heaviest of the 112 handhelds here
- Entry-level 384×288 sensor, with less detail than a 640
- Narrow 7.5° view, so a moving animal is hard to find
- Rangefinder but no ballistic calculator, so holdover is up to you
