02Pros and cons
From the published specs, not owner reports.
For it
- Smooth 60 Hz picture on a running animal
- Built-in laser rangefinder that feeds the ballistic calculator
- 10 h of battery, 33rd-longest of 344 here
- Records video and connects to a phone app
- Warranty: 5 years
Against it
- Sensitivity (NETD) not published
- Built-in battery, so no swapping in the field
- Short 35 mm lens: a wide view, but less reach than a 50 mm scope
- Entry-level 320×240 sensor, with less detail than a 640
- Narrow 6.3° view, so a moving animal is hard to find
- No waterproof rating published
