02Pros and cons
From the published specs, not owner reports.
For it
- 640×480 sensor, 2.8× the detail of an entry-level 384
- Smooth 60 Hz picture on a running animal
- Takes CR123 batteries you can swap in the field
- Waterproof (IP67), survives a dunking
- Records video and connects to a phone app
Against it
- Sensitivity (NETD) not published
- Only 4 h of battery
- Heavy at 36.8 oz, 37th-heaviest of the 194 riflescopes here
- No rangefinder, so you judge distance by eye
- Narrow 5.9° view, so a moving animal is hard to find
- Zoom past 4.8× is digital and gets blurry
