- 10 h of battery, 33rd-longest of 344 here
- Records video and connects to a phone app

Against it
- Sensitivity (NETD) not published
- Built-in battery, so no swapping in the field
- Heavy at 46.6 oz, 10th-heaviest of the 194 riflescopes here
- Narrow 5.9° view, so a moving animal is hard to find
- No waterproof rating published
- Zoom past 5× is digital and gets blurry
