02Pros and cons
From the published specs, not owner reports.
For it
- High-resolution 1280×1024 sensor, 4× the detail of the common 640×512
- Sensitive sensor that picks out small heat differences on humid or rainy nights (56th-best of 285 that publish it)
- Built-in laser rangefinder
- Swappable battery pack, so a spare doubles the run time
- 12 h of battery, 8th-longest of 344 here
- Waterproof (IP68), survives a dunking
- Records video and connects to a phone app
Against it
- Heavy at 38.4 oz, 31st-heaviest of the 194 riflescopes here
- Rangefinder but no ballistic calculator, so holdover is up to you
- ~$5,999, well above the ~$3,000 typical for riflescopes here
- Zoom past 2× is digital and gets blurry
