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 (the best of 285 that publish it)
- Smooth 60 Hz picture on a running animal
- Built-in laser rangefinder
- Swappable battery pack, so a spare doubles the run time
- Waterproof (IP67), survives a dunking
- Records video and connects to a phone app
Against it
- Only 4 h of battery
- Heavy at 23 oz, 12th-heaviest of the 112 handhelds here
- Rangefinder but no ballistic calculator, so holdover is up to you
- ~$4,499, well above the ~$1,995 typical for handhelds here
- Zoom past 2× is digital and gets blurry
- Warranty terms not published
