02Pros and cons
From the published specs, not owner reports.
For it
- Light at 7.2 oz, 3rd-lightest of the 112 handhelds here
- Waterproof (IP67), survives a dunking
- Records video and connects to a phone app
- Warranty: 5 years (10 years on sensor)
- Wide 17° view for scanning a field
- ~$429, well under the ~$1,995 typical for handhelds here
Against it
- Built-in battery, so no swapping in the field, and only 6 h of it
- No rangefinder, so you judge distance by eye
- Entry-level 256×192 sensor, with less detail than a 640
- Zoom past 1.2× is digital and gets blurry
