ATN quotes 1,190 m, 2.3× our figure, because makers usually measure against a person’s full height rather than their width. Why the numbers differ

02Pros and cons
From the published specs, not owner reports.
For it
- 8 h of battery
- Waterproof (IP67), survives a dunking
- Records video and connects to a phone app
- ~$1,495, well under the ~$1,995 typical for handhelds here
Against it
- Built-in battery, so no swapping in the field
- No rangefinder, so you judge distance by eye
- Entry-level 384×288 sensor, with less detail than a 640
- Zoom past 2.7× is digital and gets blurry
