Calculated from the sensor's pixel pitch and the lens focal length, for clear air.

ATN quotes 1,300 m, 2.5× 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

640×512 sensor, 3× the detail of an entry-level 384
Sensitive sensor that picks out small heat differences on humid or rainy nights (56th-best of 285 that publish it)
Waterproof (IP67), survives a dunking
Records video and connects to a phone app
Warranty: 5 years
Wide 17° view for scanning a field

Against it

Built-in battery, so no swapping in the field, and only 6.5 h of it
No rangefinder, so you judge distance by eye
Zoom past 1.75× is digital and gets blurry
