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

ATN quotes 2,380 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

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)
Built-in laser rangefinder
Takes 18650 batteries you can swap in the field
14 h of battery, the longest of 344 here
Waterproof (IP67), survives a dunking
Records video and connects to a phone app

Against it

Rangefinder but no ballistic calculator, so holdover is up to you
Zoom past 3.5× is digital and gets blurry
