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

ATN quotes 350 m, 2.4× 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

Sensitive sensor that picks out small heat differences on humid or rainy nights (104th-best of 285 that publish it)
8 h of battery
Light at 9.5 oz, 16th-lightest of the 112 handhelds here
Waterproof (IP67), survives a dunking
Records video and connects to a phone app
Warranty: 5 years
Wide 25° view for scanning a field

Against it

Built-in battery, so no swapping in the field
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
