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

Guide quotes 500 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
  • Light at 8 oz, 9th-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
  • ~$449, 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
