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

Pulsar quotes 2,300 m, 2.2× 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
  • 640×480 sensor, 2.8× the detail of an entry-level 384
  • Built-in laser rangefinder
  • Swappable battery pack, so a spare doubles the run time
  • 10 h of battery, 33rd-longest of 344 here
  • Waterproof (IP67), survives a dunking
  • Records video and connects to a phone app
Against it
  • Heavy at 35.3 oz, 3rd-heaviest of the 22 binoculars here
  • Rangefinder but no ballistic calculator, so holdover is up to you
  • ~$6,200, well above the ~$3,999 typical for binoculars here
  • Zoom past 4× is digital and gets blurry
