Pulsar quotes 1,800 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
- 640×480 sensor, 2.8× the detail of an entry-level 384
- Swappable battery pack, so a spare doubles the run time
- Waterproof (IPX7), survives a dunking
- Records video and connects to a phone app
Against it
- Heavy at 42.3 oz, the heaviest of the 22 binoculars here
- No rangefinder, so you judge distance by eye
- ~$6,100, well above the ~$3,999 typical for binoculars here
- Zoom past 3× is digital and gets blurry
