N-Vision quotes 1,360 m, 1.9× 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
Smooth 60 Hz picture on a running animal
Takes 18650 batteries you can swap in the field
Waterproof (IP67), survives a dunking

Against it

Sensitivity (NETD) not published
Short 35 mm lens: a wide view, but less reach than a 50 mm scope
No rangefinder, so you judge distance by eye
~$6,175, well above the ~$3,000 typical for riflescopes here
Zoom past 2.5× is digital and gets blurry
