Steiner quotes 1,830 m, 2.5× 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

640×512 sensor, 3× the detail of an entry-level 384
Takes 18650 batteries you can swap in the field
9 h of battery, 81st-longest of 344 here
Light at 16.2 oz, 13th-lightest of the 194 riflescopes here
Records video and connects to a phone app

Against it

Short 35 mm lens: a wide view, but less reach than a 50 mm scope
No rangefinder, so you judge distance by eye
~$4,600, well above the ~$3,000 typical for riflescopes here
