Topdon quotes 1,280 m, 1.8× 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
- Built-in laser rangefinder
- Takes 18650 batteries you can swap in the field
- Weather-sealed (IP65), fine in rain
Against it
- Entry-level 384×288 sensor, with less detail than a 640
- Narrow 7.5° view, so a moving animal is hard to find
- Rangefinder but no ballistic calculator, so holdover is up to you
- Zoom past 1× is digital and gets blurry
