Pard quotes 1,800 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
- Sensitive sensor that picks out small heat differences on humid or rainy nights (104th-best of 285 that publish it)
- Built-in laser rangefinder
- Swappable battery pack, so a spare doubles the run time
- 8 h of battery
- Light at 19.5 oz, the lightest of the 22 binoculars here
- Waterproof (IP67), survives a dunking
Against it
- Rangefinder but no ballistic calculator, so holdover is up to you
- Zoom past 1.8× is digital and gets blurry
