Pard quotes 1,200 m, 2.3× 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
- Sensitive sensor that picks out small heat differences on humid or rainy nights (the best of 285 that publish it)
- Built-in laser rangefinder
- Swappable battery pack, so a spare doubles the run time
- Waterproof (IP67), survives a dunking
- Records video and connects to a phone app
- ~$999, well under the ~$3,999 typical for binoculars here
Against it
- Only 4.5 h of battery
- Entry-level 256×192 sensor, with less detail than a 640
- Narrow 7.0° view, so a moving animal is hard to find
- Rangefinder but no ballistic calculator, so holdover is up to you
- Zoom past 4× is digital and gets blurry
