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
- 8 h of battery
- Waterproof (IP67), survives a dunking
- Records video and connects to a phone app
- Warranty: 5 years
- ~$1,645, well under the ~$3,999 typical for binoculars here
Against it
- 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 4.5× is digital and gets blurry
