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
- Takes 18650 batteries you can swap in the field
- Light at 15 oz, 5th-lightest of the 29 clip-ons here
- Waterproof (IP67), survives a dunking
- Records video and connects to a phone app
Against it
- Rangefinder but no ballistic calculator, so holdover is up to you
