Garmin Approach R10
Radar-only and pocket-sized at about 1 lb, with a roughly 10-hour battery that outlasts every camera-based unit in this price range -- the simplest all-day option here.
- Lowest price of the two mid-tier picks here, now commonly listed near $500
- 10-hour battery life, longest of the three
- Pocket-sized at about 1 lb
- Radar-only -- fewer directly-measured metrics than the camera-based MLM2PRO
- No onboard camera to visually verify a shot
