Our view
The Coolshot 20i GIII makes a compelling case on weight alone — at 130g it is the lightest slope rangefinder you can buy in the UK and the difference is immediately noticeable compared to heavier competitors. Nikon optics are characteristically clear and the ID Technology implementation is clean. The honest limitations are the 2-yard rather than 1-yard accuracy and the absence of a magnetic cart mount. The GolfMagic review compared it directly against the Shot Scope Pro L5 and concluded Nikon wins on optics clarity while Shot Scope wins on OLED display and GPS app connectivity. At £179 versus the Pro L5 at £169, the choice comes down to whether you prioritise Nikon optics and compact weight or OLED display and free GPS. Both are strong at their price points.
Pros
- Lightest slope rangefinder available in the UK at 130g — genuinely pocketable
- ID Technology shows slope-adjusted and actual distance simultaneously
- First Target Priority at this price is unusual and genuinely useful
- Dioptre adjustment benefits glasses wearers
- 5-year warranty is class-leading at this price point
- Tested at Royal Troon by reviewers — proven in Scottish links conditions
Cons
- Accuracy to within 2 yards rather than 1 yard — slightly less precise than competitors
- No magnetic cart mount — requires separate accessory
- LOCKED ON QUAKE (single) rather than DUAL LOCKED ON QUAKE — no visual cue
- Slope turns off via button combination rather than external switch
- No GPS, no app connectivity

Golfers who walk the course and want the lightest possible slope rangefinder.

The 5-year warranty makes it a strong long-term buy at the entry slope price point.
