Rangefinder accuracy: what plus or minus 1 yard really means
Updated
Plus or minus 1 yard is the common maker claim, and it is plenty for choosing a club. Treat tighter claims with care. They are the maker's numbers, and on some listings they do not even match the maker's own page. What owners report about flag lock matters more than a decimal.
What the listings claim
| Rangefinder | Accuracy claim | Where we saw it |
|---|---|---|
| Callaway 300 Pro | +/- 1 yd | Listing and Callaway's page |
| Bushnell Tour V6 Shift | Not on the listing | Bushnell prints +/- 1 yd for the newer Tour V7 Shift |
| Blue Tees Series 3 Max+ | +/- 1 yd | Listing |
| Gogogo GS24 | +/- 0.1 m on the listing | Gogogo's page says +/- 1 yd |
| REDTIGER Golf Rangefinder | 0.5 yd | Listing |
The GS24 is the clearest case. The Amazon listing claims a tenth of a meter. The maker's own page says plus or minus 1 yard. When the two disagree, plan on the looser number.
Why owners still report "off" readings
Owner summaries for the Callaway 300 Pro, Blue Tees Series 3 Max+, GS24 and REDTIGER Golf Rangefinder all mention mixed accuracy. The accuracy claim assumes the laser hit the target you meant. A common cause of a wrong reading is ranging the trees behind the green instead of the flag. That is why flag lock signals exist. Bushnell's Visual JOLT flashes a red ring and vibrates. Callaway and Blue Tees use short vibrating pulses.
Check your own unit in five minutes
- On the practice green or range, find a marker or plate with a known yardage.
- Range it five times from the same spot. The numbers should stay within a yard or two.
- Range a flag with trees behind it. Watch for the lock signal before you trust the number.
- Do it while you can still return the unit.
