SLOPEON/OFF

Pin-locking laser optics with slope compensation and a vibration pulse when it grabs the flag. Reads to 400 yards at half-yard accuracy, and the slope switch flips off for tournament-legal play. The number is the number — no more guessing the difference between 148 and 156.

Why we picked it

The coaching read.

The number is the number. Pin-lock optics grab the flag and pulse, slope compensation gives you the playing yardage, and half-yard accuracy removes the guess between 148 and 156.

The slope switch flips off for tournament-legal play, so one device covers practice and competition. Distance control starts with knowing the distance — this is where the data begins.

±0.5 yd to 400. Stop guessing the difference between 148 and 156.

“Locks the pin instantly and the jolt confirms it. Slope readings match my coach’s yardage book almost to the yard.”

“Half-yard accuracy is real. I stopped short-siding myself the moment I started trusting the number instead of pacing it off.”

“Glass is crisp and target lock is quick even into a busy background. Slope toggles off with a side switch so it’s tournament-legal — that sold me over the model I returned. Half a star off for a weak case magnet.”

Questions

Before you range it.

Is the slope mode tournament-legal?
The slope switch flips off, and with slope disabled the unit reads straight-line yardage that conforms for competition. Leave it on for practice to get the playing number, switch it off on the first tee of a counting round.
How accurate is it, really?
Plus or minus half a yard out to 400. In our bag testing the slope figure matched a coach’s yardage book almost exactly — close enough that you can stop guessing the gap between 148 and 156.
Does the colorway change anything?
Cosmetic only. Slate, Amber, and White share identical 6x optics, pin-lock pulse, and slope engine — pick the finish you will spot fastest in your bag.
What comes in the box?
The rangefinder, a magnetic cart strap, a CR2 battery, a hard case, and a microfibre cloth. It is ready to lock a pin the moment it lands.
