Golf is all about yardage to the pin, but laser range finders are expensive. PinRanger to the rescue!
Just take a picture of the pin, drag the arrows to match the pin height and presto! You've got yardage. Fast, reliable, and comparable to expensive laser range finders. Consistently within 1-2 yards of the $400 lasers!
PinRanger comes pre-calibrated so you are ready to go. If you need to re-calibrate for any reason (change in pin height at a different course), go right ahead, it just takes a second.
You already carry your phone, why not use it to get yardage?
