Research the difference between the various rangefinders online and at a golf pro shop, as golf laser rangefinders vary widely in price and functionality. When buying, you need to narrow down the features you want based on your budget. A simple rangefinder will give you fairly accurate yardage, and some machines will use GPS technology to map the whole thing.
The driving range is set up with your clubs, balls and golf laser rangefinder, look through the viewfinder to ring out and find your target, whether it's a sign, bunker or other leading edge of an identified landmark. It's relatively easy to check. This is the time to read. A rangefinder requires a very steady hand. To find the distance, check that the rangefinder has a zoom function and the correct distance to use.
Once everything is in place, you need to play a few balls to test if the golf laser rangefinder is working properly. If it doesn't work, debug it again. If it still doesn't work, you need to consider whether the rangefinder is damaged.
