RangeFinder

Lan Hai RangeFinder

It was my first concern if a non-famous branded optical device really helps or instead produces more optical illusions?
To my relief, not only does this device perform as well as it claims to be, it is also very easy to use and locks on target fast and accurately. The size of this device is small in comparison but it does not limit its accuracy and performance at all. Tested at the driving range during a practice session, it helps pinpoint targets at ease... 28 yards, 67 yards, 144 yards, 256 yards, etc.

1. It is good to know the yardage markers at the range are accurate and also able to determine the distance in between.
2. It is only ½ the market price of branded devices
3. It is good to know that my depth perception is actually quite deceptive, even though I had believed it was reliable.

Thanks to this little device, golf swing is more meaningful with distance control.
