INTRODUCTION

Golf laser rangefinder is a portable opto electronic device that can be used to measure the distance of a stationary object within a certain range. It possesses advantages such as high accuracy, short measuring time, low power consumption and automatic power-off for power saving. It is advantageous at identifying small objects (such as flagsticks) from background targets, like trees or bushes, and locking the measurement data accurately.
This Device is widely used in traveling, game watching, golfing, hunting and other outdoor sports.
It's considered the best helper to improve your shot.
