Dynamics Laser Rangefinders use an invisible, narrow laser that is pointed at an object to determine the distance it is from the user. The laser beam is then reflected off that object and back to the laser rangefinder instrument. The rangefinder then uses a super high speed clock to determine the amount of time it took for the laser to bounce back and then uses a mathematical equation to calculate the amount of distance between the rangefinder and the target object. The whole process is called "Time of Flight" in scientific terms.
A rangefinder will tell you exactly how far you will have to hit the ball to get over the bunker, the tree, the water, or the green. The rangefinder will tell you how far you hit the ball and with time you will learn like a professional golfer what club to use under a particular set of circumstances. If you decide to add a rangefinder to your golf equipment I can promise you that will not be something you are going to regret - if your truly serious about improving your game. You will use it on most holes and you will most likely become addicted to your rangefinder, it will be like having your own - cheap version - of your personal caddy.
Last, it should be noted that all laser rangefinders feature a reticle (the crosshair or other type of aiming point you see when looking through your rangefinder). However, many rangefinders use LCD readouts with reticles that appear as black lines that you superimpose over the target you want to range but, this type of reticle if often difficult to distinguish against a dark background or in low light conditions. Therefore, other rangefinders have illuminated, LED, reticles as well. However, even though the brightness of the LEDs is adjustable (sometimes automatically), in bright conditions, it can be overwhelmed by the ambient light and thus it cannot be seen even at the highest settings and yet, in the evening when your eyes are accustomed to the lower light levels, the reticle is often so bright that it impairt your night vision even when set to the lowest settings. Also, this same issue pertains to the other information displayed on your screen such as yardage numbers and modes. Therefore, the best option is to choose a rangefinder with a backlight screen which gives you the capability to view your information in all light conditions.
