Today we will talk about just how a laser rangefinder functions. The distance to an objective is calculated by a rangefinder by the rebounding of a laser light beam off the object to be ranged. The time it takes for the laser light beam to reach the target and return is measured by a high speed digital clock. This time that commonly takes less than one second, is then computed by the rangefinder and displayed as a distance on the rangefinders build in screen.
Choosing the correct rangefinder for your needs can be a daunting task. What type do I need, do I need a GPS Rangefinder or a Laser Rangefinder, and maybe it should be an Optical Rangefinder. After you figure out the type you want, now you have to figure out what brand. Should I get Bushnell or Nikon, should it be Leupold or one of the many other brands? Oh yeah I need to know what features they have and do I need them and in some cases are they even legal to use on the golf course. Or maybe this rangefinder is for hunting or hiking and needs to be more accurate. Let’s first take a quick look at the type of rangefinder you may need. For golf and hunting you can use either a GPS Rangefinder or Laser Rangefinder. Both will help your game. GPS Rangefinder have mapping abilities that give you distances to various places on a golf course while the Laser Rangefinders tend to be more accurate. For hunting that increased accuracy may mean the difference between success and failure.
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.
