Range finders

You often hear me talk about a shooting range of 20 to 30 yards when we’re bow hunting.  Let’s assume you are using an arrow and broadhead with a total mass of 400gr and a velocity of 325 feet per second.  At a range of 20 yards the arrow will fly nearly flat.  At 30 yards a well aimed arrow will experience a drop of about four inches; this will diminish slightly if you are shooting at a higher velocity.  If you are a proficient shooter the net result for the animal at this range will be the same…it will be dead. 

But what happens if you estimate 30 yards to your target and your estimate is off by 10 yards.  The additional drop between 30 and 40 yards can be about a foot.   Of course that will vary depending on whether you use a crossbow or a vertical compound bow and will also be affected by things like fletching, type of broadhead, arrow length, etc., but you get the idea.  The further the shot the greater and faster the drop.

Gauging distance is an art, and something that very few really master.  Things like backdrop, terrain, and sunlight will all affect depth perception and judging the range of a target becomes a best guess situation.  This applies to all firearms.  The only difference is that you are generally working with longer distances with a rifle, but the same principle applies.

Once again technology comes to the rescue and you no longer need to guess.  Modern range finders are compact, light, accurate and fast.  There are a wide range of models available to handle even the most demanding hunting conditions and environments. 

A laser range finder uses advanced laser technology to calculate the distance to your target with an accuracy of +- 1 yard.  When the button on your range finder is depressed the range finder shoots out a pinpoint concentrated beam of light.  The “computer” in the range finder calculates the length of time it takes for the beam to reach the target and return to the receiver.  It then converts that time calculation into a distance and displays that distance for the user. 

Advanced range finders can accurately estimate distances from 15-800 yards.  Look through the eyepiece like you would a scope and when you acquire your target simply press the button and the exact distance to your target will be displayed.  Be careful when using a range finder in wooded areas because the beam will reflect off of the closest reflective object it hits and will display that distance.  Make sure it is your quarry that you are ranging and not a twig or rock. 

Range finders have become so popular that Excalibur Crossbow has even developed a mount for your range finder that fastens right onto the scope and allows for instant ranging without taking your hands off the bow. 

The range finder won’t improve your shooting ability, but it will certainly remove the guesswork and increase your confidence in the shot you are about to take.  It should be one of those “must get” items for your hunting toolbox.
