The bow and arrow was first developed by early man as a means of hunting for food. It meant that man did not have to kill his meat from close range, the bow and arrow enabling shots to be taken from a much longer distance than with a spear. Over the years the humble bow has evolved and been developed to the most recent incarnation, with the pinnacle of efficiency being the compound bow. One wonders what the earliest archers would make of a PSE X-Force Omen were it thrust into their hands.
The latest technology that has gone into the construction of compound bows has brought changes more rapidly than at any other time since they were first developed in the mid-nineteen sixties than any previous bow design. It is essential that the eccentric wheel system, which is either round or cam shaped, is machined extremely accurately in order for them to function properly.
When compared to a bow such as a recurve the compound bow reaches its peak weight much sooner. If drawn on a graph you would see a fast rise in the line mapping the amount of force used before it suddenly drops away as the cams take effect. This drop is known as “the valley” and although the draw force drops away the energy that can be passed on to the arrow by the bow is actually even greater.
For all of this ability to store and hold that energy at a fraction of the force required by other bows, it is however true that shooting a compound bow does not automatically turn you into a better shooter. The bow must be tuned until it best suits the shooter. There are a couple of important factors concerning how the bow will be adjusted and these factors are relative to the shooter himself. The first, the size and weight of the person, will determine the optimum draw weight. The second is the wing-span (or arm-length) of the shooter which will determine the draw length setting of the bow.
Getting the tuning of the compound bow right will set you on the path to becoming a competent shooter.
