If you’ve already decided to get into the sport of archery, bow hunting, or bow fishing, the most important thing you have to do is to choose the right kind of compound bow to use. The archery market is flooded with many good quality brand names to choose from, as well a variety of models specifically made in relation to the type of archery you are getting into. If you have no experience whatsoever in such things, you can always do some extensive research on related topics before deciding the brand and type you are going to purchase. A compound bow might be in principle a simple and an easy to understand piece of archery equipment, but using one, and getting familiar with how it works is an entirely different story.
Compound bows have many different working parts, components, and accessories that when combined make it a marvelous and superb piece of shooting equipment. It utilizes a system of pulleys (cam) and cables that enables any archer to pull back the strings effortlessly and efficiently. Its accuracy is further enhanced by the use of sight pins, anti-vibration systems, draw-stops, and many more incorporated elements not found in the recurve and long bows. The two most commonly known Compound bows are classified as Single Cam, and Twin Cam.
The Single Cam system is the best compound bow for aspiring beginners, as this type of bow is the most basic of its class having the advantage of not needing to be synchronized as that of a Twin Cam bow. The idler wheel at the top of the limb does not provide any mechanical advantage but serves only to unroll the string when the bow is drawn. The bottom cam controls the cable as the string is drawn, and at the same time letting out the other end of the string at a controlled rate to keep the nock move straight back and forward. The changes in power cable length does not affect this type of system; when the power cable is stretched, the bow stays in tune with a single cam.
The Twin Cam system bows started being problematic with its designs when these became too aggressive, making it very sensitive to synchronization problems. The cams will not turn over properly if either one of its harness is not of equal length. Twin cam bows need daily check ups with its timing to keep them in top performing condition.
Overall, the Single Cam bow is a much better choice compared to the Twin Cam bow. One important thing to remember though is to ask the salesperson if the bow you’re about to purchase can be tuned or not.
