Due to obligations I need to post a achieve blog from my old blog. Thanks for stopping by and I have a new blog next week. Same Matt time…same Matt channel!
When I attended the ATA in Columbus I was surprised that the single cam bows that I shot were smoother than the dual cams. I never realized this before my injury . I always made my choice on my personal feel of the bow. I know very little about the physics on bows but I wanted to do some research about why this happens. The basic reason for dual, which I’ll clump into double, hybrid and binary cam bows is 2 fold. More speed and more forgiving because you can back up the brace height to make the bow more forgiving. Single Cams are smoother and easier to tune, The bow manufactors make up speed by giving up the brace height, so your form better be good. Here is some detailed explanations on the different cam systems.
Single Cams Often described as a Solocam or One Cam, the single cam system features a round idler wheel on the top of the bow and an elliptical shaped power-cam on the bottom. The single cam is generally quieter and easier to maintain than traditional twin cam systems, since there is no need for cam synchronization. However, single cam systems generally do not offer straight and level nock travel (though the technical debate continues), which can make some single-cam bows troublesome to tune. Of course, all single cams aren’t created equal. There are good ones and bad ones. Some are very fast and aggressive, others are quite smooth and silky. Some offer easy adjustability and convenient let-off choices, others don’t. Most single cams do offer reasonable accuracy and a good solid stop at full draw. Overall, the smoothness and reliability of the single cam is well-respected. And the single cam is today’s popular choice on compound bows.
Hybrid Cams The Hybrid Cam system has gained considerable popularity over the last few years. The hybrid cam system features two asymmetrically elliptical cams: a control cam on the top, and a power cam on the bottom. The system is rigged with a single split-harness, a control cable, and a main string. Though originally invented and marketed by Darton Archery as the C/P/S Cam System, Hoyt’s introduction of the Cam & 1/2 in 2003 has brought hybrid systems into the limelight. Hybrid cams claim to offer the benefits of straight and level nock travel, like a properly tuned twin-cam bow, but without the timing and synchronization issues. Indeed, hybrid cams require less maintenance than traditional twin cams, but it’s probably a technical stretch to say that hybrid cams are maintenance free. They too need to be timed properly for best overall efficiency and performance. There are several hybrid cam models available which are impressively fast and quiet, rivaling the best of the single cam bows.
Dual Cams A Dual Cam system is sometimes described as a Two Cam or a Twin Cam. The twin cam system features two perfectly symmetrical round wheels or elliptical cams on each end of the bow. The PSE Omen was all the buzz last year at the ATA. When properly synchronized, twin cam systems offer excellent nock travel, accuracy, and overall speed. However, twin cams do require more maintenance and service to stay in top shooting condition. But thanks to today’s crop of advanced no-creep string fibers, they are becoming increasingly easier to maintain. Many hardcore competition shooters are quite loyal to the twin cam concept. And it’s probably worth noting that the twin cam bow is dramatically more popular outside of the US and Canada, where there is less advertising to hype the single and hybrid systems. Aside from maintenance issues, the only true disadvantage to twin cams is the tendency for increased noise. Nonetheless, the twin cam is still the cam system of choice for many serious shooters. Twin cams are also very popular choice for youth bows.
Binary Cams Introduced by Bowtech Archery as a new concept for 2005, the binary cam is a modified 3-groove twin-cam system that slaves the top and bottom cams to each other, rather than to the bow’s limbs. Unlike single and hybrid systems, there is no split-harness on a binary system – just two “cam-to-cam” control cables. This creates a “free-floating” system which allows the cams to automatically equalize any imbalances in the limb deflections or string and control cable lengths. So technically, this self-correcting cam system has no timing or synchronization issues and should achieve perfectly straight and level nock travel at all times. While this technology is still developing, the binary cam concept is clearly turning heads in the industry. Bowtech’s binary cam models were among the fastest bows on the market for 2005 and 2006, and they attracted a number of copy-cats in beginning in 2007. Only time will tell, but I think that the binary cam and its variants will continue to gain popularity. I found this information on New York Bow Hunters web site for people with injuries: Choose bows which have round wheel eccentrics or soft cams. Dual cam bows with hard cams take their toll on the back, shoulder and elbow. By utilizing a softer wheel or cam, additional stress from drawing back the bow is relieved from these areas. Hunters may find that some solo cam bows also draw very smoothly and can be utilized by the Physically Challenged hunter. Choose a bow with a “Deflexed” riser. A Deflexed riser is more forgiving and makes for a smoother drawing bow. Choose a bow with an axle to axle length of at least 34 inches. Bows with longer axle to axle lengths are more forgiving and make for a smoother drawing bow. They also place less stress on the hunter’s hand and wrist while drawing the bow.
Thanks, Drive safely!
