THE SYMMETRIC TWO CAM SYSTEM I ll start with the symmetric two cam system used on Bowtech, Prime and Elite bows. General Tuning Guide for Compound Bows One of my job at this year s ATA Show was to visit bow manufacturers booths to glean new, if any, tuning techniques take notes and present the information in a usable form for all dealers who read ArrowTrade. A few new ideas may be all it takes to keep customers happy and coming back into your shop. 68 Dealer er Workbench By Larry Wise Tuning Twin Cam Systems your own but it s always good to cross-reference your own ideas with others in case there s something new that you can adopt for your own use. The interchangeable module is visible on the bottom cam, which is on the right in this photo. Elite uses a bumper post that stops with contact on the limb as opposed to a stop on the cam draw-length module. I m sure you have some preferred methods of The Elite binary system is comprised of two symmetric cams that are timed and shot at the factory to ensure the bow meets advertised specifications. Since then, I ve learned more and more as newer cam systems have been developed but much of what I learned in those early days still applies and I present it all here for dealers to use as a guide for setting up bows for their customers.

I also learned much from a man you may recall: Tom Jennings. In fact, the four of us have become lifelong friends. Over the next two years, I learned a lot from the guys I shot with and against: guys like Jack Cramer, Ron Walker and Mike Leiter. I had to start from scratch and get sighted in again and by the following winter, I shot my first 300 (60 arrows) on a 3 inch white spot target.
JENNINGS COMPOUND BOW MANUAL HOW TO
In fact, I learned how to rebuild a compound by helping to install the new cables and reset the wheel timing, draw weight and draw length. That was the day I started learning how to tune the compound. Things were going really well until one June day, when both cables broke. That time, finger shooting didn t go well either, so the local Jennings sales rep, Henry Fulmer, gave me a Stanislawski back tension release aid and my shooting took off to new heights. The real test came in the spring, when I started shooting outdoors. I picked up a little target panic but there was no way I was going to give up after all, I d been shooting since I was eight years old and really enjoyed it. I shot it with fingers that first winter and competed in the league shoots at my local club. It was smooth to draw and aim and had all the bells and whistles of the latest design. That December, I ordered and received a new Jennings Arrow Star four wheeler. 1 My first compound bow was a Jennings Trail Boss two wheeler that I bought secondhand in I really didn t do much to it because I didn t know anything about the compound other than it had some letoff and was much faster than my recurve.
