Hi fellas

I'm not sure if there is a post on all of this or not but could someone please point me in the right direction to start tuning a bow? Everytime I'm not shooting good or I think something is wrong with my bow, which in most cases is my fault but I blame it on the bow. I go to an archery shop. I've been to a couple places where it was more let me sell you something and that will make you shoot better and really that isn't going to make me shoot better at all because there is a bigger issue. I neverowned a dual cam bow. I don't know the first think about twisting cables,setting the brace height, axle to axle (I know this has nothing to do with a dual cam but the last couple do) or making sure my camsare in time, or that they are synconized. I've owned a single cam which I found out that the draw length isto long and I bought aBinary Cam Guardian. ( Do I have to check timing and being in sync on this?)
I really like the bow and I believe that I shoot good with it. The problem is what happens if something happens to the bow and it becomes out of tune and I can't take it back to the shop that set it up. I may never see that accuracy again ornot for a while until I find a good bow shop which aresometimeshard to find.

I would really like to learn everything there is about tuning and I understand that alot will come from experience and trail and error but I want to learn.


My main concern is I'm too dependent on an archery shop.

Is there a good book or website that will get me started?

Thanks
Jeff
