I have hunted with a Bowtech Tomkat for the last 4 years. I love the bow. I now have a Bowtech Diamond Black Ice that I can keep or get rid of. The Tomkat is 4 years old and has been shot a lot. The Black Ice is 2 years old and has hardly been shot at all. The main difference in the 2 bows is the Tomkat is binary and the Diamond is single cam. I don't know a lot about that kind of stuff. I'm going to shoot the Diamond today and that will tell me a lot but I was wondering if you guys could give me your opinons on the two bows and on binary and single cams?
In general Binary or any dual cam system will develop more energy than a single cam of the same draw weight. However, the single cam will generally draw smoother. Two cams generally have a more solid back wall than single cams. Both can be tuned to shoot equally well but I have had a generally easier time getting single cam bows tuned than 2 cam bows. Notice that I said "generally" a lot in there. There's lots of variations within the systems used by different manufacturers and even from bow to bow within the same model. I've owned, shot and/or set up dozens of both kinds and I don't really have a preference for one over the other system. I do like a smooth bow though with a solid wall and I found that in the Elite Z-cam binary. It's even smoother than my Mathews DXT single cam.
There are also hybrid cam systems. My bow (vendetta xs) has that system. It draws smooth and it's fast as hell. I shoot a short draw length (28") and a low weight (57#), and just changed arrows which increased my weight by nearly 100 gr, and my arrow dropped 2-3" at 30 yards when resighting. I also shot a lot of other bows before buying this one. I think they're going to develop the hell out of the hybrids, they're nice.
I shot the Diamond yesterday. I belive I'll stick with my Tomkat. The Diamond was not near as smooth or quiet as my Tomkat.
