Hi, sorry I know this has probably been asked a lot but what the difference between single and duel cam? My last bow was duel and worked but now I’m looking at singles and wondering what the difference is if any, cheers.
Dual or binary cam bows are typically a tad faster. It is easier to design an agressive draw force curve on them. Many have draw stops so generally they have a more solid wall. They are thought to be a little noisier than single cams.
Single cam bows are a tad slower in general, and they are though of as being a little quieter. In addition, they are less likely to go out of tune, and when they do the effect on arrow flight is not as significant as in 2 cam bows. The weakest part in the whole setup is the cable yoke (the Y part that attacches to the limb). If one of the arms of the yoke streches more than the other, the idler wheel might lean. In the past single cam bows where seen as being more precise and easier to keep in tune.
Nowdays with binary cams and non-streching string materials, it is just a matter of preference.
So in summary:
2 cams: faster + solid wall.
single cams: quieter + easier maintenance
Just my 2 cents, of course you will find lots of digressing opinions on this topic
