Compound bows are different from what we would class as traditional bows such as long bows and recurve bows due to the cams and pulleys that dramatically reduce the draw weight. Without the cam system of a compound bow it would be virtually impossible to draw back the string to generate the extreme speeds that these bows are capable of.

But there’s more than just one type of cam system. Virtually every bow maker uses their own innovative variation on the original cam to give their bows the edge over the competition.

The different types of cams you’re looking at are single cams, dual cams from Mathews Archery, binary cams, hybrid cams, eccentric cams, perimeter weighted cams, among others. Each cam system gives the shooter a variety of benefits whether it be the ability to adjust the draw length or simply smooth out the vibrations that comes from generating huge amounts of power.

Another variation of the single cam, for example is the brand new XTR Cam and 1/2 from Hoyt Archery promising further benefits. 

No matter which bow you buy the cam system is going to be a major selling point on the part of the bow manufacturer. Take note of the kind of cams that are used in the bow and maybe find out what makes these cams so special. If the explanation appeals to you then you should give the bow a try.
