The cams rotate a full 360 allowing the bow when fully cocked to be 3.6inches in width and only 28inches in length. Along with unmatched speed and dimensions this bow has the new Electonic Drive System. This system allows users to simply press a button to cock and de-cock this bow with the included 500 draw handle. The Ravin Electric Drive consists of a 12-volt battery and motor unit that simply attached and detach to the stock.
