HeliCoil technology is the engine behind Ravin Crossbows. This revolutionary technology delivers several industry-changing advantages that work together to create the most accurate crossbow ever designed. HeliCoil technology coils cables away from both the top and bottom of the cams in helical grooves keeping the cams perfectly balanced. This allows the cams to rotate an incomparable 340 degrees, while both cams remain perfectly level when drawing and shooting. This revolutionary design creates an incredibly compact crossbow filled with features that produce rifle like down range accuracy.
