The VertiCoil Cam System rotates the ultra-small cams 720 degrees, coiling the strings and cables around the cam and cam axle, allowing an axle-to-axle height of just 1.3 inches cocked or 4.1 inches when uncocked, with a static overall width of 4.75". One of the revolutionary design advantages provided by HeliCoil technology is the Versa-Draw Cocking System. Working in conjunction with the Trac-Trigger Firing System this ultra-compact fully integrated cocking mechanism is built into the sleek stock design. Featuring a minimal 12 pounds of cocking force the Versa-Draw Cocking System is ambidextrous and has the ability to cock and un-cock your Ravin crossbow. A patented built-in trigger mechanism that slides forward on the rail and clasps directly to the precise center of the string every time the bow is drawn, allowing for straight-line nock travel. The Frictionless Flight technology allows the arrow and string to free float above the rail, eliminating friction for consistent accuracy and increased string and cable life.
