Traditional drop-away style arrow rests use launchers (the arms the arrow rest on) that are spring-loaded. When the arrow is released, the spring pulls the launcher down in the flight path of the arrow.
The problem with these designs is that the launcher is in the way of the arrow throughout much of the arrows travel. Additionally, in many cases, the launcher bounces back into the path of the arrow causing it to hit the arrow, resulting in poor arrow flight.
Unlike traditional drop-away style arrow rests, Tri-Van Vanishing Rest™ use Vanishing Arm Technology™. The rest arms are mounted on a rotating ring that radially retracts the arms, much like a camera shutter upon arrow release. When the arrow is released, the arms retract and are never in the arrows flight path.
And, like a camera shutter, the Tri-Van Vanishing Rest™ arms react extremely fast. In fact, the Tri-Van Vanishing Rest™ is the fastest arrow rest on the market. Your arrow will never come in contact with the arms, resulting in increased arrow speeds, increase kinetic energy and accurate arrow flight.
