This trigger release is loaded with great features. The new Adjusto Trigger Plus rotates 360 degrees, so the perfect thumb position setting is just a quick spin away. It's the most adjustable Carter ever! At the base of the trigger lever are three holes. The first one adjusts trigger travel while the other two are spring-loaded to affect trigger tension. The tension and travel setting options are endless. The cocking lever on the back closes the hasp with one motion. Place hook on release rope or D-loop, push cocking lever, hasp closes on rope or D-loop -- simple as that. It can be shot off a D-Loop or release rope attached to the release.
