Thanks to the sliding adjustable spring clip on the throwing arm, you can launch any of the five standard targets as either singles or stacked doubles with the convenience of a three-quarter cock. Unlike with a full cock, a three-quarter cock turns only 75 percent of the way through the cycle when the target is thrown, and only requires the trapper to push the arm through the last quarter of the arc. Subsequently, the true roller-bearing clutch and counterbalanced arm assure that the final quarter motion is accomplished with a minimum of effort, so people of any age can operate it with ease. Other details include heavy-duty steel and aluminum construction, quick assembly, and a 10-year or 1 million target warranty on the roller-bearing clutch.
