The Power Ultimate is designed for quick and easy set-up of most compound bows and crossbows. This press is perfect for both home and shop use, and it's effortless to use. Each LCA press model is equipped with the LCA patented finger system that allows you to press your bow precisely as if it's being drawn back. While pressing your bow, you're not applying any extra pressure to your limbs, and you're also not applying torque to your riser. The Power Ultimate moves in and out using a powered motor for fast and smooth movement. This particular press model has a range that spans from 11" - 54" axle to axle length. Ultimate units use a much thicker grade material so that the press itself is strong enough to handle high poundage crossbows.
