ClayCopter UFO targets are an exciting way to be able to shoot shotgun targets at night. These luminescent targets require a UV light source to quickly charge them before launching. Caldwell has made the perfect solution in the ClayCopter UFO Charger Target Dispenser. The UFO Charger couldn't be easier to use. Simply attach the end caps over the ClayCopter Targets tube. Then turn on the UV lights and start charging the targets. After a few seconds, the targets are fully charged. An adjustable shoulder strap is included to keep both hands free to operate the launcher while keeping targets charged and at the ready.
