Give John Freeland a call. Hitchhiker target launcher. Goes in the reese hitch of your truck. I bought one from him a few years ago. Wasted alot of time with skeet throwers before I got it. I think his site is bluegridgeoctober.com
Mine is set up to through cardboard disks one at a time. I saw one he had rigged up to throw 5 clays and on top of that, he had three throwers stacked up. thats 15 clays in the air. It's a simulated covey rise.
give me a call if that don't work. I got his # somewhere. Don
