I use a trap called a "Do-All white Wing". Ive had it for several years and I really like it.
Runs on a 12 volt battery; easily fits in the back of my Ranger. Throws a clay 70 yards!
Holds 50 clays. I have a wireless remote so I can move any where on the field for a variety of shots. I also have an optional attachment that moves up and down and from side to to side which adds more difficulty and more fun.
Best part, for me, is that I can go break some clays by myself...don't need a little guy to throw 'em.
It's great! Maybe sounds like I work for these guys...nope.
