I use coveyor belt. Works like a charm! Same principle as the cow mat though, and the cow mat appears much easier to get. I just screwed mine onto my privacy fence and it does the trick. With a recurve they bounce or just the point sticks in (I used to shoot compound alot as well -- now that's a different story). It still shoots hard enough to penetrate both worn out 3-D target, the mining belt, and the 3/4" fence plank. :eek:
If you guys come up with a "mobile" set up, be sure to post it. I'd love to be able to move mine around the yard and change the scenery a bit. But I'm not the handiest man in the world when it comes to design structure.
