I almost didn't look, but, ah, the old Bowmaster. Yes, I'm on my second one. The first one wouldn't adjust short enough for these shorter bows. And it works like a dream.

I've got a bench mounted Apple, but it hasn't seen any use in several years. The Bowmaster is a bit slower, but most of my adjustments are not made at home, but out at the range when I'm tinkering.

I have made adjustments and even torn bows down completely with it. One of the better attributes is that there is no way to bend a riser as all the pressure is near the limb tips. I also use the split-limb adapters even on solid lomb bows.

Portable? You can wrap it up and put it in your hip pocket.

Yes, I use mine all the time.
