Get an old piece of muck bow. It will, I repeat, WILL, get water, mud, blood, and slime on it if you're doing it right. Some companies do make bows specifically for bowfishing, but I prefer to save a few hundred dollars and buy cheap 50# recurves. An old compound works as well. Some people prefer compounds for the extra punch, I prefer recurves so my arms don't get tired holding it all day. Depending on what reel you get will determine how you'll mount it.
