I use my deer hunting bow for bowfishing and it has worked great, but then again I never really get to deer hunt now so I don't worry about keeping my bow in perfect shape. I have a 55 pd Hoyt and my friend bowfishes with a 65 pound compound and they have both worked great. They really help with the long and deep shots like we often have from shore where I often bowfish and the arrows are so tough I have never had any problems, I have even hit rocks on shore multiple times and not had problems. One thing I have learned is for bowfishing it is much easier without all the potential bow accesories. When I started I had a peep sight, release, and fiber optic sights. With all this it is hard to quickly set up a shot and you miss out on allot. I now shoot the same bow but with an old sight with one pin with a round thing of sticky tac on it to aim, no peep sight, and shoot with fingers. I can get on the fish really easy and can pull back and shoot almost instantly like a recurve, and hit fast moving fish. I do know I have became much more accurate and confident since I started bowfishing and I imagine it will help your deer hunting as well.
