I agree on the shooting technique being the number one cause. If you can not shorten the draw length then you might want to try a new anchor point closer to your mouth if possible. I open my hand up and only use my thumb and first finger. This helps to rotate my forearm muscle (many years of weight lifting) out of the way of the string. We took a group of youth bow fishers out to a gravel pit near Bloomfield Indiana this summer. Guy that owns it has a pontoon boat on it and it is full of those asin jumping carp. They are hard to hit in the air but they tend to land in the boat anyway Took a twenty pounder in the shoulder and it left a bruise. Kids had a blast. Hope you had a good summer looking for carp this year. Got any good stories?
