I used to bowfish when I was a teenager but, I haven't since then. I recently bought some ground that borders the Missouri River. Our creek has been backed up for some time now because of the high river level. My son saw a large gar in the creek and was excited about it. I told him some stories about when I used to bowfish and he has gone nuts about the idea. His birthday is next week and he has asked for a bowfishing rig. He is going to be 10 years old and weighs about 75-80lbs. He has a PSE spider compound that shoots up to 30lbs. I used to use a junk shoot-through-the-spool rig and I don't know anything about the new equipment. What would you recommend for a set up? Will his bow be alright? Should I modify his arrows and how? Any advice is appreciated.
