A good set up to get
 

This coming year I want to go bowfishing with my son. We will probly fish for carp. What is a good reel and line and arrow to get.

Hard question to answer with such little info. You want a spinner or an AMS retriever. Spinning reel you can't go wrong with a Shakespeare TI20 fishing reel and 200 pounds fast flight line. AMS retrievers break down less but are slower to retrieve the line in and they are ment to hand bomb the fish in. They take 200 pound braided line. Can't go wrong with muzzy arrows. Muzzy reels are the best in my opinion but very expensive. Hope this helps

Ya, wheel is right I use Muzzy spin cast and they work great if you abuse them like I do. I always take a hacksaw saw and 1 end of the double handle that way you cut the chances of trippin your bail by 50% See my YouTube video about this Brother Dave. How I do it ain't rocket science, but watch my vid anyway, just cuz i want ya too
