If you want to stick with bow and arrow I have quite a bit of experience using that before I went to compressed air launch. First, go to the store and buy a ball or football shaped lead sinker, the kind with a hole thru the center with a wire thru the hole (about the size of the end joint on your little finger). Cut the wire and pull out to leave an empty hole. Next get a drill bit just slightly bigger than a 6-32 machine screw and drill out the sinker hole so a 6/32 machine screw will slide thru the hole. While at Wal-Mart buy the longest aluminum arrow they have. Screw off the conical tip and you will see the arrow is tapped for 6/32 screw. Get a 6/32 machine screw long enough to go thru the weight and engage the threads in the end of the arrow. Now that you have your arrow prepared for launch I would recommend tying your fishing line behind the lead weight (between weight and arrow tip). That has been my set up and I have never lost an arrow. I did have one arrow that stayed in a tree over night but was on the ground the next day so it is good to have a spare arrow. The arrow does spin and thus will tend to twist the monofilament line. it will reduce the accuracy but you might want to adjust the feathers for minimum spin of arrow in flight. NEVER try to pull the arrow back across the limbs, if it appears to be hang-up just twitch the line and let the arrow fall to the ground. Remove arrow, reel in line, attach arrow to line and try again.

My air launch system http://www.akbeng.com/ uses a weighted tennis ball (total weight 4 oz) and it always comes right down plus if it ever hits anything there is less chance of damage.

Anyone have any advice for getting the fishing line to come back to ground zero?

I have no problem getting the line over a nice, tall branch but the arrow and tennis ball get caught up on the way back down. If I'm lucky, I can snap the line and retrieve the arrow, but that's only happened once.

I don't exactly have a bucket truck guy to call where I am (cottage). And I'm running out of cheap arrows.
