QuoteI have been toying with the idea of a line shaft sling...how do you connect yours and does it effect your firing at all?
I've used it at the Bahamas with great success. Here are some pics of the rigging. It's very simple. I attach the float line to the sling, the spear is attached to the sling with the shooting line. Doesn't affect accuracy at all. You can shoot any size fish and as long as you have some penetration you can play the fish with the float line. Better range than with a pole spear and you can't damage any component.
On this spear I have a spinning point with double barbs. Since the range is not very long this has no effect on accuracy, neither does the attached mono. Take any SS shaft, thread the end and drill a hole at the point that is closest to the sling when you're at maximum pull. This is where you crimp the mono, secure the other end of the mono to the sling, there are a variety of ways to do this. You can tie the sling to a float and tow it. You can use a slip tip for the spear too. Big fish can be taken like this, I prefer this setup to a pole spear, it has more punch and 4 times more range.
