What great information,, so yo leave your gun rigged with the mono test line and after the binge and clip you attach your spearing line from the reel, correct. I have not seen a close up of this or do you simply remove the bungee and run the line from your reel to the swivel that attaches to the mono line on your spear?
yes the typical way is to remove the bungi. The bungi primarily serves to keep the shooting line taunt before the shot. With a reel, the drag is generally set just tight enough to keep the shooting line from falling off the gun prior to the shot.
