As far as I am aware sling is sometimes referred to as a pole spear. Check the DEPI web for definition of a hand spear. I believe a hand spear has no rubber and can only have a max of two prongs. A sling is classified as a gun as mechanical propulsion is used by having a rubber.
Wouldn't use a conventional gun, to dangerous. Bit of a knack to spearing from air into water as there is an error due to refraction of light from water to air. Good luck
Blackys right mate. Just make sure the two prongs are barbless.
Fricken stupid rule. You puncture the fish it gets off due to no barbs and then probably will die a slow death. Add this to all the other great scientific based rules eg blue groper, ab limit, etc
