...Heck I've never even seen a frog spear in real life!...
I have been seeing them all my life... I just didn't know they call them frog spears! Somehow I thought that guys in USA would just blast them with .50 caliber sniper rifle... you save a lot of time not picking up the dead bodies!
Ok ok, just kidding. Here they are sold usually with spear fishing equipment. When I started spearfishing there were some kids whose parent's didn't trust them with a spear gun and just got them one of those. They just got some octopus, maybe squids and some "flat fish" (you know, the ones that swim close to the bottom and blend with the sand and stuff... I don't know how do you call them). Anything faster than that was impossible to get.
