I am trying to get into spearfishing and can't speak from experiance, but still have advice. I am a bow hunter and have seen 3d carp targets. They are designed to take a thousands of hits from broad heads (imagine an arrow head with layers of razorblades). They anchor just below the surface and float steady, I'm sure you could just shorten the line. I figure one target would last a lifetime for a spearo.
