^^ Snags, that didn't take long!
Seriously, if they work then anyone surfing, kiting or windsurfing in shark teritory should wear one
I have seen video of the trials for these wetsuits. They weren't allowed to use human shaped dummies, but they used drums filled with fish. The drums were plain, or covered with neoprene in these patterns. Sharks have poor visual resolution but good contrast recognition. This means they have trouble discriminating broken outlines. They mostly attack from below and the "prey" is outlined against the blue sky above. From below, a surfer on a board in a black wetsuit looks remarkably like a fat seal. Anyway, back to the experiment - the drums coated in the patterns confused the sharks. They swam up to them but did not bite them. It was like the shark knew there was something tasty there but couldn't quite see where it was. They attacked the plain drum. Research done At UWA by Shaun Collin
