As a Free-diver and Spearfisherman, I am very careful selecting new gear as I am sensitive to any adjustments. The General Purpose Shark Shield unit made me a little unsure. In the water swimming with it, I was aware of it for the first 10-15 minutes. However, after some adjustments in my kicking I felt little difference. I deliberately dragged the General Purpose unit through stag-horn coral, caves and most every rough surface to see if it would get caught up, and in the last six months of regular diving I”ve had to reach back and unhook it twice. Its only 2m long.
Sure I notice it being there, its about the same drag as like a large knife on your leg. However, on the rare occasion when the men in grey suits turn up (sharks), I thank God its on there.
My thoughts on wearing the Shark Shield are similar to driving a car, “Why wait for a car crash to put your seat belt on?”
