Reduce Reuse Recycle Repurpose
Way back in time (before surf leashes) body surfing wasn't considered such an off shoot from the surfing tree. Everyone lost their board at some point and everyone would body surf in. If the waves were good for body surfing you would leave your board on the beach and whomp. It was all surfing.
Some with some withoutWhile leashes did open up some spots that were too rocky to surf for the average surfer, the really good guys were already surfing there because they didn't lose there boards like the rest of us. So what leashes really did was to open the last few good spots to the crowds
No one trusted leashes in big surf for a while. The early leashes were made of stretchy surgical tubing attached to a suction cup on the nose of your board, the other end went around your wrist. When you lost your board the wave would pull it and then it would come flying back at you! Nose first. There were injuries. It was kind of cool to pull the nose of your board around when doing an off the lip etc. Oh and contests didn't allow the new device for a while. It was considered cheating. When the new ankle leashes came out everyone drilled a hole in their fins to attach it to. Leash plugs hadn't been invented yet. (I don't know where you attached your GoPro)
One of the things I really like about the mat is that it is leash free. I can go for months and not lose it then lose my mat three times in a day. Since I'm already wearing fins it's just an opportunity to whomp. But sometimes I will just float around and watch the waves. Lately I have even traded the mat for a handplane or just a bigger pair of fins. Bodysurfing is perfect for some on shore close outs.
