| Quentinb (South Africa) Anti Shark Surfboards I don't know if something like this already exists as I am not a surfer, but I was thinking why not put something on the surfboard to warn the surfer that a large fish/shark is close or even better to repel the shark. Some small sensor based thing with a rechargeable battery. Reward: Whatever you feel like giving me, I really don't care. I am not a surfer so a device will not benefit me. |
