GPS uses higher frequency than can travel underwater. Underwater communication is done using low frequency. That is why communications by submarines is generally done on the surface. High frequency waves are very close together and are easily disrupted penetrating water. Low or long waves can travel through water with limited range.hydroslyder:Does anybody know why they dont make an underwater GPS, I figured this would be something really kool, you would never have to worry about not finding a wreck, or the dive boat again.
Anyway just a thought.
Thanks
By the way. A waterproof GPS means if you drop it in the water or it is in the weather. Not that it can be used underwater.
