How can I use a smart phone with 100ft wired external GPS anttenna to use underwater. As side form the water prooffing which I have firgured out. I am looking to float a gps anttenna on the surface and use a chart plotter on a smart phone while scuba diving to locate wrecks and reefs off shore. As you know GPS sgnial does not travel underwater so need a wired surface antenna. What do you think?
