I would like to view video above water taken by a camera that is underwater. To do this I would need a tethered camera because WIFI does not go through water. Tethered video systems that work underwater tend to be super expensive. I'm looking for something under $100. I have a GoPro with a waterproof case and a WiFi addition to it. There is a hack to use capture the WiFi and then view it on a phone. I have been unable to make the hack work. If you have been able to do this or know of an inexpensive alternative, I would like to know.
