Wanted Underwater cell phone housing

[tkdcol]

I'm looking to buy a cheap used cellphone housing for an older (also read cheap) smartphone. It's for a project to try to make an underwater monitor for a gopro. If you have the cellphone that matches, even better

Keep in mind a wireless wi-fi or Bluetooth monitor isn't a viable option underwater: Does GoPro Wifi Work Underwater? GoPro Tips & Tricks

(Note: dive computer air integrated wireless transmitters are totally different to be able to work underwater: 2.4GHz is useless underwater, for comparison 38kHz is what Shearwater SWIFT Air Integrated transmitters use and my understanding is below 10kHz would conceptually be even better underwater..).

You can use coaxial cable to transmit a wifi signal underwater.

Fair enough, I'm glad you were already thinking wired
(I was assuming "Wireless" Fidelity meaning "not wired," but given "Stainless" Steel just rusts "less," "wired wi-fi" is fine..)

The initial plan was "wired wifi", but I recently found some gopro cases that have a bulk head in them. So the new plan is just to hardwire the monitor with a micro hdmi cable. And change the cellphone for a slightly larger LCD screen en encapsulated in a polycarbonate casing
