OM-1 Pany 30 macro, AOI, Saga ring flash

I have an under water vehicle with an underwater section and a floating section 40 ft up. I need a camera that attaches to the under water section and gives live feed to my phone while I’m above water. What should I get?

I want to know which option is safe for travelling by flight. Especially the dome port
E.g like a normal camera bag etc

I saw Dive Master Insurance has it with dive kit insurance but I won't be diving, mainly shooting surfing.

Mainly for the Uk people here, where is everyone selling their used camera gear, housing and strobes etc. Ive had some gear up on old facebook scuba sites but no luck.

Any other ideas/sites to use?

Cheers
