[Closed] Any (GoPro) scuba divers out there?

Hello. Basically, I'm going to Kenya to work on a school, climb Mount Kenya etc 😉 . However, I'll also be doing some scuba diving and I'm interested in trying to do some filming with my GoPro. I know the camera needs a special lense / case to allow it to focus well underwater but I can't justify buying one for one trip. So, does anyone have one spare that I could borrow? I'd be happy to pay extra for any trouble.

Thanks in advance.
