Which specialized gear did Bill Carmody use to film his underwater adventures in Boracay?

Based on the available content, the videos from the Boracay shipwreck dives were filmed using a standard action camera in an underwater housing, likely mounted on a handheld rig. There is no mention of highly specialized cinema gear, lights, or scooters in those clips, and one video explicitly notes that no underwater lights or flashlights were used, emphasizing a simple, natural-light setup.

Are you thinking about what gear you should buy for your own first underwater videos?
