I switched to Nauticam because they were the first to release a housing for the Canon 1DXMK1.
While many other companies didn't even bother making one at all. Solid built quality, great customer service and a great line of accessories.
Once on location I use the CineBags Square Grouper to carry, transport, and protect my underwater housing. It can be filled with water so I have my personal rinse tank on the boat.
Maybe not as well known as Pelican cases I use a HPRC 2700w case for my carry-on. It is technically a little too big to be legal carry-on size but it fits in most standard sized overhead bins e.g 737 or larger. The cases are much lighter than the Pelican cases and have some nice large handles on the top and on the side.
I love the narrow and strong light output of the INON. I use it as a focus light, a snoot, and a dive flashlight, all depends on the dive. I prefer it due to its high built quality and the fact I can use small AA batteries.
May favorite bag, ever. Love the color option and I must have at least half a dozen of these bags. I combine them the the MIJI packing cubes so my stuff is not getting lost in a big black hole.
Reef Photo and Video in Fort Lauderdale, FL is my goto dealer for all my underwater photography needs. Excellent customer service paired with knowledgable staff is always a winning combination.
I protect my rather expensive 230 Zen Underwater port in the CineBags CB71 Jumbo Dome port case made from heavy duty tarpaulin fabric. It holds my port, spare port cover, o-ring grease and a spare o-ring. It's like a packing cube for underwater photographers.
I use the CineBags CB76 Tool Kit to keep all my spare parts, tools, and everything maintenance organized. Its made from heavy duty tarpaulin, has a neoprene handle and 4 see through mesh
My dopp kit is the CineBags CB91 Location Pack. Two big main compartments for my main toiletry stuff, and two smaller zipped pouches built into the side walls for spare contact lenses and other small stuff.
The CineBags CB27 Lens Smuggler was designed to look like a laptop bag so it counts as a "personal" item and not a carry on. I slide it with the trolley leave over my rolling hardcore and can bring a ton of gear with me into he cabin.
