+1 to the suggestion to get a Backscatter MF-2. The Inon 330 is just not well suited for a Snoot. I tried the 10bar snoot and it was terrible. You will be 10 times happier with the MF-2 Snoot combo, and you'll have a spare strobe as well. I pretty much always pair the MF-2 Snoot with a larger strobe like the 330, which acts as a fill light on low power.

You should leave it on the boat but occasionally I'll forget to take it off and I'll just stick it in my dry suit pocket. if you don't have a pocket you can always get something like tech shorts that include large pockets for wetsuit diving.

Don't buy that. Use a standard stainless steel bolt snap.

Novus #1 is just a cleaner. It is a finish only with no abrasives, per the product info below. Just don't rub too hard with your microfiber. SAFE & GENTLE: Contains no abrasive chemicals, ensuring a greaseless, anti-static shine that resists fingerprints and smudges while protecting your surfaces from further damage. Perfect for regular maintenance.

Novus 1 and a very clean microfiber cloth should clean it on the inside.

Check it all. Carry on the batteries and camera body & lenses.

You should spec out an ideal system for you X-T3 and the prices you found. Perhaps there will be some ideas for substitutions or improvement.

You made some beautiful and unique images! Very inspiring. I have a buddy that is really into manual focus prime lenses, Lensbaby 56 & 28mm. I was able to design and 3d print a set of focus gears for his lenses in a Nauticam housing. It's made using his lenses a lot more practical. You are still restricted to a pre-set aperture, but at least you have some freedom with focus. I had made a bunch of zoom gears for my Nauticam setup, so I had a good starting point. Some of these lenses "telescope" as you turn the zoom ring, so gear needs to be multi-part to allow for the motion. Nauticam Focus Ring for Lensbaby Velvet 56mm lens by AwkwardSwine - Thingiverse

See if your local library has one or if there is a maker space in the area.

Can you print a copy of the part for your strobe?

You can use the Nauticam trigger but it won't do TTL or HSS. You can to rapid fire at 30fps depending to power setting with the stock trigger. However, in the Nauticam Sony housings they don't provide a trigger like they do with the Nikon model. I don't know why that is.

I know some folks have been waiting for the Sony TTL / HSS flash trigger from Backscatter for their line of strobes. I just today got an email announcing availability for this set of new triggers. It looks like they have configurations for Nauticam and non-nauticam housings, and both sony and olympus options.

Head up to BC and you'll find some of the World's best diving. If you ever want to give some local diving a try, let me know and I'll join you for a dive or two. Cheers, Dave

Agreed, I prefer a slightly negative rig. I don't want it floating in my face or trying to escape to the surface.

Sounds like he had the choice of which direction to go and was able to go back and retrieve the extra camera. That is not the case with many dive sites. You go where the current takes you, and even if you can go backwards, you might not find your camera in 5 feet of visibility. As I said, you can have a lot of freedom in calm clear waters. That is not what all scuba diving looks like. Even then you are one out-of-air or buoyancy emergency in your dive group from losing your camera.
