In Europe we have this 10½ pound steel back plate. https://www.deepstop.de/en/backplates/1130-heser-backplate-long.html See above. You could also carry a 300 bar (~300 atm) steel tank. That would help you a lot.

True. You will become familiar with the basic principles. It also drastically affects the buoyancy change per foot of water in the shallows. Maintaining neutral buoyancy at shallow depth with thick undergarments (or a lot of free air) becomes much more difficult. And please remember that...

Good manual! Yes, the free air volume can become a problem (or a fun challenge... it depends on how you look at life). Air does provide good insulation, but if it is all in one place and nowhere else, then it does not help. I just hate shrink wrapping myself. Just a preference. Choose yours, and...

You need to train with all those undergarments and woollen socks and clumsy gloves and all. You can do it on the course, or you can do it later, but it will takes a few dozen dives to become proficient. Lots of undergarments mean a lot of air and hence great changes in buoyancy Less...

I will tell you a big secret. All commercially available regulators will deliver adequate air. Some will be big, some small, some black, some silver, some heavy, some light (and expensive). So many options. Even the historical ones do work in most cases. Just make sure you can service the reg or...

Btw, is it possible to download the divelogs from that BT to a computer?

Why Florida? You have plenty of water in Georgia. I don't know about the visibility, but hey, there will be life in the water. Only if you attach the pressure sensor to the rental gear (possibly removing the analog SPG temporarily first). Totally possible, but what a hassle! Using an analog...

Devil gas Manifold vs. independent doubles DIR wars What's next? This is what we get in a certificate based hobby. If only people would consider context and focus on attitude and procedures more than on nuts and bolts...

If I were you, I'd try the historical diving forums.

Great idea. I have access to one...

Strange. Are these tank valves of the old V shape that you need to seal with isolation tape and not with an o-ring?

Some possible reasons: 1. The LDS does not offer the type of tank/tanks that you prefer. You might want them smaller, larger, longer, shorter, lighter, heavier, concave bottom, convex bottom, doubles, sidemounted, steel etc. If you dive with a basic Al80 backmounted, then the LDS will serve you...

Alternate air sources are not needed at 15 feet. It is safer to just resurface. One true risk remains though: it is harder to rescue an unconscious diver who does not wear a BCD. This small risk is not much different from the risk people take getting drunk in a bar. The righteous will disagree...

I have mostly used a moisture wicking base layer for comfort but some times, when I feel lazy, and the water is a bit warmer, I have used just a t-shirt and underpants. In very cold water and for extended exposure I'd replace the moisture wicking base layer with merino wool. Washing just the...

Diving without an octo and without a bcd in warm +21C water. Depth varied between 1 and 6 meters or 3 and 18 feet.

A trilaminate drysuit will not keep you warm. You need to wear warm clothes (including warm socks) underneath. Pick your favorite. There may be many options to choose from at a diveshop but you could also just use plain old-fashion wool and test if it works for you. There will be some...

True, because the pressure inside the hardhat dropped to 1 ATM because of the failure. The external pressure then forced the diver into the hardhat. The end result was kinda messy. I've even heard tales of divers exiting through the air hose. Nope. Cannot happen. The drysuit is not connected to...

Your breathing capacity would be maybe 30 % but not zero. This is widely experimentally proven in squeeze training/competitions in caving where people actually breathe (laborously) without being able to expand their chest. Enough to survive, enough to cause panic in the uninitiated.

So, it will be tight to the skin, but it will not crush you (because you are not compressible, as you said). The suit will be VERY tight, but it will only become a second skin.
