* Boots on AL80s.... the bottom is already flat. What gives?
They protect pool decks and tiles. Some pools won't let unprotected tanks in.

The rebreather helmet at DEMA was weird. Apparently there was an "incident" in the tryout pool, but no one would tell me what happened, only that they had to surface prematurely. Very prematurely.

However, these scare the crap out of me:

I have one of these. It works great. No dry mouth.

Well, do you feel particularly alert and invigorated by those negative ions? I too like waterfalls and forests . . .

I know nothing about that ion claim and don't care. It moisturizes the gas, that's the point.
 
"Negative Ions refresh, invigorate and increase alertness. The force of moisture through flow tube crushes water molecules which then attach to oxygen molecules to create negative ions.
Awesome! Now I know why I love coffee: the grinder crushes coffee bean molecules to create negative ions.
 
Anyone here recall the S.C.U.D.A, from the early 1990s? The so-called "self-contained underwater drinking apparatus," which allowed a diver to drink beverages -- ethanol-laced or not -- through a specialized mouthpiece; bag, and valve?

I recall guys from my Caribbean days, who would take drinks along while diving, either in knotted surgical gloves or even catheter bags; and would remove their regulator and bite the finger to obtain said drink. Haven't heard from any of them, since the close of the twentieth century -- can't imagine why . . .

I think you can find recent mentions on Scubaboard of members who bring juice boxes on dives.

Cuba libres among them?
 
I guess, since the Aqua Lung i3 system came out, Dacor's push button BC inflation / deflation was a precursor of the future, although I'm not a fan of either.

Not a fan of the i3 either.

I heard that some water got in the canisters the first day that helmet was tested in the tryout pool and the guy who was testing it was rushed to the hospital ... Which is why they were showing it the next day? ... really dicey if you ask me :)
