Steel 120's

[Barnaby'sDad]

Most divers are unaware of larger tank options and for whatever reason, shops don't blatantly offer them.

Aldora is an exception.

$$$ For the average operator that caters primarily to recreational vacation divers, I doubt very much it would pay off to have a bunch of tank options. Most shops that I've heard of that offer different tank options are pretty clear about that on their rental page.

For operators that cater to experienced divers that aren't looking for a hand-holding operator, it might be a good idea to consider stocking some HP100's and HP120's.

It's hard for me to believe that most divers are not aware that larger tanks exist, and Sloeber (a dive shop owner, I believe) said that for his operation the demand for 120's isn't enough to justify the extra expense and maintenance that steel tanks require.

Dear Henry,

Are those HP tanks?

Dave Dillehay

Yes, they are.

I think most divers are aware of larger tank options. 120's are okay but 90% of the time I prefer the 80's. I get an hour or so dive on 80's which works just fine for me, I'll just do a couple extra dives if I want more underwater time. I hope that the dive shops operate as they are with 80's being the standard and offer 120's as an exception otherwise it will just drive the overall diving prices up and probably have more 'vacation' diver visiting the chamber.

Are those primary or secondary 40s?

is Aico the name of the company run by the Stathis person?

We use the 40's mostly for pool training so as to not damage our training pool tile. We also use them as ponies for our Deep Diver cert classes. That's about it, although they have come in handy for a few 10-12yo's.

Yes, Aico is the name of the other fill shop owned by Statis Themelidis.

Hi Henry,

I don't need 120's to make 90 minute dives but some divers do. That's the beauty of having choices. Scuba cylinders are not one size fits all. When divers need more air, we have the tanks available to them. We offer 120 as a rental through Aico and we own 100, 80, 60, and even 40's.

OK, so I have a better than average RMV @ 0.36 cu ft/min. I could do a 1 hour dive at an average depth of 66 ft with an AL80 and surface with just under 500 psi. Are your average divers better than this, are you? Of course, ndl comes into play.

Yes @scubadada, this 55yr old welder, 35 yrs of cigarettes and stuff (no cigs for 5 yrs now) can manage an hour avging 66ft.
IF we are still talking warm water and slow.

An hour on an 80 is pretty easy to do...100 minutes on a 120 and surfacing with 1000 psi is also easy to do...I prefer the later

I would be surprised if many on your clients could do this.

Obviously, depends on the depth...
