Tank Prices

If only we all could be "stuck" with a pair of 72's...the perfect casual doubles...or as a single, great for a quick dive while your buddy struggles with the size and weight of an AL 80....

<sighs>

All the best, James

Trust me, with my air consumption, a steel 72 is something not to be stuck with. I actually got a great deal on them, $50/ea. It almost seems to me that an individual's air consumption doesn't get better, their tanks just get bigger. Except for Claudette and her ability to dive with air trapped in a McDonalds straw,

Dude, this is all you need

Dude, this is all you need

Nearly the same gas, half the valves, one-third the knobs, half the Orings so half the additional failure points, no hassles in filling, easier to get on and off the boats, easier to stow and travel with to and from the dive sites, easier to get through the surf with...

The 130 is a much better choice over baby doubles.

I think I'll stick with single tank dives. I'm not that experienced thus far with diving but, doubles for recreational diving just seems illogical.

Yeah, but baby doubles are 12x cooler.

12 x 1/2 x 1/3 x 1/2 = 1 ... so, it's a wash

Billy, I'll give you $100 for those two tanks if you want to dump them.

It wasn't as good of a deal as I thought. It me $102 to have the tanks hydro'd and tumbled, so I'll probably sell them for $200 if I get rid of them Thats a whole nother issue.
Thanks for the offer.

Actually 1/2 the redundancy. One bad O-ring on a single and you are in trouble.
Doubles, you can lose a reg, an O-ring a hose etc. and still be OK.

Just the manifold O-rings are the single failure point.
and doubles are actually pretty nice in the surf zone (unless you fall, and then you are in trouble)

So if you dive with doubles you need another reg, more o-rings and hoses? Do you dive with doubles?

I'm looking at getting a bigger tank, right now I'm stuck with a pair of Steel 72's. So I'm exploring HP and LP. At one shop, a Worthington X-130 High Pressure - 3442 psi is going for $399 and a XSScuba LP 121 Steel Tank is going for $398 Why would they be the same price? It seems to me that the bigger HP tank should be more expensive. Is there a downfall to HP tanks besides not being able to get full PSI fills at some places?

Thanks!

Billy

First off I see you only have about 12 dives. Most new divers think they need a bigger tank but don't worry your air usage will improve over time. I have a larger tank and it's anoying to always end a dive with 1200 PSI in the tank. I could have used a smaler tank and ssaved the effort of lugging that water heat throught the surf and up and down the big hill. In time you will value those steel 72 tanks. Ok, use a 100 cu ft tank for now but rememebr you will not be needing so much air this time next year.
If you look at two 100 cu ft tanks one ratted at 2400 psi the other at 3442. You will see that the LP tank is HUGE. It would be 26" tall by 8" diameter and the 3442 tank is 24x7.25 So you pay for either a big tabk or a small tank made with stronger, higher quality steel. Ok that explains why the price might be the same buy why whould anyone buy the LP tank?

1) the HP tanks are (were?) in short supply. So no choise for almost a year you could not get a 3442psi tank

2) You can't get a 3442 fill on many boats

3) LP tanks are easier on you regulator. I have my doubts about this but that's the story.

Most diver I know like the new style 3442psi tanks, you can anys under fill an HP tank if you want an LP tank but the other way around is not good.

I didn't think so. I hope not. It'd be like a collision between a Miata and a guy's car.

Moving to doubles is a money pit if you're going to remain a recreational diver. Although I don't know my man, Billy - I surmised he (like me) is a recreational weenie. It adds up fast:

* Doubles Training - serious training is real dollars.

* Another First Stage

* Bands, Manifold

* Likely a new BC. At the very worst, another wing

OY - enough already! eBay those estate sale hot dogs from the Carter Administration, get over the overrated nostalgia of diving these Mike Nelson throwbacks and get a new 130.

All of your tank issues (whether they be severe hooverism, end of dive floatyness, rigging, trim, gas volume, etc.) will be solved.

I'm no hercules, and they haven't made the SoCal shore dive I can't take my 130 on yet. I mean short of scaling down a mountain, there isn't any reasonable site I haven't taken this thing on.
