Re:New equipment
I am definitely not against buying from the LDS, we want the local people to stay in business for sure. But sometimes a good deal is just hard to pass up. I plan on buying my primary equipment locally but if something good comes along and I can replace an older, secondary piece of gear with quality equipment without breaking the bank, its an easy decision. I just don't want to jump out of the frying pan and into the fire by thinking that something is a screaming deal when it is a lemon that no one can seem to fix, so they sell it on Ebay. Thanks for the tip on diveinn.com, it gives me an idea what the shop prices on some of these regs are right now. Later

Re:New equipment
OK Todd, I know we talked about this after the dive, but what did you breath to the surface? My Poseidon. Wink Anyway, that wasn't the greatest dive we've had. Good luck finding a different reg. I personally cant wait for Deep Blue to open. A dive shop on my way home from work! The only thing better would be not having to work.

Re:New equipment
You're right on that one Chris ;D, the mighty Odin lifted from the depths Big Grin!! I would have sucked air through about anything by that point. Fortunately, you are one of those people who have had no problems at all with their Poseidon. If I was in your position I would feel the same way. After a couple of failures I have lost quite a bit of trust in my Cyklon so I have decided to move on and try something else. Later

Re:New equipment
Hey Vtach, Chris - sorry to hear the dive didn't go so good after the ghost ships festival. Kind of makes me glad that I didn't drive back up home to get my gear and go with you guys ;D

Re:New equipment
They're posted under the "gear for sale section". They come with caps to break them apart and use as singles if you want to.

Re:New equipment
I am purchasing some PST tanks which use there new pressure rating. Basically, these tanks are low pressure steel tanks that can legally be loaded to 3400 psi versus the 2640 psi rating. They change the heat treating to get this rating.

Therefore the LP-95 that I now use and like a lot will be a E8-119 with about the same weight , within 2 pounds, and basically the same dimensions but I can legally load it to 3440 psi and have 119 scft of air.

I will be getting the E8-130, what is 3 more pounds.

Here is some other information. This can raise a lot of debate.

Doug

"PST Scuba introduces our latest scuba cylinder design called the E-series. The first scuba cylinder with a service pressure of 3442 psi to have a yoke/DIN valve capability. The E-Series incorporates our advanced cylinder technology found in our highly demanded AquaAire Sports Series. (C_C added note--E9791 HP cylinders)

The E-series combination of features can (sic) not be found in any other scuba cylinder. This cylinder offers excellent weight to volume ration benefits, and also has excellent size to volume ration benefits, plus negatively buoyant when empty, A design that when filled to 3442 psi will offer a diver a cylinder smaller than any other cylinder available. This same cylinder can be filled to lower fill pressures and still offer a diver a cylinder with great diving characteristics.

The new NRX valve offered on the E-series has a dual outlet capability. The valve can be used with either a yoke style regulator or a DIN style regulator. This valve is cleaned to CGA guidelines G-4.1 and can be used for nitrox gases.

The New E-series with sizes ranging from 52 to 149 cubic feet of gas with meet the needs of the beginning diver to the most advanced technical diver."

Ok...here is my commentary then on to the specs....These pressure ratings will apply only to NEW cylinders that are manufactured using the DOT Exemption E9791. This is the same DOT exemption that allowed PST to produce the HP 80, HP 100, and HP 120. This pressure rating will NOT apply to any cylinders produced under the DOT 3AA certification....this means no LP cylinders will/or can be rerated to the higher service pressure. To create the new service pressure cylinders, PST will use cylinder sizes similar to previous LP cylinders, but use E9791 alloy for the cylinder.


Examples include: E7-80 has size specs similar to those of LP 65s. Length is 19.75 inches, Diameter is 7.3 inches, Weight is 26 lbs without the valve and will hold 64 cf of gas at 2640psi, 72 cf of gas at 3000 psi, and 80 cf of gas at 3442 psi.

Here is a table of specs for each of the new cylinders:

Part # DOT Servise Water Water Diameter Length Weight Bouy Empty/Full
Spec Pressure Capacity Capacity Inches Inches Lbs. Lbs.
Cu. Inches Cu. Liters

E7-65 E9791 3442 psi 506 8.29 7.3 16.75 23.2 -1.5 / -6.4
E7-80 E9791 3442 psi 622 10.19 7.3 19.75 26.0 -1.5 / -7.5
E7-100 E9791 3442 psi 778 12.75 7.3 24.00 32.0 -1.3 / -8.8
E7-120 E9791 3442 psi 933 15.29 7.3 28.00 36.6 -1.3 / -10.3
E8-119 E9791 3442 psi 926 15.17 8.0 24.00 39.3 -0.5 / -9.5
E8-130 E9791 3442 psi 1013 16.60 8.0 25.56 42.2 -1.8 / -11.55
E8-149 E9791 3442 psi 1158 18.97 8.0 29.37 47.5 -1.8 / -12.9
LP-45 3AA 2640 psi 440 7.21 5.5 23.00 18.0 -0.5 / -3.9
LP-80 3AA 2640 psi 785 12.86 7.3 24.00 32.00 -1.0 / -7.0
MP-72 3AA 3300 psi 572 9.37 6.9 20.75 32.00 -6.0 / -11.4


Valves and Manifolds being sold with PST cylinders will be those manufactured/marketed by THERMO.
