Subject: SV: Poseidon 2nd stages?
Date: Mon, 7 Feb 2000 14:38:56 +0100
We use the Scubapro G-250 and G-500 with the Scubapro MK-18 first stage.
This set up has worked great for us, the new mk18 1st stage is really good
for cold water.

Although i live in Sweden and Poseidon is manufactured here i think they
suck. I have dived them for years so i have personal experience with them.

First of all you guys need to lose the mentality that a rgulator must be
run at jet engine starting pressures - this is bullshit. Run the IP at
120 and nothing will freeze. Secondly , a G250 is more of a deco reg,
and if used as a primary must be detuned at the orrifice at any water
temp.

Regs need to be able to be taken apart underwater to clear the mushroom
valve. This is not possible with a Poseiden. They must be
interchangeable on all hoses and bottles - not a chance with a Poseiden.
They must be downstream valves, not upstream - a ridiculous problem with
the Odin. They must not fill full of water when scootering or in a
current - a big problem with a Poseiden due to the shower head with the
bullshit holes all around it. They must not stay full of water when you
pass them off in an emergency - the Poseiden is s death sentence if not
properly purged WHILE passing and breathing until sealed at the lips.

Basicly, you have to me a complete idiot or dive shop victim to buy
something that reaquires special hoses and fittings, a total moron to
buy a reg with an upstream valve and opv built into the hose or reg
(unless it is an argon reg, and then you got screwed if you bought a
Posieden because the seats are crap), and a card-carrying stroke to buy
any reg that requires 180 psi IP to operate like the cheap version of
the Poseiden.

Ask the Swedish Brothers what they use - they live in Sweden, they dive
cold water, and they do not use Poseiden. Gee, I wonder why? Diving
above the Artic Cirle, but then I guess that does not count.

Ignorance is the enemy of us all, and it is the life blood of the dive
industry.
