Poseidon Regs

Hi guys and girls,

Looking at purchasing some new regs for use with a manifold twin set
and wings. How do members of this group rate the Poseidon Jetstream
and Cyklon 5000 regs.
This is going to be my first purchase of equipment for use in
technical diving in the future. The wings and twin set on long-term
loan ;))

Any advice greatly appreciated

Mark

I've got a cyklon which I picked up second hand. When it is freshly
serviced and well maintained, it breathes very nicely (there is an
adjustment inside the mouthpiece which you can rotate to eliminate the
harsh breathe others may report).

OTOH, leave it without using it for a month or so and unless you are
very careful with your cleaning the metal bit that links the seat to the
orifice in the second stage sticks. Although this is simple to fix (just
give the bits a u/s bath and refit, retuning the reg as you go) it's not
a job you should attempt if you don't know what you're doing. My LDS did
it for free (they're good like that) but I imagine others would charge
you for a full service.

On balance, I think there are a lot of regs I prefer out there... some
of the lower spec scubapros and apeks might be better. I rate simple and
reliable over expensive and fiddly.

[For the record, I use a Mares Abyss as a primary, a scubapro mk II /
R380 for the secondary, a conshelf XIV for the stage and the poseidon is
a spare.]

Some love them, some hate them. They have always been favourites amongst
tekkies and especially cave divers, but can be rather high-maintenance.
Definitely try before you buy.

Andy (who has about 8 of them).

The reason for my interest in Posideon Regs, is the fact that the
regulator is non-keyed and can be used from both right and left side.

Are there any other types of regs out there that provide this
function.

Am using Apexs regs at the moment. These have never let me down, with
regard to freeflowing, etc, but cannot route the left hand cylinder
reg down the left hand side because the 2nd stage reg is fed from the
right.

Did find one on the net last night - The Oceanic Omega 2 2nd stage.
Can be used on both sides.

Anyone know the pros and cons on this regulator.

Cheers

Mark

May be you are looking at the wrong solution. Why do you need to
route down the left? Most people with twinsets route both regs to the
right.

Another that will give divided opinion, some love it some hate it, my
mate likes his but to me he always seems to be fiddling with them
whereas I pretty much ignore my Apeks regs

Until about 6 months ago, I dived almost exclusively on Omegas and I still
hold them in high regard. Some say that Oceanic regs are only good for warm
water diving but don't believe it - providing you get one of the
environmentally sealed first stages (the DX4 is by far the best) then the
Omega will happily function in high sediment/low temperature conditions. My
Omega's were routinely taken into 2 degree C waters thick with silt and
never once free flowed!

Personally I'm not a big fan of Poseidons as I honestly think they deliver
*too much* air. People argue that they're designed for 'deep air' diving but
you could, of course, argue that you shouldn't really be diving deep air in
the first place - if you're going to those depths, you should really be
looking at normoxic or even full trimix which doesn't need such a 'high
performance' reg in the first place! At the end of the day, though, you
makes your choice and pays yer money - give them and other brands a try and
buy what best suits you!

I had a pair of Cyclons (from new) and sold them after about one year.

Advantages:

Side-vent so not 'handed', not a problem if you route the hoses correctly

Disadvantages:

1. Non-standard hose fittings so more expensive & difficult to get and can't
swap with other brands of second stages.

2. Non-standard intermediate / second-stage pressure (1 to 2 BAR higher than
any other regulator), so a second-stage hose rupture or a freeflow will
empty cylinders quicker. Higher pressure was for 'deep-air' diving where
the air is thicker so needed a greater pressure to flow, a disadvantage when
using tri-mix as helium flows far easier than Nitrogen, so, conversely a
LOWER IP is required.

3. Regularly need 'tuning' to get best performance.

4. Expensive servicing, and finding a technician who knows Poseidon
correctly is not that easy.

5. Common problem of 1st stages is that the pressure relief valve (a little
hole on the body of the 1st stage) often leaks (sometimes cured by tapping
the 1st stage on the floor!).


I have now changed all my regs to Apeks without any of the above
disadvantages, and with the added bonus that they are so simple that I
service them myself.

I also had a Oceanic Omega 2nd stage and it constantly dribbled, even after
(at least) 4 trips to the LDS where it was bought new from.

Apeks still do a non handed reg, now called the Egress.

A buddy is considering one, so if anyone has experience of this reg I
would be glad to here it.

They breath fine if adjusted and serviced correctly
but after a while you get sick of adjusting them and
servicing them correctly every other week to stop
them free-flowing so you wind them up tight and they
breath stiff but don't dump your gas.

Normally filling a blob was enough to set it off and
you just had to shut the cylinder valve to shut it
up (and try to remember to open it again to inflate
the wing on the surface). What OC divers did with
the things I don't know as they needed to breath
occasionally.
