This bloke knows nothing!

All the above is untrue.  This subject has been done to death in previous
threads, however I will re-state some of the issues.

The fallacy that Poseidon regs are good at depth is perpetuated by idiots
who still like to do deep diving on air, rather than using the correct
gases, which actually need a LOWER interstage pressure as Helium gas does
not 'thicken-up' like high pressure Nitrogen, and, as much diving is still
done in the 0-40m range, why have a reg that does not perform smoothly in
this area?

For the last 10 years the Apeks range of regulators have not only been the
choice of the majority of new club divers across Britain & Europe, but also
the choice for ALL of the current deep diving record holders (including the
300m / 1000ft dive last year).   No Apeks regulator needs 'modifying'.

I have nine Apeks regs (TX40 to TX100), all are used regularly betwwen 5 and
55m depths, using gases up to 100% O2 and water as low a 2 degrees C and
have not been 'adjusted since their last service about a year ago (and a
couple of hundred dives).  I regularly check the interstage pressure and it
does not vary.

Poseidon regulators (of which I used to own two Cyclons), only have ONE
redeeming feature, that is that they are side-vented, i.e. not 'handed', a
matter of no consequence if your hoses are routed correctly; otherwise they
have significant issues compared with Apeks (or many other brands for that),
these issues include:

1.   Non-standard hose fittings, so if you are diving away from a Poseidon
dealer or service centre and a hose problem develops, tough, no spares!

2.   Non-standard intermediate pressure on Cyclon; using a higher than
standard medium pressure means that if you have a freeflow you will lose
your gas even faster and that you cannot 'borrow' a spare 2nd stage if yours
develops a fault!

3.   The new X-Stream uses a cartridge based 2nd stage so no adjustment
possible!

4.   The Cyclon goes 'out-of-tune' regularly & needs 'tweaking'.

5.  Cyclon and Jetstreams often give a 'wet breath' bloody inconvenient and
(if diving in the sea) not very nice, worse still in potentially polluted
waters (see coastlines around most major cities).

6.   The  Jetstream is a heap of crap and often freeflows (after it has
thrown the air down your throat using that 'servo-assisted' valve).

7.   Servicing is expensive (see points 1, 3 & 4) and very few places can do
a good service (even those who say they can).

8.  I've lost count of the number of times I see a Poseidon 1st stage bleed
valve dribbling.  This is often cured with a swift blow to the body of the
1st stage (tapping on deck of boat from 2 to 3 inches), however Apeks regs
don't need this treatment!

9.  Atomic regs are supposed to be good (they bloody ought to be at that
price), but are in many ways simply modified copies of older Scubapro
designs and are not that much better than any other current brand.

10. All current Apeks regs are dry-sealed so don't need a cold water kit.

11.  Don't buy any 'lightweight' regs as its a waste of money.  Lightweight
regs using Aluminium or Titanium alloy are NOT suitable for Nitrox (both
metals can oxidise or burn under certain conditions) and any weight you lose
on the reg material will need to be offset by more lead on your belt anyway!
