Granted PH I did enjoy your TopGun reference but be fair we are all intitled to make BAD jokes :-)

Ahhh well you they have even made a sytem for lets just say movement challenged folk with there new Cinch system which is supprisingly good.

So when is the first annual FUJAk beach volleyball championship? I'm pretty sure PH is volenteering for the sunscreen applicator position haha

really??

if set up proporly they offer what I would consider far superior hose routing due to there fifth port on the bottom and the swivel turrent
That is the mk25 anyway.

but each to there own,

Internally the mk17 and the apexDS4 are very similar but i do beleive (dont quote me on this though) that the Mk17's maximum flow rate is still a bit higher, but neither come close to the flow rate of the mk25

im a Scubapro man :-)

The New H regs are:

Halcyon H-75P = Scubapro Mk25
Halcyon H-50D = Scubapro MK17
Halcyon Halo = Scubapro G250V
Halcyon Aura = Scubapro R380 (an old SP reg which has since been superseded by the R395)

The Scubapro rep was telling me about them a while ago, but was keen to see what they look like, Prices are pretty good (supprisenly)
Acctually cheaper then SP but SP are bringing theres down to match i believe

I dont mind the look of the halcyon first stages but reakon the SP second stages look better

HAHA

I tought this random Norwegian Bloke to dive a year or so ago and he was obsessed with that bloody thing.
Very odd dude haHA

Sorry i was acctually refering to a staged cylinder. ie a cylinder to extend bottom time

When i say accurate i mean that the spgs (1inch face) ones i've seen are i dont know maybe accurate to like 20bar, not that there not accurate just hard to read due to size.

I plan my dives and dive my plans. and im well aware of my gas and my gas consumption but to me the bonus of having a slightly smaller spg i dont see the benifit outways the lack of distinguishable pressure

XS Scuba bought the rights to luxfer tanks and have scuba tanks are once again being constructed however they only make limited models now. I beleive these to be 207bar 40s and 80s (the ones we all want) and also i think 240bar "neutral ally'(the ones we dont want and i think some fiberglass or carbon fibre wrapped 300bar one.

The Australian distributer is still Aquanaut (aqualung) as far a i know and i believe all are now availible

hope this helps, id be curious how the hymarks ride

hmmmm. we def have the fizzy coke but i dont know about the antifizz agent, mostly just beer. But i reakon that if you wanna supply your own antifizz i could make sure it gets where it needs to be 

There are a few posts here that demonstrate an inability to plan dives. There is no need to look at a bottom stage SPG on a dive (different on a cave dive where the cylinder is NOT a bottom stage, it is a staged cylinder). LEARN your cylinders. LEARN how long they last at certain depths.

All you need to do is analyse and confirm starting gas pressure prior to jumping in the water. 220 bar. in an 11L bottom stage, at 70m that is 18mins for me. Don't look at the SPG. When it sucks dead, switch to BG. I want to get as much gas out of my bottom stage as possible, which means I'm going to empty it. Why they heck would I worry about looking at the SPG on the dive ?

Same with deco cylinders. Why do you need to check the SPG ? You should know that you have enough gas for your planned deco (and 1.5 times for reserve ) before you jump in the water. Again, no need to check the SPG during the deco (there is when you deploy the hose though), as you know you have enough gas for it.  

For a cave dive, if you're using half +15, then you basically hit around 120bar on the stage, drop it and pick it up on the way home. +/-5-10bar isn't going to be an issue (especially given that if you are using stages, you have redundancy in the back gas anyway).

Learn your dive time and depth, you can approximate tank pressures from known use. SPGs are only an AID to an effective dive plan.... but I am sure that you would have covered all this on your TDI seal-team bubble blower trimix program huh ? (fire in the hole... ).

PH, can you tell me from your real world trimix diving experience your thoughts on the above ?  (more stirring on this forum than an episode of My Kitchen Rules)

Seriously Ian just coz i like an acurate SPG doesnt mean i can't plan a dive.
Anyway ive given my 2c about these little guages for what its worth (apperntly not much though  )

What can i say im a Uni bum!

You feeling left out rick?

Not accurate enough for my liking, prob ok for deco bottles but wouldnt want to use them where more precise readings are needed such as bottom stages

my 2c

I really dont find the hose to be that much of an issue. those litle 6inch milflex hp hoses look pretty good, havnt used one myself yet

If you ask them you can get the valves upgraded to din/yoke valves, think it cost around $30 bucks
