Not so much lying on the bottom, but suspended a bit up from the bottom by all those danglies...
Agreed absolutely 100%. The purpose of this dive, which wasn't conducted without prior research and understanding, was to wet check the unit before flying out to Gran Canaria for Mod1. I would not be happy to get all the way out there to find a £2.50 widget was faulty etc. Dive 1 got canned very quickly when a buddy spotted a pin-prick leak on the unit. Dive's 2 and 3 went well.
I put the piccy up deliberately to draw attention to the point you make, appreciating there will be a bit of banter alongside it. The day re-enforced two points:
1. Never skip a bubble check.
2. Never assume your buddy will spot and do something about what would be the bleedin' obvious to 99% of other divers Dom you're sacked, I want Leighton for my new man servant.
The only danglies are two pressure gauges that were supplied on extra long hoses for ease of checking. Jury's out on whether I keep them.
how do you get on with the inflator on the outside of the loop?
Still sorting best position. Not tried it on the inside yet. Next dive had it bungeed down better on the outside and closer to the CL. Found it very easy to get to then. It's a pull dump as well, so bouyancy adjustments were very quick plus I have the DIR position for my Seaskin autodump, which also allowed very quick changes.
At bloody last!
yeah-theres a lot of stuff that needs to be stowed.
no right or wrong way i guess just what works for you.
i tried long and short hoses for the spg's-went for short in the end but the long ones worked ok when i routed them on the outside and clipped them off like oc tech.
Are your short hoses on the inside or out? The KT handle seems good for runnning stuff through and keeping it all in place.
I don't like the suit inflate running off the bail-out; another hose to get in the way. I have a KT stand, which my 1.5ltr bottle fits inside.
Hp hoses run down the inside of the counter lungs.
Suit inflate runs off a 1.5 cylinder mounted on the back plate.
Running the loop through the lift bar puts a large kink and increases your WOB.
Only point I felt qualified to comment on. I guess bungie them up if you want them that long.
Can we have a matching picture of BK to see how he has it rigged?
How about a spec of your unit Major, or confirmation that it matches BK's rig.
Not entirely sure that RB's are the whole of the future, I've been holding out for the Tom Smith version, with O2 by electrolysis from water, and a cryo scrubber. May be a few years yet...
I'm guessing that bubble free is only relative, buoyancy must dump as you ascend, and doesn't the counter lung as well ?
It's a closed circuit, to dump air from the loop and counter lungs you breath out of your nose I think
Yep, air dumped through nose and over pressure valve. It's also something I realized I was doing on occassion when neutral and will have to stop it. I dumped gas most the way around while I was toying with bouyancy control and still only used 30 bar on each 3 litre.
Don't know if they're the thing of the future but I enjoyed breathing warmer moist loop gas with no discernible work of breath and if I felt like a big gasp, just increasing loop volume. I also like the good run times out of a 3 litre and diving optimum nitrox. Pros and cons as with all...

How much was your unit Major?
£4.3k including halcyon b/p and Explorer wing, now both sold. Didn't include the KT stand.
You know you've done the right amount of drills when the O2 injector sticks open at 55m and you think "shit happens" as you deal with it...
Poseidon mk6 about 30 hrs so far and loving it
