AIUI (could be utterly wrong) they DO empty their lungs - exhale thru nose to empty the counterlungs and hence become negative.

Either way, all the RB divers I've chatted to use suit for buoyancy, as their weight remains virtually constant during a dive.

A lot of us do a very inelegant duck dive to get down the first metre, the rest is fine.

I remember reading an article recently and the drag caused by gauges, ponies/stages, twin sets, torches etc was awful could the case around the box actually be better than all that other clutter. It might make an interesting project.

Someday I hope to get some fishing scales and a scooter or other source of constant speed and measure the drag of all these different bits & bobs - once and for all, I'll know if bungeed wings really ARE better or worse for drag than normal ones

But by the time you've finished using it for your BC (of course there are those who use drysuit for buoyancy) , flushing the loop perhaps and then replacing any gas in the loop used for mask clearing etc, there's not a lot left at 60 mtrs. Oh and then you have to breathe it from the air2 thing which then makes ascending a right pain as you need that umbilical for your ascent.
And that was my point. After the discussions I had with the chap who had one at the weekend he admitted it was the only weak link (as did another chap who uses on in the dive shop). My points were made with reference only to the inspiration.

I agree about the bouyancy thing, though. Most of the time they tend to use their drysuit for bouyancy and not use the BC which is integrated into the Inspiration.

If I ever dive a CCR in the future I will dive with a 7ltr 32% stage and a 100% drop tank on the boat. I dont think the CCR offers much benifit in the weight and kit clutter stakes and thats not the reason to get one.

My reasions for wanting one are:

Loads of gas available if you get into trouble.

No need for multiple twin sets for varieng mix depth dives

Gas saving once initial equipment cost is ignored

No Bubbles

Warm moist gas

Less hassle on multiple dive trips where you keep having to rush about lugging heavy kit for fills.

Some deco saving on shallower dives (but this is not a big issue)

Reasions I dont get one are:

Safety issues not resolved to my satisfaction

I lack the dicipline to dive the unit safley

Initial cost of the kit

Re lurning diving from scratch would be a pain.


Andrew and I thaught long and hard about it this year and we decided to go for it next year. I am hoping that the CO2 temperature moniter system is up and runing by then.

I like the kiss unit but I will get the Insperation as its UK bassed and IMHO ahead of the game technicly.

Bantam, you mentioned that you dived with an inspiration diver.  What bail out / AAS is available for the OC buddy of an Inspiration diver?

Sorry I know I am not Bantton but:

If the CCR diver is Alpinist, then &nbsp;some where between not a lot and bugger all.

You have on offer the same 3ltr bottle that he is using for his CCR.

The CCR chaps I dived with (Rob and Paul R Marks and Brad) were kind enough to have a stage of bail out gas with them. Rob had a 7 of 50% if i remember corectly and Paul and Brad had a seporate 3ltr of 20/30 or similar cliped to the side of his unit.

I think they all had conventional hose and reg for bail out.

the unit as standard you have the dilutant 3ltr bottle, admitatley may be only 2/3 full

most inspiration users i have talked to will carry an independant oc air supply, this being dependant on depth/expected decompression requirements, but minimum 3ltr pony

Good Question. Twinset or Pony?
