Hi,

I've been on this list for the past 2 weeks, reading the archives and
trying to learn about technical diving. It's a great resource and I wish
I'd read it before I spent some of the money I have on useless kit.  Now
I've got some specific questions and would welcome your advice.

I've been doing recreational diving for the past 2 years; I dive mainly
in the English Channel where I live, plus other parts of the UK and the
odd trip to the Red Sea. Although I'm not yet an advanced diver, I want
to get into tech diving and eventually dive some of the wrecks further
offshore in the 40m - 50m range.  As I haven't got the time to do as
much diving as I would like this isn't going to happen all at once; not
do I have the money to replace my kit all in one go. What I want to do
is to put together a Hogarthian rig in a modular way - when I buy kit
from now on I want it to be useable for whatever diving I end up doing.

I've decided to replace my regs now, but not to get doubles and wings
until next year. Meanwhile I'll continue to use my 15 litre single
cylinder (bulky, but I get 2 dives out of it without returning to shore
for a fill) and Buddy Profile jacket. I'm planning to buy ScubaPro
Mk20/G250 as my main reg, as I currently use a Scubapro Mk10/R190 and
it's always been brilliant. I would like advice on the following points
-

Should I get a 5m or a 7m long hose? This is for open water diving: I
don't ever plan to do deep wreck penetration. For a 7m hose how do I
stow the extra length when wearing a jacket rather than wings? Any
particular make of hose?

What about the backup reg - I've been told the ScubaPro Mk20/R380 is
fine.

Should I replace my tank valve and use two first stages? Or use one
first stage with the existing pillar valve? 

Can anyone recommend a good nitrox instructor on the South Coast of
England?

I think that's all, but if you think I should know anything else then go
ahead ...

Cheers and thanks,
Liz
