Advice on buying twin 10's

I have no intention of just jumping in the water without some training
on twins.. Now to the point. I could do a twin set fundamentals course,
but this is all extra cost, not to sure how much however I’m sure it has
to be the best way to go. Does anyone know what this course covers and
the duration; also is it a recognised course of just best practice. On
the other hand should I get a mate to spend lots of time in somewhere
like horsea with me.. I will add I am not planning to go down the
technical path the only reason I want twin 10’s is redundancy and when
using Nitrox I will run out of bottom time before I run out of gas (I
hope). What are your views on the transition from single to twins.

My view is that I have twin Faber 10's with an MDE manifold that I no
longer use. They are for sale if you are interested.

Huh? I did. Bolted to a scubapro jacket and sure as heck I could
not do a shutdown so the whole sorry story stated from there...
There's even a picture UKRS#4... look manifold at the top!

Twinset fundamentals? There's the DIR one and then there's Frank.
Other things cover it as either an assumption or as a incidental.
Once you have the plumbing set up the only new thing is the shutdown
drill and you just practice that whenever you've got a free couple
of minutes. I suppose I ought to try and drum up some trade for Frank
as he's promised I can get in on one of his 'Twinset-F' courses and
he'll show me how to do a helicopter turn... but then again I could
just be rude about him as normal.

One afternoon and it should all be pat. Nothing is hard. Well other
than dragging the things about for a fill.

Stop right there. This is Denial. Yes we know you don't want to do
technical. None of us do. But your diving always needs another 5 meters
depth to do the next wreck and then you just need another five minutes
bottom time to really do it justice. It's a slippery slope that ends up
with you buying the waterproof edition of 'War & Peace' to read on stops.

You must be mad. Don't do it.

That's why I put the course together, It is the relevant parts of the DIR-F
course, which in turn is based on the IANTD skills from Deep/Adv Nitrox.

The Twin-F is essentially a try-before-you buy to explain why some kit is
head and shoulders above others, configuring your gear with you, so you have
a balanced rig and going through the skills required to dive a set safely -
including how to route and deploy your long hose

It isn't the same as DIR-F because I don't go through DIR - If you want
that, I would recommend that you book a course with Andy Kerslake - he runs
a fantastic course. If you do DIF-F in a twinset then, all the practical
skills are the same.

Frog Kicks, Modified Frog Kicks, Modified Flutter Kicks, Centre Of Gravity
Exercises, Backwards Finning, Helicopter Turns, S-Drills, Valve Drills, 1
Minute Per Metre Ascents, OOA Horizontal Ascents and DSMB/lift bag
deployments.

Advice on buying 10's - don't - buy Hydrotec (no beaver or go dive) Faber
12l Talls, a ScubaPro 7" manifold, and some decent SS bands either from
Runningmede dive or Aleutian (I have some stocked if they run short)

Better still - I have twin 12's and twin 10's for sale.......

I put mine (2x twin 12's 300bar & 2x7L side-mounts) all out-of-test (or
nearly out of test) on the ukdiving web-site and asked for best offers. It
took 10 mins to get 3 offers. I sold the twins for £275 each (delivered)
and the 7's for £80 each (collected).

Cylinders are easy to sell. Come to think of it I also sold 2 OMS-double
100lbs wings & plates for £350 each in the same sort of time frame.

Cheers
Matt.

Look, look, me on independant twins...

Interesting question - however I wouldn't want start a debate over 300's &
bungees . They are obviously very popular - they sold very quickly for
top-dollar dough.

On the other hand should I ever buy any more OC kit then I would buy a
single bladder wing. I bought the double to deal with diving a wet-suit,
but that's not often enough to warrent buying a double for me. OMS wings
are excellent bits of kit - I had 2 sets and no issues with either.

However, with no weight-belt meaning less back-ache and a lower profile that
15's with near-same volume means that I would buy 300's again. I never had
issue with fills, and tmx to 340bar never bent me. There may be less gas
due to compressability, but in practice this simply isn't noticable.

Cheers
Matt.

Same old fins though, and the suit looks similar, although without the
large dollops of aquasure, screwdriver melt marks etc.

Cheers,
