<font color='#000F22'>I'm fairly new to this twins thing and I have got arms like a gorrilla.

But I've had no shutdown probs so far.

I think this is down to a few things:-

1. I swim a lot so I keep flexibility in the shoulder girdle
2. I always stretch out after every swim - usually in the jacuzzi!!!!!!
3. I've been doing shutsdowns/switch-ons with singles for a long time.

If you can do it with a single then twins are easier so next time yer in the pool just spend ten minutes reaching behind and shutting on and off without adjusting the harness.

Also relax whilst your doing it. If you tense up there's no way you can stretch easily. (oo-err missus)

Just a thought.

<font color='#0000FF'>Darlodiver, I can indeed confirm that Gav is blessed with extra long arms, unlike myself - hence my twinverts setup.

Bren , re time slot for the course, anytime suits me really, got a few plans in the pipeline for trips etc so I guess it'd be wise to sort out the DP course before anything else to avoid clashes.

Gav, DAve, you wanna hook up to do the course together? any preferences etc re dates? AIUI you do the theory seperate to the diving so would probably involve either a full weekend or 1-3 seperate days.

My immediate thoughts would be sometime later this month or anytime next month, give us time to sort out arrangements with Andy and &nbsp;genning up on the reading material etc

Bren - if you have to loosen your harness then you have to loosen your harness - there are no style points awarded in this one. Its 'Can you do It' and not 'How did you do it' that counts.

From todays dive, I can thoroughly recommend you beg, borrow or steal a 7l stage and dive with it to get your weight right and get used to having it as part of your kit. My trim went all to cock and I was grossly over-weighted this afternoon - again, I need to find my best config for stage diving long before I attempt the course.

Oh, and speak to Andy about the skill sets HE will be running! You just KNOW he's gonna make you earn that badge.

Here here, no points for style.

If u can do it anyway possible, its safe.. if you cant your basically diving a big, un redundent single.. bollocks to that.

Not that I know owt but anyway!!

Lets not even talk about your face, eh?

<font color='#000F22'>My M8 used three slob knobs for his trimix course

Honistly I am not kidding one on each valve.

And he passed??

He is a good diver as well but finds reaching he center valve impossable. As he said he relies on the one remaining tank after isolation and his loyal buddy (his wife) to get him up and he is talking about from 50m plus as thats all he and his wife do.

Deco procedures was an interesting course from a dive planning point of view but I was dissapointed it didnt go into stage use. If you can hold stops at set depths do horizontal hangs and keep a close eye on your computer / bottom timer its easy diving. Lern / re lern all the gas signels to indicate remaining gas and the hand signels for stops etc.

I had to do shutdowns at 36m on air so the added nark factor comes into play if it affects you at these depths.

I only did it as a steping stone to Trimix but it was an enjoyable course. The course would have real meening for people who have done Advanced Nitrox but dont want to go Trimix if it included rich deco mix using stages.

I did quite a few air or leen Nitrox dives with rich deco to increse bottom time or safety factor, prior to going Trimix but there dosent appear to be a course that covers this sector of diving adiquatly.

Have fun
