If going deep vent air from suit at surface then head down and swim for the bottom to make most of bottom time.......add a bit of air on way down to take of squeeze and cold.
Oh and def NOT head down on way up! LOL

Talking of ascending (not that we were 
) I have a real problem ascending horizontally (although I descend horizontally). I feel that I want to be vertical with the line in front of me. For some obscure reason I feel much less in control if I'm horizontal, even on the safety stop which I can hold with no problems but prefer to be vertical.
Why should this be?

dump all the gas off the primary wing, vertical body one fin in front one out the back acting as a rudder.... one hand constantly equalizing, 50m per min rate- bloody awesome!!!! takes a while to put the breaks on though.....

I always go down head first when in a wetsuit but I'm a bit cautious in a drysuit, having seen one diver do a rapid feet-first ascent when his suit inflation valve stuck. After the first six metres, watching to make sure my buddy is OK (usually my wife) and checking that all equipment is functioning correctly (no stray bubbles etc.) I tend to go down almost horizontal with a slight upward list in case of a malfunction.

Maybe you are keeping youself a little negative, and finning slightly to maintain position? This can feel safer as you feel like you might sink, butn not like you might ascend accidentally...Talking of ascending (not that we were

PS sorry didn't get to drop into Aquanauts and say hello at the weekend, ended up diving out of QAB instead due to the buggering around with the lock gates...

That sounds about right. Easy to put a bit more air in the wing if necessary, not so easy to stop a hurtle towards the surface from 5 metres
It's a real pain with the lock-gate at the moment....the clock is ticking on every ruddy dive so we get back in time.

I tend to point in the direction I'm going so, unless we've got the slack right on, it tends to start head down but end a bit horizontal. I swim down as sinking take way too long on the CCR unless we're doing enough deco to carry a couple of steel stages.
A head-down attitude seems to make you more prone to the narks.
Good exercise - descend horizontally, legs bent to stop air migration, then at the bottom pick up a second weightbelt.
Lay it on your back (open) and ascend again horizontally.
Do it right and the belt will stay in place, do it wrong ...
I believe it comes under CBL

... and yes, I have done it.

Mmmm, I really can't see the point in practicing horizontal ascents - that just seems like a way to get your head jammed up someone's Jacksy or worse. It is worth practising dumping air out of your suit cuffs or neck seal in a hurry.

Whatever feels good. That's a good way to go down.
exactly! but if equalisation is a problem for you: Divernet | All you need to know about earsWhatever feels good. That's a good way to go down.

For me, normally the freefall horizontal position. If my ears are a bit sticky, then head up to reduce the hydrostatic pressure on my eustachian tubes and kleep em open.

Would that be a proper 12" or a blokes 12 inches
Either way, you can get a much smugger effect if you manage it at 6inches.
(which is much better on a sandy bottom than an old wreck)
It's an "in and out" x 4 = 12"
