Ali Twins

[Air Guzzler]

Ok the title looks like another newbie question and in a way it is.
At the end of the month a few oddballs are off to the red sea for a weeks wreck diving & merryment.

As a few may know ive just started diving twin 12's with W&BP

my old BCD, 5mm semi dry & Ali 12 i had to use 11kg
in the uk with a W&BP and my dry suit i have 5kg

So how much weight should i be looking to be using with twin 12's

i dont want to be looking like a bridge nickers on her honeymoon by going up & down for the trip.

how about doing a weight check before the first dive?

Simple questions are never easy to answer.....

Very much depends on the bouyancy of your suits and cylinders but ....

the AL80's / 207 bar twinsets in my shed need 4 - 5kg more weight than 12L / 232 bar steel twinsets also in my shed.

Drysuit compared with wetsuit is almost impossible to answer - but 5kg would be a good place to start. So all in all no change! I suggest weighting as per normal and blobbing around in the shallows with an almost empty twin set until happy.

Everytime I dive somewhere warm and put on the wetsuit I am depressed just how heavy the Al cylinders are.

Enjoy your trip

I'd dive a single and sling an ally 12 for the deeper dives. I did Red Sea on a twinset and it was ok bit a bit of a PITA.

11kg is quite a lot for single tank RS diving .... IMO. I dive single 80s with a 5mm wetsuit and need 5 kgs....... a set of doubles needed about 6kg, I estimate (There was a fixed weight on the doubles so it's a bit of a guess).

Mal,
The old BCD i used was half wing / BCD i did try a full weight check after a dive on a house reef with 30bar and could not hold a 3mtr stop without poping to the surface,

the set up ill be taking on the Tala trip will be a 56lb wing & custom dives S/S back plate.
Ive done a pool check with my semi dry and 5kg was fine but it was with full tanks.

im not sure how patient the guy's will be doing a weight check as its a liveaboard. but may be once we have anchoured on a wreck i may be able to get a full check done.

Dont forget fat floats hence the special K diet ive been on now for 3 weeks

I don't know how MV Tala operates but usually the first dive of a liveaboard is on an "ok" reef with the specific purpose of making sure that any dive rust is cleared off and time is taken to get your weighting sorted .... do take that time if it is available, would be my advice because it will pay you back loads, later in the week.

Have a great time

The first dive, as Mal says, is on an easy reef of around 10-12m to make sure that you have all your sh1t squared away. They will also expect you to be able to launch an SMB mid-water.

Tala is a great boat and the boys on board won't have a problem with you jumping on and off the boat to adjust the weight as required.

Pass on my regards to Faisal when you are out there.

ive just turned to twinset diving and done my first dive in the ndac sunday.

with a 15ltr cylinder and a 2mm ri othree suit i use 10kg in fresh water and 12kg in the sea.....

....done a weight check sunday in NDAC fresh water (twin 12 steel/ri othree DS) only needed 2kg (which i was very happy with, less weight the better)
