I was looking at getting some ND dry gloves to go on to my compressed neoprene suit.

After chatting with one of the helpful chaps down there he mentioned I could use a short length of surgical tubing to equalize the pressure between the glove and the suit.

Has anyone done this and how do you find it?

I was not sure how it would work since surely the neoprene wrist seal would simply close the tubing off to stop any air the way it is designed to normally.

A 4" piece of bungie does the same job.

Or a pair of undergloves donned before you put your arms into the suit. This creates a small route for the air in glove to equalize with that in the suite. Just make sure the glove seals are over the suit cuff seals.:)

Gloves inside work depending on length of seal. A leak though will flood quickly.

A bit of bungee works best for me and is easy to remove quickly if needed.

Gloves through the suit seal does work for equalisation. I used to do this, but punctured a glove once. I removed the dry glove and attempted to remove the liner glove, but it woudln't shift from under the seal.

Result - flooded suit, and a very cold hand ;)

Bungee is the way forward. Or ZipSeals.

One Dragon: OK, I'll have two pieces of surgical tubing 4 inches in length please.

Shop Assistant: Certainly sir, that will be 14.99 please :cool:

Where do you shop? I want to avoid it

(not sure which type of tubing you mean as either would work for dry gloves)

Used to use this but not since one dive where the tubing slipped back under the seal when on the bottom phase of the dive.

The result was an "interesting" ascent, with a balloon rather than a hand :eek: - it almost got to the point where poping it was considered but I found a pin-prick hole in the thumb and spent the time at each deco stop squeezing out the gas before having to ascend up to the next stop.

Now I use "glove through the seal" method, works much better IMHO.

To be fair to him, he didn't offer to sell me any. He did a google search whilst I was on the phone and told me there were lots of sites selling it for somewhere about a fiver or less.

Think I will try the gloves.

Do people buy specific under-gloves? Or just get a pair of woolly ones for £2.99 at the local corner shop?

I use 40gsm thinsulate gloves from my local outdoor shop.

I use the one size fits all strech gloves, (from the pound shop) as my dry gloves are lined already. Works fine for me in 4deg C water for 40+ mins before a feel the cold.

Me too.

Incidentally, I am a surgeon, and we don't use "surgical tubing" any more - its all plastci stuff now - hence the prices quoted.

Hi Ron,
Have you "operated" on your club compressor lately. :D
