Hi,


I am fairly new to SCUBA diving and only have 13 dives under my belt. At the weekend I went diving for the first time this year mainly to try out the new equipment I have bought. Everything was fine during the decent (we only went to 12 meters max) but on the ascent the automatic shoulder dump on my Northern Diver Cortex dry suit seemed to stop dumping air at about 6 meters, which meant I could no longer control my rate of ascent. This was not fun and was pretty scary. No matter what I did I could not seem to make the valve dump sufficient air to keep me neutrally buoyant. I had to keep fining downwards to regain control. I believe the problem to be related to the under suit I was wearing (a weezle extreme plus) which I think was blocking the dump valve when the air was expanding inside the dry suit.

Has anyone else experienced similar problems with under suits hindering the dump valve?

what to wear under your suit

Hi, I too am having the same issue with my undersuit, which happens to be the same make as yours.

The valve on my shoulder appears to be blocked by the suit, thus causing the same issues you described, only I was having real issues at 9.5 meters staying down.

I have heard that a bandage or similar around the arm where the valve is helps, though as yet I have not tried this.

The problem with diving in the UK is that warmth is a major factor, hence the purchase of the undersuit.

I too would be interested in hearing from anyone who has experience this problem or who has any hints or tips regarding the undersuit.

G :D

You might like to try sticking some duct tape (the strong silver stuff) on the arm of your undersuit, under the valve. Some of the wooly bear type suits are very prone to this because of the fabric, although the thinsulate ones are less affected because they have a smooth outside.

Hope this helps
