Air trapped in hood??

Most divers will at some point get a hood that is slightly too large and it will bubble up making you more positively buoyant with air trapped and looking like a cone head. Well with a simple search on the net it is easy to find how to sort this so I am not claiming anything on this one but felt it was worth mentioning.

The easiest way to solve this is to get a wire coat hanger, straighten it out and heat the end up till it is red hot, not hotter else you will set fire to the neoprene and have the hood outside if you can or at least open the windows for the fumes. I stood mine on an axle stand which seemed to work really well, but anything that lifts the hood and keeps it steady while you are concentrating on making the holes would work.

This is hot enough to melt but not set on fire.

What I found was that none of the things I read on it mentioned one important thing, which is really simple and basic physics. Turn your hood inside out, melt the hole from the inside and you will get a thin funnel to the hole and a smaller and neater hole on the external side. If you think about how you are positioned in the water then the front hole would be melted at a slight angle back from the front of the hood and the rear holes would be made by pushing the wire through toward the back of the hood, it doesn’t have to be massive channels but will help with the flow of air out of the hood. If you do not make the channels and go for a level hole through, still make it inside out as will get a neater hole on the external.

This is what not to do, melted from the outside.

As you can see neater holes, but this is on the inside on my hood.

You will need a pair of pliers to hold the wire as you heat it, and then move it to where you have your hood. I have not been diving yet to try this out but as soon as I do I will let you know the outcome of the wise information that many a diver that has gone before me. I made 4 holes in my hood, and 3 or 4 seems to be the amount that is advised on the many posts you will find about this, in a few weeks when the water temperature has increased I will know if it works or if I have ruined my hood, so if you try this I hold no responsibility for your kit but many have before and seem happy with it.
