Hey Mark, I just bought a used drysuit, it's in really good condition with all new Neck and Cuffseals. Unfortunately, my neck is VERY slim and I'm pretty skinny to begin with. Sometimes when I move or stay upright in the water, and all the air moves upwards, the seal breaks and I get a bit of water inside the suit, nothing major but still annoying. How would I best fix that? I thought about getting a custom latex collar which fits my neck perfectly (which I put on before I put the drysuit on) and then put the drysuit neckseal over that. Maybe another collar over that to sandwich it in.
Thank you for your advice.

Hey Mark, I am relatively new to UK diving and deeply dislike the cold. What is your ideal baselayer & undersuit combo for drysuit diving in the UK in Summer and what changes for Winter? Also, what are your thoughts on heating systems such as the Santi BZ400 extreme/ heated vest? - Thanks

is advanced open water a pre-requisite for progression to other courses? Or can I just cherry pick specialities after completing open water

Hi Mark, You are my second favourite show! (the first is "better call Saul")
Thank you very much for all the informative videos. Now, unfortunately, I have noticed that there is a small scratch on my Perdix Ai. Is it possible to remove it? Or changing the front element?
Thanks
Ido

I'm a new diver and I'm using my air pretty fast. If I get a 130 cu/ft tank, do I need to change my 1st and 2nd stage? I have a cressi AC2 for primary and the octo that comes on the set.
