Please, please please. I am not anti dry suit, I may end up getting one myself. Nor do I wish to write a very long post with coverage of every detail of what I know or how I came across information.. In making my original post I had looked at the first posts made by the thread originator. I only intended to suggest he step back and give a bit more though before making an expensive purchase. I do not wish to denigrate Adsdiving883 (Adam) in anyway but he is still only in the middle of OW training. Bearing in mind the relatively low cost of hiring gear at Capernwray perhaps hiring is a better option than purchase for a dry suit for the time being. You can get a wet suit for roundabout £100 or less that will do a fair bit of the time. Drysuits start at a lot more than that and if you want made to measure about £900. Adam had commented that he felt wet suits looked expensive. I do fully understand how wet and dry suits work, neoprene compression, insulation etc, and I did qualify my use of the word negative by putting the word "just" shortly before it. I still think its fair to say that for most if not all divers the priamary reason for wearing a dry suit is warmth. I mentioned my brother. He has done maritime reconnaissance and air sea rescue round the UK, Iceland, Canada, California, South America / Falklands, Australia, Midway and the Eastern Mediterranean for extended periods and briefly in a few other locations. He has also chaired accident investigation committees. Although he retired a few years ago there was already concern that the increasing use of dry suits was leading recreational divers to over extend themselves, because it was enabling some to dive in conditions and or locations where they should not have been diving, for physiological and experience reasons. That possibly tallies with post #40 comments about the HSE tightening up. There is always 2 ways (at least) to look at things. Take dive computers. When I was buying my BCD and regs the dive shop felt I should also be buying a computer. The seller was an experienced and keen diver, and I think he genuinely felt it would be in my best interests to have one, not just trying to make a sale. On the other hand my instructor (who has probably done 15,000 + dives) said don't bother with a computer for some time yet, learn to use tables and get a good feel for diving first. I just looked up Portimao where my son learned to dive in March a few years ago. The sea temperature in March is only 16 (cooler at diving depths) and only gets up to 22 at hotter times of the year. Despite these temperatures and the fact they have dry suits with argon filling available for extra warmth the training and many dives are done in wet suits. North America too seems keener than the UK in continuing to dive in thick wet suits / farmer johns than the UK.
