Thanks again, there is so many types, makes and different flavours of kit out there its good to get advice from people like yourselvez who have the experience.
Was looking at dive computers but again so many types and makes, some that do only air, others that only nitrox, but was looking at ones that do both, that would then do if carry on to enriched air, deep water courses, what are the recommended computers to look at.
And what are good makes of kit out there as thought Mares were a good make but looking at some regulator kits on places such as ebay and nobody seems to be buying them, with Scubapro and Apeks seeming to be the popular ones people are buying.
As already mentioned am new to this so any advice is greatly appreciated.
