Im gonna try it for sure. Im just thinking I'd never want to go beyond about 10m because if the worst happened I reckon you could get back to the surface from 10m on a single breath after dumping your gear. I doubt that could be done from 30m.
Im not that excited about diving in the UK seas to be honest. Feels like it would be cold (I know thermal gear is worn but still) and muddy. Hopefully if I can find a club they will run trips abroad?
Dumping gear and ascending rapidly to the surface is the last resort as it will lead to decompression sickness, even at 10ms depending on how long you’ve been down. At 30m you really wouldn’t want to be rapidly ascending, it would be like opening a bottle of pop that has been shaken, except the bottle is your body and the gas is in your bloodstream.
ideally your buddy will give you their octopus if both of yours fail or you will have a mini back up tank called a pony, club training will teach you how to stay calm and recover safely if you’re in trouble
Personally I feel after diving in the uk in a drysuit I would be confident diving just about anywhere , there’s plenty of nice diving sites in the uk that are not murky , they may be colder than exotic locations but in a drysuit and thermals it’s pretty comfortable unless the water temp is extremely cold, I’ve done 4 deg c a few times and that is pretty bad but I still managed 45 mins per dive , but you can always opt only to dive when the waters are warmer.
The farm islands when the seal pups are around is amazing, it is one of my favourite dives, also some of the areas around Eyemouth and st Abbs are amazing underwater ,just as pretty if not more so than some exotic locations
Most clubs will probably do trips abroad once you’re qualified
