Been diving about 9 months myself - started by doing my PADI Open Water in Cyprus then joined my local dive club in Scotland since and started diving lochs mostly, that necessitated dry suit spec then did my Advanced OW followed by Nitrox spec and Deep spec. Have been to 40m a few times, would like to go deeper but realise it's into tech diving and expensive gas mixes. Will do Wreck and Drift specs next as well as Rescue Diver cert and settle for 'Master Scuba Diver' cert from that lot for now - would like to head down the Divemaster route but don't have the time to devote to it.
Invested in all my own kit including a couple of 12L Cylinders but would like to add a pony bottle for the deeper stuff as you start to realise your mortality!
Have a Shark Dive coming up soon at Deep Sea World in Fife - should be interesting!
Cheers,
Brian.
