Plenty of dive spot in Loch Lomond, leave it till summer though! Was only about 20-30min dive as time was against me and only a 3L cylinder. Camera was a housed SLR in an Aquatica Housing. Good luck with your training!
oh yes haha, there is no one within 15 miles or something like that, Scotland is very remote- particularly the highlands, in the cairngorms where this is it is just hill after hill
