I used to dive solo a lot near a pier at place called Portencross and fly a blue diver down flag from the shore until I lost 3 of them. 2 were stolen, maybe Rangers F.C. supporters, the other was thrown in the sea, most probably Celtic. I tried a float after a near close encounter with an inshore trawler. I discarded the idea after being fly hooked by bored anglers using it as a target. What I really want is a buddy on shore with a deer rifle.
