What wreck were you guys on?I was among the 5 divers in the article. Each of the 2 dive teams had a surface marker buoy and flash lights. The dive was called as soon as it was realised that the mooring line had pulled free of the wreck. SMB's were deployed on reaching the surface and the 2 teams gathered and waited together on the surface to wait for recovery. I flash light was lit to signal the boat as the weather was heavily overcast. We are a group of well trained and experienced divers which contributed to some complacency (not everyone had their own SMB and/or light).
Lessons learned: every diver needs an SMB and light whether you think you do or not. Redundancy is never wasted. I will be purchasing a GPS Personal Locator Beacon before Ocean Diving.
