A useful safety device for most divers is the surface marker buoy. In essence it is an easily seen surface float which is connected to the diver by means of a thin, strong line, usually carried on a reel.
From looking at sites offering some points of history in regard to diving in Australia, I found nothing in relation to what was once the highest volume retailer of SCUBA equipment and dive accessories in the Southern Hemisphere, circa 1960's.
I have now been scuba diving for over 25 years and have a pretty good training record: - 1980 Open water Diver - 1990 Advanced Open Water Diver - 2004 Rescue Diver by this plan I should be an Instructor just under my 90th birthday.
