The Historical Diving Society of Sweden, Svenska Dykerihistoriska Förening (SDF), is worlds oldest such society. It was founded in 1979. It managed to get hold of a building called the Dive Tank House, “Dyktankhus”, that was used as a training and research station in the Kalärvarvet submarine fleet base. In the building there was a dive tank for submarine escape training. There was also a hyperbaric chamber for research purposes and a steam generator. Hot steam was used to maintain the operation readiness of submarines. Today the building houses a museum of diving history maintained by SDF.
A number of photographs from Dyktankhuset can be viewed below. The place is worth a visit but you are encouraged to check the opening times in advance. This museum is in the immediate vicinity of the Wasa museum.
Diving is a splendid hobby. It caters wonderfull views under the ice on a sunny winter's day and on other days one can venture into exciting submerged mines. Search and recovery diving and historical diving both add to the diversity of the hobby. And abroad there are warm waters and major adventures, although these seldom coincide. Add some publishing and web maintenance and you'll end up with a varied hobby that I can only recommended! I am most proficient in search and recovery diving and in sump diving (a form of cave diving).
At the moment I am maintaining two websites besides this one and am editor-in-chief of Luola, the journal of Finnish caving society. Other associations that I hold dear include my dive base Sukellusjaosto of Turku YMCA and the information security society TurkuSec.
