I know this is going to be a dah moment. I keep seeing people referring to "DIN" when discussing regulators. Such as "Wish it had the dry technology for DIN". What does the acronym DIN mean?
 
A DIN connector is a connector that was originally standardized by the Deutsches Institut für Normung (DIN), the German national standards organization. There are DIN standards for a large number of different connectors, therefore the term "DIN connector" alone does not unambiguously identify any particular type of connector unless the document number of the relevant DIN standard is added (e.g., "DIN 41524 connector").

GOOGLE is your friend.
 
When used in reference to diving, DIN usually refers to the method of attaching the regulator first stage to the cylinder. For a full explanation with pictures click here
 
Do you have a gas grill? The DIN regulator first stage attaches to the tank in a similar manner. Once the tank pressure gets above 3,000psi DIN fittings maintain the seal better. Everything is bigger and more robust.
 
DIN= Deutsche Industrie Norm as established by the Deutsches Institut fuer Normung.

in English, the German Institute for Standardization
 
Great link Druid. This has to be put somewhere prominently somewhere to ease the constant flow of misinformation would be a good idea.
Prodigious
 
The Deutsches Institut für Normung (DIN) has issued other diving-related Standards, one of them DIN 7876 of October 1980: Tauch-Zubehör; Schwimmflossen; Maße, Anforderungen und Prüfung (Official English translation: Diving accessories for skin divers; Flippers; dimensions, requirements and testing). This is a useful Standard for those who decry the lack of uniformity in sizing fins, both full-foot and open-heel. The Standard contains a table stipulating which foot width applies to which foot length when designing the dimensions of foot pockets. For example, the Standard specifies that the foot pocket for a foot length of 275 mm, which is in the shoe size range 11-13, should accommodate a foot width of 110-115 mm. I have an old pair of Dolfino Marino fins embossed on the sole with the data

DIN 7876-A. FL. 275. FB. 105.

This tells me that the the German Standard 7876 applies to the fins, they are full-foot fins (A=full-foot, B=open-heel), the foot pocket's foot length is 275mm and foot width 105mm. A foot width of 105 is smaller than the recommended range (110-115), so the pocket will be narrow-fitting, a feature of many Italian fins of the time. It's a pity that more fin manufacturers don't follow this Standard, which would help people work out which size of fins would be the best fit for their feet.

Thanks Druid. Pictures are worth a thousand words. Once I looked at the pictures I knew exactly what it was.
