Well, I love to dive both vintage and modern gear. It merely depends on the dive and sometimes the buddies I will be diving with. Thanks for the links Trapezus. And your enthusiasm.
DDiverdon , I thank you..in Europe especially in France very vintage diving enthusiasts do this hobby doing passionality. For example last week French vintage group dived in ice with wet suit..
I started in Turkey this passion.Now we are group who we dive with the vintage equipments and I have a good collection.
I say to my friends ,if you have a 1 vintage regulator single or doublehose, 1 back pack,1 mask ..you are a vintage diver.Biggest problem is short yoke regulators to connect the modern valve tanks. So we must prefer DIN yoke doublehose/singlehose regulators.
I have many vintage single hose and if I use a singlehose in my vintage diving I prefer Nemrod Snark 2 or Scubapro MK V.
