I am interested in buying a new Micra reg. Is the 1st stage only offered as yoke fitting? I haven't seen anything so indicating there is a din version. If there isn't a din available, would there be any issues if I were to put the Micra 2nd stage on a Legend 1st stage? Thanks!

The Micra will not work with Legend first stage. The Legend regulator has a variable intermediate pressure and will need a pneumatically balanced second stage to work with it. The Micra does come available on several first stages and the DIN fitting should be available from any authorized Aqua Lung dealer and be attached to your first stage. You will need to use the Aqua Lung website to find your nearest dealer.

And also, if you are looking for a small compact 2nd stage and a better performing first stage than the Titan, look at the Mares Proton MR42 Metal regulator. It is tiny has a light weight 2nd stage and a very nice breathing piece of gear.

And you can find more info on that reg by clicking on http://www.scuba.com/scuba-gear-36/033113/Mares-Proton-MR42-Metal-Regulator.html
