    I'm looking to get a backup air source a 13-19 cu ft with a second on a 48" hose using it primarily in 40'-60' fsw. Does the DIN connection have any advantages over the yoke style? I use pro valves on my primary tank so swapping reg. out is not a issue I'm just looking for a buddy bottle on shallower divers.

    DIN has almost no disadvantages compared to a yoke valve. Although I'm assuming you've really thought out the "why I want a pony bottle" issue.

    DIN valve allows for a more streamline reg set up; no knob etc like on a yoke. Less chance of it getting snagged on something. Plus a little lighter.

    I'll second RJP, when I setup my pony, I figured that, other advantages aside, the more streamlined DIN connection would be much better. I didn't like the extruding components of the yoke for something that was hanging below.

    thanks the more streamline DIN looks to be the way to go I was questioning the yoke for the same reasons.

    DIN is def the way to go, I have changed the valves of two of my tanks and the pony. I know you did not bring this up - but consider getting a bigger stage. because you seem to be heading towards rec tec - an S40 would be ideal and you would be able to use it for longer dives and deeper dives with multiple O2 combinations.

    Just my 2 cents

    It is possible to knock a yoke reg off the valve, this can't happen with a din fitting.
