Comments about Oceanic Din Conversion Kit for 1999 Year regulators & Later:

After two dives on the new regulator with the DIN adapter there was a small air leak coming from the body of the reg. I put the yoke back on and re-tested, thinking I was going to return the reg itself, but it didn't leak at all. So I put the DIN back on and sure enough, little air bubbles. There really isn't enough air escaping to make that big of a difference so I'll mess with it a little more but I'm not all that concerned.
I wouldn't reccomend this product only because I'd go with another brand of regulator all together.
