MK25-Which end is up?

[Peter_C]

The new MK25s have an "AF" suffix which means "anti-freeze" which adds fins to the lower part of the regulator, among other things. So you probably have a MK25 without the "anti-freeze" goodies. To see if it truly has the MK25 features, which would be an adjustable IP, you should look in the top of the regulator where the plastic cap is, and see if there is a hex key adjustment in the center.

From what I have read, you can add the anti-freeze package on. Not sure if Scubapro will cover it or not, but they may very well do so as an upgrade. If you dive water colder than 55 degrees or so it would be a good addition and could be done when the regs are serviced.

FWIW I have mine plastic cap up to leave more room for my head, and less chance of it snagging kelp here in CA.
