Ha, I used a MKII second stage, just like yours, as my octopus connected to a MK6 first stage. The Mk6 was a variation of the MK5 differing only in the manner in which the first stage attached to the tank valve. Th Mk5 screwed on, like most regulators, and the MK6 attached via a spring loaded yoke.Gatt wrote:

Anytime I put my diving gear on there is someone who wants to buy it
