I bought a scubapro Mk25 G250. But still planning to put an Octo to it. I have been using a Calypso6 second stage as my octo for my SE2. Can I also use this to my MK25 g250. So I won't have to spend money for another octo and buy a new set of fins instead.Is it possible? I'm just planning to make my SE2 as my spare reg during long dive trips. :dazzler1:
