Hello everyone, thanks for allowing me to join this fine group. I live in Brisbane Australia, and am Tech certified with PADI to Tec45. It was time to make the decission of continuing with open circuit or transfer over to CCR. Well CCR won for a number of reasons outside of the obvious cost savings of Trimix diving on CCR. So I am currently searching for my first second hand Rebreather and I pretty much have my heart set on a Poseidon SE7EN, although I would certainly consider a Mk VI also. So If you can help with my Search that would be awesome. Looking forward to joining the bubbleLess Revolution!!! Cheers Seano
