I agree fully with MaresMan1
For me they are both a new, safe and very good BC'S.
I could be the Airtrim instead FCS system without a problem...i have choice the Cressi BC'S becuase i like your design and other small things...
Yes, i know, i said with i have choice Cressi because use a mechanical system instead a pneumatic system...but i think also which a Mares and Cressi have a good Engineers both
So, if you can, try both...
Bye bye to all friends diver!!!!
