I'm in the process of completing my ANDI Nitrox cert and have some questions I hope can be answered.
  1. Is it advisable to get a personal O2 analyzer to verify fills?
  2. I have a Poseidon Cyklon reg and ODIN octo with Poseidon analog console and both Cressi Arcimede Nitrox ready dive computer and my Suunto D3 which also does Nitrox as a backup - How would I find out if my regs are Nitrox ready? My local LDS isn't a Poseidon dealer.
  3. I'm looking to get my first personal tank - I want to find the balance between lightweight and max dive time. Being a freediver, I love the idea of a low profile (double 40's seem ideal to me) - any recommendations?
