| I shall take a stab at some Rebreather reccomondations then.
As you want to do techie stuff that rules out the Sport Kiss IMHO.
That leaves you with most of the others - how do you feel about Electronics? Also any thoughts about whether over the shoulder lungs would be ok or would make you feel cluttered?
Best bet is to try and get some try dives on a few rebreathers and see what you like - I would suggest trying out a Classic Kiss, Evolution, Meg and a Prism.
They are all fairly good to travel with and well thought of.

PS I like Darlenes reccomendation on doing Normoxic on OC first but just as a FYI - Sarah went straight from OC Adv Nitrox / Deco to CCR Trimix. It can be done but its harder. |
