I think I would probably prefer a wrist mounted computer and understand that I'd need to have a SPG also then. I would probalby like air intergrated to but getting a transmitter from what I am seeing throws the price way above my budget. I haven't really seen an AI in my price range.
What about the compass? If the wrist mounted computer doesn't have a compass (which it appears only the more expensive ones do) what do people do about the compass?
an air-integrated computer that is contantly keeping track of my current gas remaining, my consumption rate, nitrogen loading and PPO2/ox-tox risk.
For $600, AI writst mounted is definitely possible.

They are new. If you don't mind used, they can be had for much less. But again, I don't think AI offer too much value other than convinience, something I will skip if budget is tight.
As for compass, mount it on left wrist. So computer on right wrist.
