Kevin,
The new handsets look REALLY nice.
It is so funny, I just got off the phone with someone and we talked about how cool would it be to have an user-adjustable battery warning feature. Then I hung up the phone and read your post...
Whoops, there it is...
Would it be possible to install the new secondary to, say... the Vision lid for back up PO2 secondary and have a redundant trimix computer ?
