@Shearwater, in another thread,
Can anyone suggest a computer for returning to altitude after a dive
the question of driving home to altitude was raised. While I don't expect you to offer up an answer as to what's "safe", I'm hoping you can comment on the theory.
In surface mode, can I track GF99 over time? In other words, as my tissue map blooms in the last twenty feet of my dive, and I presumably surface with my planned SurGF or GFHi, my GF99 will begin to fall during my surface interval.
Will my Perdix then track altitude as I drive home? And will my GF99 show an increase if I jump in the car and start driving up the mountain? And can I display it in real time after my dive?
And finally, is my logic correct in thinking that if I keep my GF99 below whatever arbitrary value I've decided is safe, that using that to track risk of ascent after diving is valid? Note that I'm NOT suggesting using this to fly after diving, due to the sudden increase in cabin altitude, not to mention the risk of cabin decompression. Rather, I'm contemplating using this to help me get over the pass from my Lake Tahoe dive, and decide how long before I get in the car.
