Working toward Cenotes
With GF 70, that is 2 minutes at 15', thus one of the simplest technical dives.hit 165ft for less than 5 minutes
GF 90 gives no deco.
Though if you believe in clearer heads, and I do, then some He would have been good and made it a less simple tech dive, and doing it deep air makes it less simple in other ways.
How "very slowly" for the deeper ascent?
GF80, 20'/min ascent rate to 100', then 10'/min to surface gives no deco.
