Our dives are 60+ minutes 95% of the time (even those who start the week getting 45 minutes) - and very often go 70/80+ minutes depending on the divers - and no, that's not just Columbia shallows -
So guess how long those same dives would be on steel 120s... I'd venture longer, but now I'm learning the reality is they would be shorter.
As I said, only on scubaboard...
Nobody needs to justify why they don't provide steel 120s, it's your business to run as you see fit.
But for people to be 'annoyed' by others 'repeatedly' 'bringing it up' (steel 120s) is ridiculous. I could be annoyed at people repeatedly bringing up the advantages diving with a valet op or an op that uses small fast boats. To each their own.
Now, Christi if you bend reality by getting longer dives on tanks with less air, so be it.
But the whole discussion of an argument on the basis of more air on a dive is bad is to me is either ridiculous or is a dive operator making a futile attempt to diminish an obvious perk of the competition.
Only on scubaboard is more air bad when it comes to scuba diving. Silly, silly, silly.
Why even dive al 80s, wouldn't 40s be all anyone needs?
