It looks like someone is selling a dive boat in Key Largo. I'm not familiar with the dive ops down there.

C.L.U.E.L.E.S.S.We were staying nearby, doing 2-4 dives a day, I was considering a trip with them, they had no option on their booking system, so I asked if Nitrox was available, here's their answer:
As far as nitrox goes for the normal diving depths in Key Largo it provides no benefit

For shallow reefs dives of 30 feet or less, the benefit of nitrox is minimal. If that’s their bread and butter I could see why they wouldn’t invest in a nitrox system (or in buying nitrox from other operators), especially if they are a small operation. If they ever hit the Key Largo wrecks or anything over 40 feet the benefits of nitrox become more significant.
I am well aware of nitrox and shallow dive thing. My point was (and reasoning for Nitrox) less N2 sat during multiple repetitive dives, shorter SI's, more conservative safety profile (we are in our late 50-ies). We did 4 dives the day before, 5 the day before that, and were planning to do two more the afternoon after BWD. And yes, many northern Key Largo dive sites hit 40 or 60'.
All they had to say - no, we do not have Nitrox, sorry.
