Looking over your report, and judging mainly against Caribbean diving, I see a glaring difference. Live-aboard diving Belize, the Caymans and Turks & Caicos (one trip each)...diving 90+ feet, and especially 100+, as a max. depth was unusual. The one dive > 100 feet on my Galapagos trip was where I got task loaded and let my buoyancy control lapse. The one trip where I had a number of deliberate dives with max. depths 100+ feet was North Carolina, because the offshore deep wrecks were...well, deep.
But you are in the Maldives, known for beautiful coral reef (and associated tropical fish) diving, I believe...and you're hitting the 90 - 100+ foot max. depth level quite often. So, my questions...
1.) Does the boat have an option for tanks larger than the typical 80-cf tank? If so, what are most divers using?
2.) It's one thing to briefly dip down to see something special, another to spend substantial time at depth (e.g.: 'square profile' diving - like on the offshore wrecks out of North Carolina). Are you guys spending much time at those depths? What depths do you tend to use the reef hooks?
3.) Does having a good SAC rate/gas consumption rate seem especially important for Maldives diving? Is that something that people who aren't good at it might consider grounds to pick another destination?
4.) Is everyone diving nitrox?
5.) Why are they diving that deep (compared to, say, the Cayman Islands, where one could easily do so but doesn't)? Are you looking for something specific to those depth?
6.) How does the diving depth of a Maldives trip compare to Raja Ampat, Komodo or Palau? Any idea?
A number of Scuba Boarders seems to have gills, but not all of us are like that. The best way to bring a smile to my face at a dive shop is to say 'Why yes, we rent 120-cf steel tanks!'
