Just a follow up to this, for anyone interested. I dove Saturday morning and afternoon with South Florida Diving HQ. I went out with Dave and Nicole in the AM - they were great. The dives were simply ok, compared to the places in the Caribbean I usually take trips to. However, it was nice to just get my fins wet. I also signed up for the afternoon dive - which I later found out was two dives instead of one. Thus, on my 4th dive I kept bouncing off of my deco limits, as i chose Air instead of Nitrox all day. My Air integrated computer said i was barely out of deco limits, while my stand alone Mares computer started freaking out telling my I was in deco. I chose to be conservative and follow the Mares computer on its profile.
But anyway, I enjoyed the diving. There's a great diving scene in that part of Florida and great commoradery. The water temperature was an awesome 84 degrees. I would definitely do it again if I manage to go back to FLL for business.
