Dove Key Largo this past weekend: Molasses Reef, French Reef, and Benwood Wreck.
Chartered through Scuba-Do.
Was very impressed with their dive operation. Granted, it may be the off-season, but for 3 trips (6 dives) there was never more than 5 divers on the boat plus Captain Mike and a dive guide/instructor (either Amber, Toni, or Diego). All were professional, approachable, and fun-oriented. I brought my own equipment and gear, but the staff seemed very patient with those novice divers that required rental equipment or some extra TLC entering and exiting the water.
I recommend Scuba-Do and would dive with them again.
As for tipping, my buddy and I tipped $50 each (roughly 20% of total cost) to the Captain at the end of the 3 trips. He said he would distribute fair shares to the respective dive guide/instructors.
Happy Diving,
AC
