I dived with Clive quite a few years ago, and if I were to go to Aruba again, he would be the first one I would check with. On the other hand, unless his operation has changed since then, he may not be the best choice for a brand new diver. He was the total operation--he took your reservation, picked you up at your hotel, fitted any gear you needed, helped you onto the boat, skippered the boat, got in the water with you for all of some dives and part of others, helped you back on the boat--everything. When I said "Part of others," I am talking about drift dives, where he would anchor the boat, join you for half of the dive, turn around, swim back to the boat against the current, start the boat, haul anchor, and come and pick you up when you surfaced.
If he is still dong that, I would suggest that new divers would want a larger operation.
