Argo Liveaboard
The Argo is incredibly well run by the Undersea Hunter Group. I have been to Cocos 3 times on the Argo. The dive operation, facilities and boat are very top quality!
Of course the diving at Cocos is spectacular if you like sharks. Large schools of hammerheads, hammerheads coming in close to cleaning stations, Galapagos sharks, tiger sharks, huge schools of jacks, snapper, and lovely swim-throughs are part of the diving. For a change of pace, too, there are a couple of shallower dives that include frogfish, stonefish, boxfish and other photogenic species besides sharks. Large eels, octopi and a wide array of life can be found here. The Galapagos, Cocos and Socorro are some of my favorite destinations.
The dive area and camera tables are laid out perfectly. It makes sense that one of the owners was a captain in the Israeli Navy. He has an engineer's mind and this operation is designed and run tightly as you would expect of an engineer or a navy captain.
The food is great and customized for those with food allergies. The cappuccino machine delivers tasty caffeine with or without steamed milk 24/7.
The guides are personable are knowledgeable. Very explicit on diving methodologies, profiles and dive briefings.
The Argo is the best liveaboard experience I have enjoyed. I am a past dive instructor with over 1600 dives around the world.
