My husband and I went to the Cocos Islands on the Okeanos Explorer. The amount of fish life, the hammerheads, breaching baby mantas (we didn't know they did that), a very close and wonderful encounter with a whale shark and even the red-lipped batfish were unforgettable. It was hard, current-filled diving from pangas. Water temp varied (upper 70's to the low 60's) and currents often ripped. We had reef hooks to help us hold on to the rocks that were often covered in barnacles. Everyone was required to wear a transponder (supplied by the boat). Are diving conditions in the Galapagos similar to Cocos? We are going on the Humboldt Explorer in the enar future and I wanted to level-set my diving expectations. My husband and I are veterans of 900+ dives in Australia, Pacific, Hawaii, Bahamas and Caribbean over the past 20+ years so we are not novices. Any and all comments and insights are appreciated.
