We dived with Volker Pohl in Cozumel, before he changed to Aquamarinas. The dives we did with Volker were always great. He fully responds to the wishes of his divers in terms of dive site, depth and speed of the dive (of course, everything within reasonable limits). As a certified biologist, Volker is the contact person for everything that has been seen from the animal kingdom underwater; he knows all about it and not only that, he always writes a logbook with all the fish that have been seen underwater on several dives. Volker dives only in small groups (max. 6 persons). If there are two dives in between, it will take about an hour to break the surface and there will usually be biscuits, fruit and drinks. Volker builds the dive-trip on request and makes a very good briefing before and after the dive. In regard to hotel and flight search he is also helpful, if desired. We can only recommend Volker and look forward to the next dives with him.
