Every dive gets a briefing with the site drawn on a board, the current named, the plan for the pickup and a maximum depth that is ours rather than yours.
On the southern itinerary the briefings are longer and the buddy checks are done in front of a guide. Guests occasionally find that irritating on day one. Nobody finds it irritating by day four.
There is one recompression chamber in the country and on the southern trip we can be nine hours from it. That single fact decides every profile we run.
