Visibility is typically between 100 and 150 feet and sea conditions are usually calm. Most dive sites are in the lee and rough seas are rare. The dive sites are almost all walls so the possibility of going deep is always available. You need not dive deeper than 40 feet if you are keeping a shallow profile. Generally the first dive of the day has interesting things to see as deep as the 130 foot sport diving limit.
Second dives are more toward the top of the wall.
On afternoon dives we try not to exceed the maximum depth of the first dive to keep a conservative profile. Dive computers are not required but are highly recommended. We do require computer divers to have one per person as is a standard safety practice. One of our divemaster staff , all of whom are instructors, is in the water on every dive. You can take a guided tour of the hot spots of the dive site or explore the wall with your buddy.
