In wreck diving, what is an important agreement that dive buddies must come to?

In the context of wreck diving, it is vital for dive buddies to agree on a primary goal for the dive. This agreement ensures that both divers have a clear understanding of what they want to accomplish during the dive, whether it's exploring the wreck, photographing it, or conducting research. Establishing a primary goal helps maintain focus and enhances safety by ensuring that both divers are aligned in their intentions and can support each other effectively throughout the dive.

While dive conditions and weather, emergency procedures, and equipment checks are all critical aspects of planning a dive, they serve more as preparatory steps rather than defining the primary objective of the dive itself. The primary goal drives the dive plan and influences decisions regarding depth, time underwater, and the approach to the wreck, making it a crucial agreement between dive buddies.
