What is the primary reason smaller dive teams are preferred in smaller caves?

Smaller dive teams are preferred in smaller caves primarily because they create fewer bubbles and less turbulence. This aspect is vital in underwater environments, particularly in tighter spaces such as caves, where a reduction in bubbles can lessen disturbances in visibility and the aquatic environment. Turbulence can displace sediments, which would further reduce visibility and potentially disorient divers. Maintaining a clear line of sight is crucial for safety and navigation, and smaller teams facilitate this by minimizing their overall impact on the water and surroundings.

While the other options may seem relevant in their own contexts, they do not directly address the unique challenges posed by smaller caves. For instance, easier navigation may be a benefit of smaller teams but is not the main reason for their preference in tighter spaces. Team experience can certainly play a role in a dive's success, but the emphasis here is on the immediate environmental impact. Similarly, while it's true that smaller teams might have less logistical demand during preparation, this is not the central factor that drives the choice in the context of cave diving conditions. Overall, the need to maintain a stable and clear environment makes the creation of fewer bubbles and less turbulence the primary reason why smaller dive teams are favored in these conditions.
