Adjusting your scuba equipment before entering the water is essential for safety, comfort, and effective diving. By making these adjustments prior to the dive, you ensure that your gear is properly fitted, which can prevent issues such as equipment malfunction or difficulty in maneuvering underwater. A well-fitted wetsuit, buoyancy control device (BCD), and other gear contribute to optimal comfort, thus allowing you to focus on the dive itself.

Making adjustments while floating on the surface can be tedious and may disrupt your buoyancy control, affecting your overall safety. Adjusting gear once you're already submerged can lead to panic if something feels off, and waiting until you're under 10 feet before making these changes increases the risk of complications. Moreover, only addressing discomfort during the dive means you could be diving with improperly fitted gear for a significant portion of the dive, which can be hazardous. Proper preparation and adjustment before entering the water is the best practice for a safe and enjoyable scuba experience.
