Achieving a proper seal when clearing a mask is crucial because it prevents water from leaking in during the process. When a diver needs to clear their mask, they may experience some water entering due to changes in pressure or movement. A good seal ensures that the water does not re-enter the mask after the initial clearance, allowing the diver to maintain clear vision and focus on their surroundings underwater.

Maintaining a proper seal is essential for ensuring that the clearing process is effective, allowing the diver to easily expel water without the risk of it flowing back in. A well-fitted mask enhances comfort and safety, contributing to an overall better diving experience.
