Question: 1 / 400

What do you want to avoid flushing your mask underwater?

To prevent getting disoriented

To ensure that the mask stays in place

To prevent water from entering, which can cause discomfort

Flushing your mask underwater is an action typically avoided to prevent water from entering the mask, which can indeed cause discomfort. When you flush a mask while diving, the incoming water disrupts your visibility and can create an unsettling feeling, especially if your mask becomes filled with water. This discomfort can divert your attention from the task at hand, forcing you to focus on clearing the mask rather than enjoying the dive or monitoring your surroundings.

Additionally, a mask filled with water can present a safety concern, as it obscures your vision underwater. Proper sealing and ensuring the mask fits correctly are essential to maintain comfort and clarity during your dive. Understanding this can help divers maintain a positive experience while underwater.
