How to use a diving mask

1. Putting on the mask - Place the mask on your face, making sure it fits snugly. Pull the headband over the back of your head.

2. Adjusting the headband - Pull the ends of the headband to adjust the mask snugly to your face. If the headband is too tight, loosen it using the buckles and readjust to a comfortable tension.

3. Removing the mask - Loosen the band using the buckles, then gently remove the mask from your face.

4. Entering the water - Keep the mask close to your face, holding it with one hand, especially when jumping into the water from a boat. Avoid diving headfirst or face down as a first step.

5. Adjusting the pressure - If you feel the mask being pressed against your face by the water pressure, gently blow air through your nose to equalize the pressure.

6. Fogging of lenses - If the inside of the lenses becomes fogged up, use an anti-fogging solution and then rinse the mask thoroughly with water.

Following these steps will ensure comfort and safety when using a snorkeling mask.
