Product description 3 Key Tips to Prevent Snorkeling Mask Leaks 1.Ensure Proper Fit Press the mask lightly against your face and inhale through your nose to test the seal (it should stay suctioned if fitted correctly). Adjust strap tightness – not too loose or tight – and remove any facial hair that may break the seal. 2.Relax Your Face & Breathe Through Your Mouth Avoid smiling or frowning to prevent facial movements from breaking the seal. Breathe only through your mouth to minimize air pressure changes inside the mask. 3.Clear Water & Maintain Your Mask If water enters, tilt your head back slightly and exhale to purge water through the valve. Rinse the silicone skirt with fresh water after use and store it in shade to prevent damage. Master these 3 steps for a leak-free snorkeling experience! How to Deal with Dizziness While Snorkeling and Adapt to the Snorkeling Mask 1. Before using this product for the first time, it is best to receive training and guidance from a professional coach. If professional training is not available, please carefully read the operating manual, check the fit of the mask, and ensure it is comfortable and well-fitted. Avoid over tightening to prevent facial pressure, and ensure it is not too loose to avoid water leakage into the mask. Practice snorkeling in a shallow area initially. As you become more accustomed, you can gradually increase your snorkeling time. Beginners are advised to take a break after 10 minutes of snorkeling, while experienced snorkelers should rest after 20 minutes to replenish energy and lung capacity. Without professional training, unfamiliarity with the water environment can lead to nervousness and rapid breathing, quickly depleting the mask's air supply. Insufficient air intake can cause some users to feel dizzy. If
