Greatever G2 Full Face Snorkel Mask with Dry Top, Panoramic View, and Camera Mount

The Greatever Snorkel Family - Ensuring a Seamless Snorkeling Experience

Before using this product for the first time, it is advisable to receive professional training and guidance. If such training is unavailable, thoroughly read the operating manual, check the mask's fit, and ensure it is comfortable and well-adjusted. Avoid overtightening, which can cause facial pressure, and ensure it is not too loose to prevent water leakage. Begin by practicing in shallow waters, and gradually increase the snorkeling duration as you become more accustomed to the activity. Beginners are recommended to take a 10-minute break after snorkeling, while experienced snorkelers should rest for 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 may cause some users to feel breathless or even dizzy. If you experience difficulty breathing or dizziness, immediately remove the mask by releasing the side buckles while wearing a life jacket and breathe. You can also go ashore to remove the mask and breathe.

It is recommended to always wear a life jacket while snorkeling and snorkel with at least one other person. The underwater environment can be complex, and individual physical conditions vary. Ensure safety and protection when entering the water.

When there is a significant temperature difference between the surface and the bottom of the water, snorkeling masks are prone to fogging due to the temperature difference causing condensation inside the lens. Here are some suggestions to address this issue:

1. Use an anti-fog agent: Before snorkeling, apply an anti-fog agent on the inside of the mask. This agent forms a protective film that reduces direct condensation of moisture on the lens.

2. Pre-soaking: Fully immerse the mask in water before putting it on. This equalizes the temperature of the mask with the water, reducing fogging caused by temperature differences. Wear the mask after its temperature has stabilized to effectively reduce fogging.

3. Continuous use: As the temperature stabilizes during underwater use, the fog usually gradually dissipates. Therefore, after spending some time underwater, the issue of fogging often naturally diminishes.

The Greatever Snorkel Family features a float ball system with the following working principles, design, and functions:

1. Working Principle: When the snorkel is fully above the water surface, the float ball sinks due to gravity, opening the snorkel and allowing air to enter, providing sufficient oxygen. When the snorkel is submerged, the float ball rises due to buoyancy, closing the snorkel opening to prevent water from entering. This design ensures breathing safety and comfort in different environments.

2. Waterproof Design: This product is only suitable for surface snorkeling. When diving underwater, the float ball system at the top of the snorkel automatically prevents water from entering. As soon as water contacts the snorkel, the float ball quickly rises, closing the snorkel opening to keep it dry and prevent choking. However, this will result in a lack of air in the snorkel, causing breathing difficulties. Therefore, users should return to the surface as soon as possible to avoid breathing difficulties.

3. Impact of Waves and Head Movements: On the sea surface, with waves or when the snorkeler is observing the seabed, if the head is tilted too far forward, the float ball will automatically adjust according to the water level. The design of the float ball allows it to rise and close the snorkel opening when it is below the water surface, preventing water from entering.

4. Blowing to Reset: If you dive underwater, remember to exhale (not inhale) while ascending to the surface to ensure the float ball descends again. Make sure the float ball moves freely within the snorkel and that the snorkel head is completely above the water surface before inhaling.
