How to Prevent Dizziness & Adapt to Your Snorkel MaskPre-Use Preparation

1. For first-time users, seek professional training from a certified instructor. If professional guidance is unavailable: Carefully read the instruction manual. Test the mask fit: Ensure a snug, comfortable seal without over-tightening (to prevent facial pressure) or looseness (to avoid leaks). Practice in shallow water first. Gradually increase snorkeling duration as you adapt. Rest intervals: Beginners every 10 minutes; experienced users every 20 minutes to restore energy and lung capacity.
2. Managing Discomfort or Dizziness WARNING: Lack of training or unfamiliarity with aquatic environments may trigger panic, rapid breathing, and rapid air depletion in the mask. Insufficient airflow can cause breathlessness or dizziness. If symptoms occur: Immediately loosen the side buckles while wearing a life jacket and remove the mask to breathe. Exit the water promptly if needed to recover.
3. Safety Guidelines Always wear a life jacket and snorkel with a partner. Water conditions and personal fitness levels vary—prioritize safety.

Preventing Lens Fogging Temperature differences between water layers may cause fogging. To minimize this:

• Apply anti-fog spray to the inner lens before use.
• Rinse the mask with a mild soap solution and air-dry (avoid wiping).

Float Valve System: Design, Functionality & Safety

1. How It Works

• Mechanism: When the snorkel tube is fully above water, the float valve drops by gravity, opening the air channel for continuous oxygen flow.
• Water Protection: If submerged, the float valve rises via buoyancy, sealing the tube instantly to block water ingress. This ensures safe, dry breathing in dynamic conditions.

2. Waterproof Design

• Surface Snorkeling Only: Designed for use at water level. During underwater diving, the float valve activates to prevent flooding.
• Critical Note: If water triggers the valve, airflow stops. Return to the surface immediately to avoid oxygen deprivation.

3. Wave & Head Movement Adaptation

• Automatic Adjustment: Waves or forward head tilts may submerge the snorkel tip. The float valve responds to water levels, sealing the tube to maintain dryness.

4. Reset Procedure

• After Diving: Exhale gently when resurfacing (do NOT inhale) to reset the float valve. Confirm the valve moves freely and the snorkel tip is fully above water before breathing.
