A snorkel is an essential tool for exploring the wonders of shallow seas. It allows you to breathe freely without frequently lifting your head, immersing you in the amazing scenery of fish and coral reefs. Mastering its correct usage is crucial, as it enhances your experience and ensures safety. Please follow these detailed steps:
I. Pre-Dive Preparation and Checks
1.Choosing the Right Snorkel:
Wet Snorkel: Simplest structure, lowest price. Once water enters, the user must rely solely on forceful exhalation to purge it.
Semi-Dry Snorkel: Features a splash guard or offset design at the top to effectively reduce water entry from waves, but water entering the tube still requires purging by blowing. Recommended for most recreational snorkelers.
Dry Snorkel: Equipped with a special buoyant valve at the top that automatically seals when the top is fully submerged, preventing large amounts of water from entering. Highest safety, especially suitable for beginners or in choppier waters.
Mouthpiece Comfort: Choose a soft, comfortable silicone mouthpiece that fits your mouth well and doesn't cause jaw fatigue. Test bite it personally to confirm comfort.
Tube Length and Diameter: Moderate length (usually 35-45cm). Too short increases the risk of choking; too long increases breathing resistance and dead air space. Diameter should not be too wide to minimize breathing resistance.
2.Properly Fitting the Mask and Snorkel:
First, place the mask strap around your neck or temporarily rest the mask on your forehead.
Attach the Snorkel: Securely clip the snorkel's keeper or fastener onto the left side of the mask strap (most people prefer the left, but you can choose the right side based on personal preference). Ensure the connection is stable and won't slip or detach easily.
Adjust Position: Put on and adjust your mask, ensuring a good seal. Place the snorkel mouthpiece naturally into your mouth. Gently bite down on the mouthpiece's bite tabs (usually on the top and bottom sides) with your teeth, and seal your lips tightly around the edges of the mouthpiece. Ensure the main body of the snorkel curves naturally upwards, extending above the back of your head.
Head Strap (if equipped): Some snorkels have an adjustable head strap that goes around the back of your head for added stability, preventing the mouthpiece from being easily pulled out.
3.Land Breathing Practice:
In a safe, dry place (e.g., shore), wear your mask and snorkel.
Practice steady, deep breathing through the snorkel using only your mouth. Get used to inhaling and exhaling solely through your mouth.
Simulate Purging: Practice forcefully and briefly exhaling outwards with a "poof!" sound (similar to spitting out a watermelon seed). This is the key technique for clearing water from the tube.
II. In-Water Techniques
1.Entering the Water and Initial Breathing:
Enter the water slowly. Before submerging your face, ensure the snorkel top is above the water surface.
Once your face is submerged, keep your head slightly raised so the snorkel top remains pointed upwards and above the water. Begin steady breathing through the mouthpiece using only your mouth. Always breathe only through your mouth!
2.Maintaining Snorkel Position:
While swimming, keep your body relatively horizontal (prone), with your head in a natural position or slightly raised. Avoid tilting your head too far back or down to ensure the top always stays above water.
Be aware of your surroundings to avoid hitting the snorkel against rocks, boats, or other objects.
3.Handling Minor Water Entry:
Even the best snorkels can get a small amount of water inside due to splashes, diving, or head turns. Don't panic!
Continue Normal Breathing: Small amounts of water usually stay at the bottom of the tube or below the purge valve and won't be immediately inhaled. Maintain a steady breathing rhythm.
4.Clearing Water from the Tube - Purge Technique (Core Skill!):
When you feel a significant amount of water in the tube (affecting breathing or hearing water sloshing), clear it:
Head Lift Method (Common for Wet/Semi-Dry): Lift your head, ensuring the snorkel top is completely above water and pointing slightly downwards. Forcefully and briefly blow a sharp burst of air ("Poof!") into the tube. This blast will expel most or all of the water out the top. Resume normal breathing immediately after blowing.
Blast Purge Method (Common for Dry/Semi-Dry, Highly Recommended): No need to lift your head above water! Keep your face submerged. Take a deep breath, then forcefully and briefly blast a sharp burst of air ("Poof!") into the tube. The purge valve on dry snorkels (usually located below near the mouthpiece) will open under the pressure, expelling the water. Water will also be blown out the top of semi-dry snorkels. Resume normal breathing immediately after blowing. This method is more efficient, less tiring, and a core skill you must master.
III. Diving and Surfacing (Only for Brief Dives to Observe)
1.Preparing to Dive:
First, take a deep breath.
Just before or as your face enters the water, forcefully blow out a breath of air (to clear residual air from the tube).
Hold your breath and begin your descent. Water will naturally fill the snorkel tube.
2.During the Dive:
Never attempt to inhale through the snorkel while underwater! The tube is full of water; inhaling will cause choking.
Hold your breath and enjoy the underwater view.
3.Surfacing and Resuming Breathing:
As you begin to surface, continue holding your breath.
When your head is about to break the surface (feeling the snorkel top nearing the water), forcefully and briefly blow out a sharp burst of air ("Poof!"). This blast will clear most of the water away from the top as it breaks the surface.
Once your head is completely above water, immediately blow out 1-2 more forceful breaths to ensure any remaining water inside the tube is cleared as thoroughly as possible.
Confirm Clear Airway: Only after hearing/feeling no water obstructing the tube, begin steady mouth inhalation. Never inhale sharply immediately after blowing, to avoid inhaling residual droplets which can cause coughing.
IV. Maintenance and Care
1.After Each Use:
Rinse thoroughly inside and out with fresh water, especially the mouthpiece and purge valve (if equipped), to remove salt, sand, algae, etc.
Shake out excess water.
2.Before Storage:
Dry Completely: Hang or place the snorkel in a well-ventilated area away from direct sunlight. Ensure the inside is completely dry to prevent mold growth. Never store it long-term while damp!
Regular Disinfection (Optional but Recommended): Periodically, or after shared use, soak it in a mild, diving equipment-specific disinfectant solution (diluted as per instructions), followed by thorough rinsing and drying.
3.Regular Inspection:
Before use, check the tube for cracks, aging, or deformation.
Check the mouthpiece for softness, cracks, or tears.
Check that the clip or fastener is secure.
Check the purge valve (on dry/semi-dry) opens and closes smoothly without blockages.
If any damage is found, replace it immediately. Never use a compromised snorkel.
V. Important Safety Warnings
1.Surface or Very Shallow Use Only: Snorkels are designed for surface breathing. They are strictly prohibited for scuba diving or prolonged deep dives, as this can lead to drowning.
2.Never Snorkel Alone: Always have a buddy with you.
3.Be Aware of Conditions & Weather: Avoid snorkeling in areas with strong waves, currents, poor visibility, or heavy boat traffic.
4.Be in Good Physical Condition: Do not snorkel when fatigued, under the influence of alcohol, or feeling unwell.
5.If You Choke: If you accidentally inhale water, immediately stop using the snorkel, lift your head above water, remove the mouthpiece, cough to clear your airway, and rest until fully recovered before deciding whether to continue.
6.Respect Marine Life & Environment: Do not touch or step on coral. Do not chase or feed marine life. Take all your trash with you.
Mastering the snorkel is the key to unlocking the secrets of the shallows. Remember the purge technique, stay vigilant at all times, and every dive will become a flowing spectacle. This guide is your safety foundation, and the ocean's magnificence awaits your experience—are you ready to begin your underwater journey?
Tip: Before your first open water use, practice breathing, purging, diving, and surfacing in a pool or calm, shallow area. Master these skills before heading to open water. Comfortable and safe experiences begin with thorough preparation.
