1. Introduction
Thank you for choosing the Khroom Seaview Y Full Face Snorkel Mask. This manual provides essential information for the safe and effective use, setup, operation, and maintenance of your snorkel mask. Please read it thoroughly before use and retain it for future reference.
The Seaview Y is designed to offer a natural breathing experience underwater, allowing you to breathe through both your mouth and nose. It features an intelligent CO2 safety system to ensure fresh air circulation.
2. Safety Information
WARNING: This mask is intended for snorkeling on the surface. It is not suitable for free diving or intensive swimming. Never snorkel alone. Always supervise children. Do not use if you have respiratory or cardiovascular problems.
- Ensure the mask fits properly and creates a watertight seal before entering the water.
- Do not attempt to equalize ear pressure by pinching your nose, as this is not possible with a full face mask.
- If you feel dizzy, short of breath, or uncomfortable, immediately remove the mask and exit the water.
- Always check the snorkel valve and mask seal for any damage or obstructions before each use.
- The intelligent CO2 safety system is designed to minimize residual CO2. However, proper fit and usage are crucial for optimal performance.

4. Sizing Guide
A correct fit is essential for comfort and safety. Please refer to the following guide to choose the appropriate size:
- XS: For children aged 5 and above (depending on development).
- S/M: For users up to 1.60 meters (approximately 5 feet 3 inches) in height.

If you are between S/M and L-XL sizes:

The measurement from the bridge of your nose to the bottom of your chin is not a precise indicator for this mask type. Rely on height and face shape for best fit.

5. Setup Instructions
- Attach the Snorkel Tube: Insert the snorkel tube firmly into the opening on top of the mask until it clicks into place. Ensure it is securely attached.

- Adjust the Straps: Place the mask on your face. Pull the elastic fabric straps over your head. Adjust the four straps evenly to achieve a snug, comfortable fit. The mask should seal against your face without being too tight. Avoid hair getting caught under the seal.

- Check for Seal: Before entering the water, perform a dry test. Put on the mask and inhale gently. The mask should create a slight vacuum and feel secure on your face. If you feel air leaking, readjust the straps and reposition the mask.
- GoPro Mount (Optional): If you wish to attach a GoPro camera, slide it onto the integrated mount at the top of the mask. Ensure it is securely fastened.
6. Operating Instructions
- Entering the Water: Slowly enter the water. Submerge your face to check for any leaks. If water enters, adjust the mask or exit the water to re-fit.
- Breathing: Breathe naturally through your mouth and nose. The Seaview Y mask's intelligent airflow system separates inhaled fresh air from exhaled CO2, preventing fogging and ensuring a continuous supply of fresh air.

- Snorkeling: Keep the top of the snorkel tube above the water surface. If the snorkel tube becomes submerged, the dry-top system will automatically seal to prevent water entry. When you resurface, the valve will reopen, allowing you to breathe normally.
- Clearing Water: If a small amount of water enters the mask, simply lift your head out of the water. The water will drain out through the purge valve at the bottom of the mask.
- Exiting the Water: When you are finished snorkeling, remove the mask by pulling the bottom straps away from your face and lifting the mask upwards.

7. Maintenance and Care
- Rinsing: After each use, rinse the mask thoroughly with fresh, clean water. Pay special attention to the snorkel tube and valves to remove any salt, sand, or chlorine.
- Cleaning: Use a mild soap and soft cloth to clean the mask if necessary. Avoid abrasive cleaners or brushes that could scratch the lens or damage the silicone seal.
- Drying: Allow the mask to air dry completely in a shaded area, away from direct sunlight. Ensure all components, especially the snorkel tube and valves, are dry before storage.
- Storage: Store the mask in its soft storage case to protect it from scratches and damage. Keep it in a cool, dry place, away from extreme temperatures and direct sunlight.
- Inspection: Regularly inspect the silicone seal, straps, and snorkel tube for any signs of wear, tears, or damage. Replace any damaged parts immediately.
