🤿 Usage Guide

1. Attach the HOTDIVE SMB04 to your spool or reel before deployment.
2. Inflate using the oral inflator or low-pressure hose at a depth of 5–10 meters.
3. Allow the SMB to ascend steadily while maintaining light tension on the line.
4. Ensure it remains upright and visible at the surface throughout your ascent.
5. Deflate, rinse, and store properly after each dive.

🧰 Maintenance Guide

• Rinse with fresh water after every dive to remove salt and sand deposits.
• Inspect inflation valves, OPV, and seams for leaks or wear regularly.
• Allow to dry fully before storage to prevent mold or mildew.
• Store rolled loosely in a cool, dry environment away from sunlight.

🛟 Safety Use Tips

• Deploy During Ascent — Always launch your SMB from 5–10m depth before surfacing to signal your position.
• Color Signaling — Yellow is for general use; Orange is typically reserved for emergency or “diver needs help” signals.
• Stay Clear of the SMB Line — Maintain a safe distance to avoid entanglement during deployment.
• Use a Reel or Finger Spool — Keeps the line controlled and SMB upright in currents.
• Train Regularly — Practice inflation and deployment in calm water before deeper dives.
• Maintain Visual Contact — Ensure the SMB remains inflated and upright until pickup or surfacing.
