HOW TO USE A SURFACE MARKER BUOY (SMB)?

Deploying a surface marker buoy (SMB) is a common practice in diving and maritime activities to signal your presence, mark a specific location, or indicate an ascent point. Here's a step-by-step guide on how to deploy a surface marker buoy:

1. Prepare the Surface Marker Buoy (SMB):

- Ensure the SMB is properly inflated. Most SMBs have an oral inflation valve or an inflator mechanism to fill them with air.

- Attach a spool or reel with a line to the SMB. The line should be long enough to reach the surface from the desired depth. A typical length is around 30 meters (100 feet).

2. Ascend to the Desired Depth:

- When you reach the depth at which you want to deploy the SMB, ensure you are neutrally buoyant and in a stable position.

3. Attach the Line to a Secure Point:

- Find a suitable secure point to attach the line. This could be a D-ring on your BCD (buoyancy control device), a secure rock formation, or any other stable underwater structure.

- Ensure the line is properly secured, allowing the SMB to ascend vertically without getting entangled.

4. Inflate and Release the SMB:

- Hold the SMB upright and release any trapped air or water inside.

- Using the oral inflation valve or the inflator mechanism, fill the SMB with air until it is fully inflated.

- If the SMB has an open bottom, hold it tightly closed until it is inflated to prevent air from escaping.

- Once the SMB is fully inflated, release it, allowing it to ascend to the surface. Hold on to the line as it rises.

5. Monitor the SMB's Ascent:

- As the SMB ascends, maintain tension on the line to ensure it rises vertically and doesn't drift away.

- Keep an eye on the SMB to ensure it reaches the surface without any issues or entanglements.

6. Signal Surface Support:

- Once the SMB reaches the surface, you can signal surface support by giving a series of tugs on the line.

- This notifies the boat or other divers that you have successfully deployed the SMB and are ready for pickup or that you're at the designated location.

Remember, it's essential to practice deploying an SMB in controlled conditions and follow any specific instructions provided by the manufacturer or your diving training organization. Safety should always be a priority, and proper training and experience are crucial for any underwater activity. 365 Scuba teaches a SMB class for free!
