The Hollis SMB with Sling Pouch can be used as a delayed SMB or standard marker buoy. It comes with a quick-deploy sling pouch for convenient slipstream rear mounting on your backplate or BCD, so you can easily pull and grab the Hollis SMB when needed.

You can inflate the 1.8m long Hollis SMB in three ways: using the oral inflator, the inflator hose connector, or a self-sealing opening.

The SMB will automatically close the opening as pressure builds up inside to prevent the SMB from deflating once it reaches the surface.

To stop the buoy from rupturing during the ascent, the pull dump also acts as an over-pressurisation valve to release excess gas.
