This Hollis Surface Marker Buoy can be used as a delayed or standard marker buoy and it fitted with a variety of ways to inflate the buoy either on the surface or whilst diving.
Divers can inflate the SMB by either using the oral inflator, the low pressure inflator hose connector or by using self sealing opening. The SMB will automatically close the opening as pressure builds up inside the buoy to prevent the buoy 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.
The Hollis SMB is sold with a quick deploy sling pouch for convenient, slipstream rear mounting on your back plate or bcd, so you can easily pull and grab the Hollis SMB when needed.
