This Closed Circuit Hollis SMB is a great addition to your set of dive gear. For your own safety, it is advisable to always carry a Surface Marker Buoy with you on every dive. Especially, if you dive in areas with frequent boat traffic! Simply deploy your SMB before surfacing and the boat captains will know that there are divers underneath the surface.

This Hollis SMB comes in a bright orange colour. Its fluorescent colour gets the attention of oncoming traffic easily. The closed-cell design, makes it a great delayed surface marker to deploy during your safety stop. Make sure to practice deploying the SMB underwater under the supervision of a professional.
