Hollis Closed Cell Marker Buoy – Scuba Diving SMB
The Hollis Closed Cell Marker Buoy is a rugged, reliable surface marker designed for scuba divers who need a highly visible way to mark their position during ascents, safety stops and surface signalling.
Constructed from durable 300D polyester with RF-welded seams, this Hollis SMB is built to handle regular use in demanding dive environments. Its closed-cell design helps retain air after deployment, while the integrated dump valve allows expanding gas to vent during ascent and makes the buoy quick and easy to deflate after your dive.
A heavy-duty nylon webbing attachment point with a stainless steel D-ring provides a secure connection for your finger spool, dive reel or anchor line. An integrated wrist lanyard adds another convenient handling option at the surface.
