Hollis Signal Marker Buoys

The Hollis Signal Marker Buoy (SMB) is an essential safety device all divers should carry on every dive. The SMB is the smart way for a diver to mark their location when making safety stops, completing mandatory decompression stops, and signaling the boat if they surface a distance away from the boat. Signal Marker Buoy is a Closed Cell Design made from Durable 300-D Polyester material with Radio Frequency (RF) Welded Seams. The Hollis SMB also has a Sturdy Nylon Webbing Strap Loop with a Stainless Steel D-Ring for attachment to a reel or anchor line along with a wrist lanyard for hand-held use.
