Hollis Closed Cell Marker Buoy
The Hollis Closed Cell Marker Buoy design is made from Durable 300-D Polyester material with Radio Frequency (RF) Welded Seams, and it also has a built-in dump valve for easily removing the air after dives so that the SMB can’t burst under pressures as it is deployed from depths.
The Hollis SMB also has a Sturdy Nylon Webbing Strap Loop with a Stainless Steel D-Ring for attachment to a Dive Reel or Spool or Anchor Line, along with a built-in Wrist Lanyard.
