Hollis Closed Cell Marker Buoy- Orange
The buoy is a Closed Cell Design 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 and so as 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.
