Diving safety equipment that signals 'diver below' to surface traffic, with design details that help it stay upright and be seen from a distance. That reassurance lets nervous divers and surface teams spot and respond quickly. Is the JZLiner Surface Marker Buoy the right choice for regular divers who need a rugged, easy-to-use marker?
⚡ At a Glance
- • Visibility: High-visibility orange with reflective band both sides and D-ring for night lights
- • Best for: Recreational and professional scuba divers who need clear surface marking
- • Not ideal for: Water users who do not require diver-down signalling
Open-bottom 4ft DSMB constructed from 210D nylon with a weighted block to remain upright. Comes with a stainless-steel finger spool reel, non-return inflation design and an overpressure relief valve.
Clear surface signalling - with double-sided reflective flag and D-ring
Double-sided diver-down flag includes reflective banding on both faces, and a D-ring at the top allows attachment of night lights. Reflective materials increase visibility in low light and from greater distances.
Visible markings make it easier for boat crews and shore teams to identify diver locations quickly, reducing collision risk during ascents and surface intervals.
Quick inflation and steady presentation - with open-bottom tube and weighted block
Open-bottom tube accepts air via mouth or a low-pressure BCD snorkel and uses a non-return design to lock inflation; a weighted block at the base holds the tube upright. Built-in overpressure relief releases excess pressure to prevent damage.
Fast deployment gets a marker on the surface in seconds, and upright stability keeps the flag clearly visible even in light chop.
Tidy, durable line handling - with stainless-steel finger spool reel and swivel connector
Alloy stainless-steel finger spool reel resists wear better than plastic alternatives, while the swivel connector reduces line twisting and tangles. Reel design suits the supplied 100ft line length for controlled ascent profiles.
Comfortable handling and reduced tangling lower the chance of snagged lines, making ascents smoother and safer for both diver and buddy.
