Surface marker buoy for diving that improves surface safety, the JZLiner DSMB Surface Marker Buoy uses high-visibility orange fabric and double-sided reflective bands. That reassurance helps dive teams and boat crews spot ascents and drift positions quickly. Is the build and inflation method robust enough for regular open-water use?
⚡ At a Glance
- • Visibility: High-visibility orange with double-sided reflective band for easy sighting
- • Best for: Recreational and technical divers needing clear surface signalling during ascents
- • Not ideal for: Divers who prefer ultra-compact or non-reel marker solutions
6ft DSMB constructed from steady 210D nylon with an open-bottom tube and weighted block. Includes a 100ft alloy stainless steel finger spool reel with swivel connector and a built-in overpressure relief valve.
Easy spotting on the surface - with double-sided reflective band
Reflective bands placed on both sides of the tube, combined with bright orange 210D nylon fabric, increase contrast against sea and sky. A D-ring at the top allows attachment of night lights for low-light visibility.
Clear visual signalling to vessels and surface teams, improving safety during ascents and drift dives. Practical for both day and night operations when a light is attached.
Stable deployment and upright floatation - thanks to weighted block and open-bottom design
An internal weighted block at the tube base keeps the marker upright while the open-bottom configuration allows air to be retained for buoyancy. The non-return design prevents accidental deflation after inflation.
Marker stays vertical in moderate currents, making it easier to spot and maintain position. Simple handling means quicker deployment during safety stops and surface intervals.
Durable and safer inflation - with 210D nylon, overpressure relief valve and robust reel
Constructed from rupture-resistant 210D nylon, with a built-in overpressure relief valve that vents excess inflation. The supplied finger spool reel is alloy/stainless-steel with a swivel connector to reduce line twist.
Rugged construction reduces risk of tears and over-inflation damage, while a durable reel resists wear and prevents tangles. Suited to regular use where reliability matters.
✨ The 4 Key Reasons for JZLiner DSMB Surface Marker Buoy
- Stainless steel finger spool reel — Prevents line tangles and resists wear over time
- Weighted base block — Keeps marker upright in waves and drifting currents
- Multiple inflation options — Allows mouth, low-pressure BCD or quick automatic inflation
- Built-in overpressure relief valve — Releases excess pressure to reduce rupture risk during inflation

❓ Frequently Asked Questions
Q: How do I inflate the marker buoy?
A: Use mouth inflation, a low-pressure BCD snorkel feed, or the automatic method mentioned; the non-return design helps retain air after inflation.
Q: Does it include a reel and line?
A: Yes, a 100ft alloy stainless-steel finger spool reel is included, with a swivel connector to help prevent line tangling and twisting.
Q: What makes it durable and safe?
A: Construction uses steady 210D nylon fabric, a built-in overpressure relief valve and a weighted block to keep the buoy upright and reduce rupture risk.
🏆 Our Verdict
Perfect for divers who need a high-visibility, rugged DSMB for regular open-water and drift dives. The combination of 210D nylon, reflective bands, a weighted base and a stainless-steel finger spool reel makes surface signalling reliable and straightforward. While choices vary by diver preference, the construction and safety features suggest good long-term value for frequent use.
