Pluzluce Scuba Surface Marker Buoy SMB 5 ft Inflatable, Black with 98 ft Finger Spool & Whistle

The Pluzluce 5ft Scuba Surface Marker Buoy (SMB) is a compact, high-visibility inflatable safety marker kit that includes a 98ft finger spool reel, double-ended clip, and emergency whistle for clear surface signaling while diving.

When you need a reliable way to mark your position at the surface, this SMB kit combines a rugged 5-foot inflatable tube with a corrosion-resistant finger reel and essential accessories. Built from reinforced nylon with a TPU coating and fitted with a pressure-relief valve, the buoy inflates quickly and resists damage from abrasion and overpressure. The kit is lightweight and designed to be stowed easily in a dive bag so you can deploy it whenever you need to signal your location to boats or surface teams.

How visible is the Pluzluce SMB from a boat or shore?

The buoy is designed to be noticed even in busy or low-light conditions. A reflective band near the top and clear "Diver Below" markings improve daytime and nighttime detection. Its five-foot height provides a tall, stable visual reference on the surface.

• 5 ft inflated height for strong visual profile
• Reflective tape near the top for low-light visibility
• Bold markings that communicate diver presence to boats

How durable and safe is the SMB for repeated use?

Constructed from 210D nylon with a TPU coating, the tube balances flexibility with puncture-resistance. An integrated overpressure relief valve prevents bursting during ascent or rapid inflation, while seams and materials are selected to withstand routine exposure to saltwater.

• 210D nylon fabric with TPU layer for abrasion resistance
• Built-in overpressure relief valve to avoid ruptures
• Good sealing for extended, repeatable deployments

How do you inflate, deflate and manage the line?

The SMB inflates easily by mouth or by using a regulator through the open base, and it deflates quickly for compact storage. The included plastic finger spool holds 98 ft of braided nylon and features a swivel connector to reduce tangles while the double-ended bolt clip offers secure attachment to your kit.

• Inflate orally or use regulator through bottom opening
• Quick-deflate for compact packing after dives
• 98 ft braided line on a corrosion-resistant finger spool with swivel

What accessories are included and how do they help?

This all-in-one set includes the SMB, a plastic finger spool with stainless steel clip, and an emergency whistle. The whistle provides a simple audible signal at the surface, while the spool and clip offer easy deployment and retrieval even with gloves on.

• Plastic finger spool engineered for gloved and bare-finger use
• Stainless steel double-ended bolt clip for secure connections
• Emergency whistle for audible surface signaling

Who is this for? The Pluzluce SMB kit is made for recreational and technical divers, snorkelers, underwater photographers, and travel divers who want a lightweight, reliable surface marker that stows compactly and performs in a range of water conditions. It’s especially useful for shore entries, drift dives, wreck and cave support where marking position to a boat or shore team matters. Note: this SMB is intended for surface marking and visibility—it's not designed to support a diver’s weight or act as a personal flotation device.
