Pluzluce 5ft Scuba Surface Marker Buoy SMB, Yellow, 98ft Spool with Double-Ended Clip and Whistle

Pluzluce 5ft Scuba Surface Marker Buoy (SMB) kit is a compact, high-visibility inflatable safety sausage that marks diver position at the surface and includes a 98ft finger spool, double-ended clip, and emergency whistle.

This all-in-one SMB package from Pluzluce is built for recreational and technical divers who need a reliable, lightweight surface marker that inflates quickly, resists puncture, and stays visible in low light or rough seas. Constructed from 210D nylon with a TPU coating, the 5-foot tube features a reflective band and clear "DIVER BELOW" marking for immediate recognition. The kit also includes a corrosion-resistant plastic finger spool with 98 feet of braided nylon line, a stainless double-ended bolt clip, a swivel to reduce tangles, and a whistle for surface signaling.

How does this SMB improve surface visibility?

The Pluzluce SMB is designed to be seen from distance and in low-light conditions. Its bright yellow fabric, reflective tape, and printed warning text give rescue teams and boaters unmistakable visual cues.

• 5-foot inflated height for greater sightlines
• Reflective band near the top boosts night and low-light visibility
• Bold “DIVER BELOW” text for instant recognition
• High-contrast yellow color to stand out against water

What materials and features make it durable and safe?

The tube uses a 210D nylon outer with a TPU coating to resist abrasion and punctures; an overpressure relief valve prevents rupture during ascent. The construction prioritizes durability without adding bulk, and the included reel components resist corrosion.

• 210D nylon + TPU coating for abrasion resistance
• Built-in overpressure relief valve to avoid bursting
• Corrosion-resistant plastic finger spool suitable for cold water
• Stainless steel double-ended bolt clip and swivel to limit tangles

How do you inflate, stow, and deploy the SMB?

Inflation is flexible: use oral inflation via the top valve or feed air from a regulator into the open bottom. The tube deflates quickly for compact storage, and the finger spool keeps line managed for fast deployment.

• Oral inflation for quick deployment during ascent
• Regulator inflation option for hands-free filling
• Fast-deflate design to pack into dive gear or pockets
• 98ft braided line wound on an ergonomic finger spool for controlled pay-out

Can this SMB handle technical diving situations?

While primarily for surface signaling, the kit’s durable fabrics, long line, and corrosion-resistant hardware make it suitable for cave, wreck, and advanced recreational diving where clear surface marking is required. Note: it is not a personal flotation device or load-bearing tool.

• Suitable for cave, wreck, drift, and travel diving
• Compact kit includes whistle for audible surface signaling
• Lightweight — about 0.99 lb (0.45 kg) — for travel and carry-on
• Not rated for weight support or rescue lifting

Who is this for? The Pluzluce SMB kit suits recreational, technical, and travel divers who want a dependable, easy-to-pack surface marker that’s fast to deploy and clearly visible. It’s ideal for photographers exiting the water, dive buddies coordinating a surface pickup, and any diver who values corrosion-resistant hardware and a tangle-reducing spool. If you need a compact safety sausage that balances durability, visibility, and convenience without the bulk, this Pluzluce kit is designed to fit into most dive setups.
