The YASI Surface Marker Buoy (SMB) is a professional-grade, high-visibility signaling device engineered to establish an absolute safety perimeter and clear line of communication with surface support vessels. Serving as your primary tactical deployment asset during ascents, safety stops, and mid-water decompression profiles, the YASI SMB features an advanced self-sealing internal baffle layout that retains full inflation volume even if the buoy is knocked flat on the surface waves. Forged from high-tensile, lightweight technical polymers and outfitted with industry-standard SOLAS-A reflective paneling, this 11.1-liter signaling column ensures maximum visual tracking across long distances, high swell states, and low-light marine environments.
Technical Safety Features
Advanced Self-Sealing Bottom Entry: Smart internal baffle structure allows for effortless inflation via a regulator second stage or oral inflator, instantly locking gas inside to prevent accidental deflation on the surface
SOLAS-A High-Intensity Reflective Tape: Premium, marine-certified SOLAS reflective panels affixed to the apex of the buoy provide maximum retroreflective return under searchlight beams for night or low-visibility tracking
Calibrated Over-Pressure Valve (OPV): Precision mechanical pressure release valve automatically exhausts expanding gas during rapid ascents from depth, preventing structural seam ruptures while allowing manual pull-dump venting
International Maritime Signaling Print: High-contrast "Diver Below" warning graphics and explicit dive flag icons are permanently sublimated into the textile matrix to maximize recognition by nearby boat traffic
Heavy-Duty Top-Mounted D-Ring: Rugged, corrosion-free plastic D-ring anchor point provides a secure attachment interface for backup slate lines, strobe markers, or surface emergency lights
Ultra-Compact Rolled Profile: Streamlined internal volume compresses down to an incredibly tight 8cm diameter, tucking away cleanly inside drysuit thigh pockets or clipping seamlessly to a technical harness configuration
