The two sides are glued and sealed and then stitched for reinforcement. 2、Safety Explosion Proof Valve: Equipped with an explosion proof valve, if the gas is overcharged, the gas will leak from the explosion proof valve, speeding up the deflation, and will not blow up like a buoy. The explosion proof valve can also protect the buoy from exploding underwater. 3、Double Sided Reflective Strips: Reflective strips are designed on the surface marker buoy, which can reflect light well, strengthen warnings, and provide a layer of protection for diving safety. 4、Hook and Loop and Rubber Band Design at the Bottom: The surface marker signal tube is designed with hook and loop and rubber bands, which are double fixed, reduce the volume, convenient to carry, and also provide safety guarantee for diving. 5、Stainless Steel D Ring: The top of the marker buoy is designed with a stainless steel D ring, which is convenient to hang on the D ring of the BCD during diving, which can greatly reduce the burden on the hand. Secondly, the D ring can also hang a flashlight or signal light, which is convenient and fast. <div class="wang-edit-text"><p class="wang-edit-text"><p class="wang-edit-text"> Item Type: Scuba Diving Surface Marker Buoy Material: 210D Nylon Product Size: 120x15cm / 47.2x5.9in Product Weight: Approx. 325g / 11.5oz Main Functions: Top D ring, reflective band, vent valve, inflation nozzle, secondary head inflation, one way membrane, bottom weight block, storage D ring, storage rubber band, storage hook and loop, and it can also be used with spools <p class="wang-edit-text"><style> .wang-edit-text{ font-family:'Arial' !important; } .wang-edit-text table { border-top: 1px solid #000; border-left: 1px solid #000; } .wang-edit-text table td, .wang-edit-text table th { border-bottom: 1px solid #000; border-right: 1px solid #000; padding: 3px 5px; } .wang-edit-text table th { text-align: center; }</style> </div> 1 x&nbsp;Scuba&nbsp;Diving Surface&nbsp;Marker&nbsp;Buoy Satisfaction - Our customers are our top priority.
