Featuring closed-circuit construction, this surface marker buoy helps prevent air from escaping after inflation. Divers can inflate it at the surface for visual signaling or additional flotation, or deploy it from depth to create a visible surface reference for boat crews and other water users.\u003c\/p\u003e\n\n\u003cp\u003eConstructed from durable 200 Denier polyurethane-coated nylon, the DMB4P features a 45-inch length, 5-inch width, and approximately 8 lb lift capacity. SOLAS reflective tape across the top improves visibility during daytime and nighttime conditions, while the integrated over-pressure valve helps release excess air to prevent overinflation. It also includes a utility pocket for a finger spool or small accessories, a top nylon D-ring for attaching a dive light or slate, and a stainless steel bottom D-ring for securing a spool or reel.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhy Choose the DiveAlert DMB4P Surface Marker Buoy\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eClosed-circuit construction helps prevent air from escaping after inflation.\u003c\/li\u003e\n\u003cli\u003eCan be inflated at the surface for visual signaling or additional flotation.\u003c\/li\u003e\n\u003cli\u003eCan be deployed from depth as a surface marker to communicate a diver's location.\u003c\/li\u003e\n\u003cli\u003eSOLAS reflective tape improves visibility during daytime and nighttime conditions.\u003c\/li\u003e\n\u003cli\u003eIntegrated over-pressure valve helps prevent bursting from excess internal pressure.\u003c\/li\u003e\n\u003cli\u003eUtility pocket provides storage for a finger spool or small diving accessories.\u003c\/li\u003e\n\u003cli\u003eTop nylon D-ring allows attachment of a dive light or slate.\u003c\/li\u003e\n\u003cli\u003eStainless steel bottom D-ring provides an attachment point for a spool or reel.\u003c\/li\u003e\n\u003cli\u003eDurable 200 Denier polyurethane-coated nylon construction for repeated diving use.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eBrand: DiveAlert.\u003c\/li\u003e\n\u003cli\u003eModel: DMB4P.\u003c\/li\u003e\n\u003cli\u003eProduct type: Surface marker buoy (SMB).\u003c\/li\u003e\n\u003cli\u003eConstruction: Closed-circuit design.\u003c\/li\u003e\n\u003cli\u003eMaterial: 200 Denier polyurethane-coated nylon.\u003c\/li\u003e\n\u003cli\u003eLength: 45 inches.\u003c\/li\u003e\n\u003cli\u003eWidth: 5 inches.\u003c\/li\u003e\n\u003cli\u003eLift capacity: Approximately 8 lb.\u003c\/li\u003e\n\u003cli\u003eReflective material: SOLAS reflective tape across the top.\u003c\/li\u003e\n\u003cli\u003eSafety feature: Integrated over-pressure valve (OPV).\u003c\/li\u003e\n\u003cli\u003eStorage: Integrated utility pocket for a finger spool or small accessories.\u003c\/li\u003e\n\u003cli\u003eTop attachment: Nylon D-ring for a dive light or slate.\u003c\/li\u003e\n\u003cli\u003eBottom attachment: Stainless steel D-ring for a spool or reel.\u003c\/li\u003e\n\u003cli\u003eInflation methods: BCD low-pressure inflator hose or oral inflation.\u003c\/li\u003e\n\u003cli\u003eInflation nozzle: Plastic-tipped inflation valve.\u003c\/li\u003e\n\u003cli\u003eAvailable colors: Orange or yellow.\u003c\/li\u003e\n\u003cli\u003eApplication: Underwater deployment, surface signaling, and additional flotation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eEasy Inflation and Deployment\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe DiveAlert DMB4P offers convenient inflation options for different diving situations.
