The OMS Hybrid SMB (Surface Marker Buoy) is a versatile safety device designed for divers, offering multiple inflation methods for reliability underwater. Its self-sealing open bottom allows inflation via a regulator’s second stage, while the No-Lock LP inflator works with any drysuit or low-pressure hose—plus oral inflation as a backup. Available in high-visibility orange or yellow, this 3.3-foot (1-meter) SMB features an Over Pressure Release Valve for safety and a closed bottom to prevent accidental deflation. Built with a stainless steel D-ring for line attachment and a nylon loop for easy stowage, this compact buoy is ideal for signaling and emergency use. Divers should practice deployment under professional guidance for optimal performance.
