Make yourself visible on the surface using Dive Rite’s Open Bottom Surface Marker Buoy (SMB). Utilize this SMB to relay your position in the water to your dive buddy or dive boat, ensuring a safer and more enjoyable dive experience. An updated design incorporates the inflate/deflate/OPV functions into one streamlined valve. This design can either be inflated orally, using your BC hose, or by purging a second stage regulator into the bottom of the SMB. Rolls up for compact storage in a pocket or clipped off to a D-ring. Available in ANSI-certified safety orange, pink, and yellow. Incorporates a reflective logo on both sides for added visibility. Made in the USA.
