The OMS DSMB 180cm – Narrow is a high-visibility delayed surface marker buoy designed to mark a diver’s position during ascents and safety stops in open water. Its slim 1.8-meter profile provides excellent visibility on the surface while remaining compact and easy to store when rolled up. Featuring a hybrid inflation system, it can be inflated orally, with an octopus regulator, or using a low-pressure inflator hose, offering maximum flexibility in different diving situations. The integrated duckbill valve enables quick inflation from a backup regulator, while the 12 kg buoyancy ensures the buoy remains stable and highly visible even in rough sea conditions. An overpressure valve (OPV) prevents excessive internal pressure, and the No-Lock LP connector allows fast and convenient connection during inflation, making it an ideal choice for recreational, technical, and liveaboard diving.
