OMS Emergency Surface Marker Buoy (SMB) with 13 kg (30 lb) lift capacity. Length is 157 cm (5'2").
Yellow in colour for maximum visibility, it features the large wording 'EMERGENCY' down the tube to signal to the surface that there is a problem below.
This OMS SMB has a point of attachment for a dive slate allowing the diver to place a message that will let the surface know what the problem is.
Featuring a manual dump valve and unique "non-air spill" openings that prevent your OMS SMB from dumping air or taking on water when it hits the surface.
