The Lomo Delayed SMB 2 is an open ended delayed surface marker buoy with a weighted end to keep the buoy upright.
SMB 2 is 4’2″ long / 127cm and cylindrical in shape. It is a bright orange colour, with “DIVER BELOW” printed on it. It also features an attached whistle and the SMB can be folded away neatly to fit into a BCD or pocket.
As this is a Delayed SMB, it comes with a length of line so you are able to release it from depth and its weighted end will help it stay upright when it reaches the surface.
