Mares XR SMB
The Mares XR SMB is a safety marker bouy that is used in emergency situations generally to gain attention when in the water. They can also be used to mark a spot where you may be coming up from a dive, or to send a message to the surface. It is made with a durable welded and double stitched material that is bright orange for maximum visibility. The XR SMB is 15cm wide and 1.8 metres in length. There is a transparent window on the top which can be used to send a message to the surface or to put a glow stick in if you are night diving. Below that on the bouy are 2 reflective strips which allow emergency services to see it in the dark. At the bottom of the bouy is a one way over flow valve that allows and gas to escape when being sent to the surface and expanding. This prevents the bouy from over filing and potentially popping from pressure. A oral inflate s below the one way valve which is how you fill the SMB however you can also use the low inflator hose attachment from your BCD. Hanging on the bottom is a stainless steel D-ring which is perfect for attaching your reel to.
