Rating: ScubaPro X-Tek Surface Marker Buoy (SMB) Review - Scuba Gear Reviews
Reviewer: Ryan R.
A little bit pricey, but its a very technical and convenient SMB nonetheless. You can use both oral or regulator to inflate and it will stay upright on the surface. For those wondering, it does comes with a small bag for storage and velcro to keep it roll up.

    1. Whats the purpose or need for a over presure relief valve for a SMB 2. Can you buy pouches separatly ? if not how would you suggest you secure it to a BC

    Bill  (Certified Scuba Instructor at

    The over pressure valve is used when using the SMB as a lift bag. It allows the diver to control the ascent of the bag. Usually you can clip a lanyard or carabiner to the SMB and then attach it to the bc.
