Aqua Tec Delayed Mark SMB is a very popular Delayed SMB. It is usually inflated prior to leaving the bottom, allowing air expansion to fully inflate the SMB on its assent. A large capacity Delayed SMB when fully inflated will support diver during decompression.
Manufactured in the same material and to the size of Dive Mark SMBs it is open ended with a throat restriction at the bottom of the tube. This restricts the air from escaping should the line be released. A Velcro strap retains SMB when rolled up prior to deployment.
The Delayed Mark will provide up to 15-16 Kg of positive buoyancy at the surface.
