As all good divers will testify every diver out there should be carrying their own scuba diving SMB or scuba diving Delayed SMB with them at all times. Anytime you dive in areas of boat traffic or on off-shore wrecks the use of a scuba diving SMB or scuba diving delayed SMB can be a massive aid to safety and diver location
Although a traditional scuba diving SMB can be useful we tend to find that most divers now opt for a scuba diving delayed SMB, either in self inflating or standard format design, that offers a wider scope for use
