Why PADI SMB or dSMB Speciality?

As you start to venture further afield with your diving, you will quickly learn the importance of alerting people on the surface to your position underwater. A delayed Surface Marker Buoy (dSMB or SMB) is an essential piece of equipment for any diver – Whether you need to summon the boat to pick you up after a dive, find a missing buddy, ascend without a fixed reference line, warn off boat traffic or even request extra cylinders.

This course will teach you how to easily, safely and reliably deploy a dSMB; giving you the peace of mind that you are comfortable using this essential (though initially daunting) piece of equipment whenever you may need to.
