Boats and currents are two common factors associated with many dive sites. Boaters don’t always recognize that divers are in the area and current can carry you further than expected. Launching a delayed surface marker buoy (DSMB) before you surface can alert others to your location in advance of your ascent. Adding another layer of safety, you can also use the DSMB line to complete your safety stop, which is advantageous in a current or when there are no other visual references.
Take this course to learn all about the beneficial uses of a DSMB.
