Diving in Kenting (08-09May10) C 245-2.jpg
Qixingyan ('Seven Star Rock'), Taiwan -- My dive buddy, Ted, deploying his SMB (surface marker buoy) shortly before ascending to the water surface.
SMBs are used to indicate a divers position to the boat for pick-up. They are essential for diving at Qixingyan as surfacing divers have often drifted several hundred meters away from the dive boa. They can thus be very hard to spot from the boat, especially if there are high waves.
