The AU9 can be used either on it’s own or it can be attached to a diver surface marker
buoy/SMB (recommended); a special SMB with antenna guide loops and PLB pocket is available
through your local stockist. By attaching your AU9 plb unit into an SMB and attaching a line to the
SMB, the AU9 PLB can be used to raise the alarm from the sea bed in the event of difficulties.
2.2.4
How to use the AU9 when fitted to a surface market bouy.
1.
Diver descends.
2.
Diver gets into difficulties at depth. Activate AU9 by sliding side switch DOWN,
attach SMB to line and send AU9/SMB to surface.
3.
AU9 will arrive on surface already transmitting, pull line tight to ensure SMB
remains vertical.
4.
SARfinder on dive boat within range will activate notifying crew of an ‘SOS’
emergency. SARfinder will display direction of SOS signal and approximate
range.
