C9 BOTTOM SWITCH
The aim of the bottom switch is to give the alarm when the probe is approaching the ocean floor.
The bottom switch is an alternative to the acoustic altimeters.
The bottom switch is activated when it is released because the weight attached with a string (rope)
to the switch hits the ocean floor. The rope length sustaining the weight should not exceed 10m
and the weight should not be more than 3 kg.
Through the REDAS-5 software, it is possible to associate an audible alarm to the bottom switch
thus providing an early warning that the probe is approaching the ocean floor.
