Setting the FrontVü Depth Alarm


The FrontVü depth alarm is a tool for situational awareness only, and may not prevent groundings in all circumstances. It is the obligation of the vessel operator to ensure safe operation of the vessel.


The Beeper setting must be turned on to make alarms audible (Sounds and Display Settings). Failure to set audible alarms could lead to injury or property damage.

This alarm is available only with Panoptix™ FrontVü transducers.

You can set an alarm to sound when the depth is below a specified level. For best results, you should set the bow offset when using the front collision alarm (Setting the Bow Offset).

  1. From the FrontVü sonar view, select Menu > FrontVü Alarm.
  2. Select On.
  3. Enter the depth at which the alarm is triggered, and select Done.

On the FrontVü screen, a depth line shows the depth at which the alarm is set. The line is green when you are in a safe depth. The line turns yellow when you are going faster than the forward range gives you time to react (10 seconds). It turns red and sounds an alarm when the system detects an obstruction or the depth is less than the entered value.


The ability to effectively avoid running aground with FrontVü sonar decreases as your speed rises above 8 knots.
