Zizo Rainfall Graph Sonar

This is a visual rapresentation for both passive and active sonar readings, displayed on a graph where the x axis is the bearing angle to the sonar and the y axis is elapsed time.

This type of sonar is often used in submarines and require trained operators to read. If you want to easily understand how to read it I suggest you this video:

• Active & Passive mode.
  
• Active mode filters out passive readings.
  
• Active mode displays the detection distance.
  
• Active mode allows for setting the max distance the sonar ping should travel.

This comes on an example vehicle, just copy the configuration on your boat to match the one on the example.
In the microprocessor properties you can change the sonar type you are going to use

• Button On/Off to toggle on and off the sonar.
  
• Button A/P to switch between active and passive modes.
  
• Buttons + and - to adjust the active sonar ping max distance.
