First pic attached below shows the power before switching on.
The second picture shows after switching the sonar on.
( I suggest right click to keep these pics open in a 2nd and 3rd window so you can toggle back and forwards to compare them. )
Notice how the battery voltage before, with the power drainage at zero, is 13.4 volts.
After switching on, the sonar starts to draw power, and immediately the battery voltage sinks a bit to 13.2 volts, but that is OK.
