9 Cathodic Protection
A common problem with magnetic sensors is that they often become an electrical path between the
well and the controller. Often, high voltages associated with cathodic protection can leak back through
the sensor to the controller, causing erratic behavior or permanent damage.
The Sasquatch has been designed such that its internal circuitry does not come in contact with the case.
This means that even if the case comes in contact with a surface that has a stray voltage; it will not be
transmitted back through the wiring to the controller.
Please do keep in mind that any shielding on the cable that is connected to the case of the Sasquatch
will act as a path for any stray voltage to travel.
