Bonding of bronze tranducer required?

[Creekwood]

I just installed a bronze B60 through hull transducer. Does it need to be tied into the bonding system or is it OK to leave it as is?

If it were me and my boat was 24/7 in the water, then yes.

You can check to see if you need to by putting a volt meter between the bonding system and the transducer. Anything above a few mili-volts and you must bond them.

It all depends on how bad your dock wiring is for the most part.
