That's right. And if you hit it a bunch it will freeze the unit sometimes too. Going to try the new transducer tomorrow so that can be checked off the list.

So Kosmo, if you have the DI pinging you still don't hear anything on the unit then correct? Got a PM on BBC and the guy has a Onix 8 and is pinging like crazy also. He seems to be having the same problems I am, to the point he sent his unit in and they updated his software. Really curious why yours is not doing it. Mine didn't do it at home, just when I installed it on the boat.
