I have a couple of those from my previous dog. He started chewing on the transducer after he ate the harness for the lights (consumed it too). What an animal. Had to string the hot wire around the boat and it parked in the yard..
Here comes the blonde in me- There is a simple procedure for plug and play Smartcraft Monitors and gauges. First couple pages into the manual it says MASTER RESET- Pure Magic after that ... The gauge must have been previously powered up and it was confused as to who its new master IS.
So I put 1.2 hours on it.. Composure, I think it is done gents...
Next is a small bathroom remodel then I can go use this baby and redouble my focus on redfish and trout.
