Thread: US2 Sonar terrova?

I have been running a Helix 10 SI with external transducer on a terrova for about a year now. I pinched the transducer cable last summer and purchased and installed a new transducer on the terrova. I have been having problems off and on with displaying sonar, DI and SI for about a month. I reset the Helix 10SI to factory defaults and it cleared up the problem until today. I called HB customer service. (Very helpful. Very Polite) but still had the same issue. I removed the transducer cable this afternoon. No apparent cuts or sharp bends. HB wants me to send the Helix 10 SI and transducer in.

I am really thinking about going with a straight Sonar only unit with mapping and use the US2 internal transducer. Considering a Helix 9 Sonar. Not sure if Chirp is all that is available or if chirp on the US2 will provide any benefit over an older non chirp Helix 9.

Also considering Lowrance or Garmin with a 9" screen Sonar only with gps map. I realize I will not have network capability with the terrova but I don't use the follow contour mode very often at all...

Anyone tried any of the above Sonar units with the US2 in the Terrova?

Remove the xducer and cabling completely from the TM and test in the water far away from the TM ...

This is the 1st step to determine if the issue is the TM or the sonar system ...
