Hi all,
My unit is 797C2 SI combo, firmware 5.450
I recently took the boat to the ocean. Everything worked fine until about 95FT. The unit shown depth reading at 1ft and nothing else was working properly. When I took the boat back to around 80 ft and the unit started working normal again.
Troubleshooting:
Contacted tech support while having trouble in the ocean, they walked me through all the settings and didn't resolve.
Replaced the power cable with a brand new one, bought a new battery just dedicated for the unit. Power is out of the question.
Upgraded firmware to 5.450 latest.
What else should I replace? I am thinking about buying a new transducer.
Any suggestion is appreciated.
Thanks
CMC
