FF question.

Hummingbird 787ci. New GPS puck, brand new ducer. Getting bad depth readings n although I know I was going it a straight line n verified by my 997, it showed me going it circles n the depth reading wasn't happning. Just kept blinking or reading 400-800 feet in 12-25 fow. Is the 787 shot? I restored defaults 4-5 times no help. Worked great the first hour then the problems started. Yes, I unhooked it, turned it off n on. Everything you could think of. I bought it used 4-5 years ago

Ask over on the electronics board......several guys over there pretty sharp on this stuff.

First thing Don, go into your settings and make sure you have the right transducer selected. Then go into your system and tell it you have a GPS attached.

:hesaid

Thanks try that next time I'm on the water. I did a factory default restore 3-4 times, that should have set it right

Not necessarily. Should be able to check the settings in the drive way.

Cray is right...you can do it in your yard
