Northstar Echo 490s trouble shooting - Betterdays123 - 09-13-2014
I originally posted a problem about my Northstar 490s.
Connected to an Airmar high speed fairing (b66)?
Suspected the transducer.
However, today I connected it to the other Airmar in hull transducer(P79) I have in the boat.
I basically got the same readings.
The sounder picture moves and it seems to be reading bottom with both, however, the sounder picture is heavily red at the top 2inches. Not sure but something is not right. Sometimes at sea the depth goes to 2ft?
It doesn't look like the demo screen at all.
Any thoughts?
I don't mind changing the in hull, but now my thought is that the Northstar Echo 490s could be bad.
Honestly a much easier swap than the transducer.
I think I can get one on eBay.
Any possibilities that I could upgrade to another unit compatible with Old Northstars?
System is 2 Northstar 6000i connected to the Northstar 490S.
