Thanks for the quick reply.
Here is more detail:
Ambient temperature from transduce works, but is not picking up surface speed from transducer nor is the transducer picking up down speed/temperature from probe.
I could care less about surface speed as I will get that on my fish finder, but the down speed/temperature is needed.
So it could be:
* bad transducer not picking up probe and also not feeding surface speed to head unit
* bad probe - although probe does have blinking led when metal tips are moistened
* bad head unit not receiving information (except ambient temperature from transducer)
Hard to diagnose with out a working setup to rule things out.
I worked with Fish Hawk folks who had me do a reset of the head unit and that went through the entire reset routine successfully, but still same result.
Have any other ideas/suggestions?
Thanks!
