My friend And i both have echomap 93sv with livescope. His is a year newer. Neither of us have done any updates since purchace. His doesn't have the false arch ( ghost tree ) and mine does.
So just to compare pictures, I hooked my head unit to his transducer and power cord. I got a message "transducer not detected." )
Why is This, shouldn't I be able to just swap heads from one boat to another?
Both units work well on original boats.
