ricky .... Pm me your location in w ky...And a phone number..

I can let you borrow my spare XHS 9 HDSI 180T xducer..(we might be able to set up a place and time to meet)..

You will not be able to use the 800kHz frequency...but the 455 will tell you if the problem is in the xducer or the head unit...
