Well, the sonar image on my chartplotter
has malfunctioned and the manufacturer no longer supports or will repair
this unit. (IMHO, products of this nature and cost should have better long term support, I do not consider them "disposable", but that is for another thread
) I know the problem lies within the head
unit itself and not the T-ducer or sounder (New transducer, alternate sounder box tried with same issue, problem does not occur with alternate head
unit) and replacement is not an option at this time. The unit in question is a Garmin
2010c/GSD-21/Airmar BV744v and what I'm getting is horizontal green bands about 3/8" tall across the screen
with the sonar image embedded within the middle band. (Try reading that image!
suggested a system reset, which of course wipes out all saved data within the unit, with no guarantee of success. Do any of the more electronically gifted members have an ideas? Are there any repair person/facilities outside the manufacturers for this type of equipment
? If so, any recommendations? Thanx to all!
