for the longest time,i would advise clients not to purchase lowrance products - due to their problems and lack of any kind of customer support...
with all that:
in the last few years,the company went through a bunch of changes - all for the better ! i had a problem with a unit on my own boat - it was on it,when i purchased - the unit was out of warranty,and,it wasn't to be sent back to the factory for repair - lowrance went out of their way,and sent me,free of any charge,a complete unit - the new upgraded unit - complete,with 'ducer and gps antenna...that unit has worked trouble free for the last 2 seasons - i can honestly tell you,it's probably the best sonar set up i have ever used,and trust me,i've used and installed them all...
i have seen absolutley no problems with the newer lowrance units - i would definatley reccomend them...
