Lowrance built a GREAT reputation for customer service. They had a lady named Sue who would bend over backwards to help you out if you had a issue. Not sure if she's still there or not, but the few times I dealt with her, she was great. She once shipped a replacement unit overnight to my boat dealer, before I had even shipped back my damaged unit, so I wouldn't miss a Tx. Things like that keep me buying Lowrance.
Sue left Lowrance in a way the most felt unfairly...She was the one that kept most coming back to Lowrance. If you didn't deal with Sue, it was a crap shoot. Lowrance customer service has been a crap shoot at best, for a few years now. When you have trouble with you Lowrance, they will most likey not repair it. YOu will have to send in $60 just to have them look at it, and they will tell you it is out dated and they no longer support it. But will sell you a newer version for a discounted price....Yes, even with the $2K plus units, they do this with.
I'm not the only one with these issues....Google Lowrance custormer service. Check out walleyecentral.com in the "electroins forum, for some more info.
