My post is late to the party but here is my 2cents worth. I have had Lowrance, no problems. I still have a hummingbird, no problems. I put the Garmin 73dv up front last year and of all of them, the ease of use, clarity and detail, the Garmin is by FAR my favorite. My take is it's like the Ford/ Chevy debate. They ALL make a great product and I'm sure whichever you choose will be what is right for you. Good luck!
