Summary: I used to own the Lowrance X102c, it lasted approximately 4 years. The unit was taken immaculate care of, never left in the rain, removed from boat for traveling, padded when traveling, etc.etc....it would only mark the down-rigger ball the first year, then never again.....
Summary: I was looking for mermaids and I saw a sudden flash on my Garmin 400C. I dipped my net down and caught something large. It was a beautiful Mermaid. Once on my boat she shed her tail and grew pale. I gave her mouth to mouth for several hours, then took her home and married her.
Summary: I snooped through a lot reviews, I had specific requirements and this 400c does exactly what I wanted at a great price. I also have a Garmin 478 chart plotter that interacts with this 400c, I am impressed with the color definition.
Summary: I had to return the first 400C that I installed. It stopped working after 2 days. The replacement works fine, but I wonder about the long-term reliability. The fish-finding performance of the unit appears to be very good. No complaints here. The documentation is very basic.
Summary: The Garmin is a good unit. I replaced a non functioning Lowrance unit with the Garmin. It does not have the detail or sensitivity the Lowrance unit had, but I needed a quick cheap replacement. I would wait and spend the extra money for a good Lowrance Sonar.

Summary: I purchased this last year, and it has been installed on a pontoon boat for a full season. This unit replaced an older finder that was already installed when I bought the boat. Installation was relatively easy with the boat on its trailer.
