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......it marked fish nice until years 2-3, then that went to hell. By the 4th year the Lowrance unit would no longer function and would turn off mid troll or reset itself. Just a pain...
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. It'd be a perfect marriage if I didn't have to keep throwing water on her. Thank you Garmin.
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. It also see's my downrigger cannon balls and flasher at the depth I have them set at. Shows the fish activity around them. Couldn't ask for more than that!
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. It tells how to use the unit under various settings. However, it does not tell much, if anything, about how the user can interpret the sonar readings.
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. Because we operate on a lake that has many shallow areas, the depth and contour indication is very valuable.
