You'll spot the big ones easily on the Fishfinder 400C's crisp, ultra-bright 4" QVGA color display. A choice of dual frequency or dual beam transducers makes this a good choice for both freshwater and saltwater fishing. In the offshore setup, you'll get a true A-scope display for instantaneous sonar data. When configured for inland use (dual beam), a round flasher viewing option is provided. The 400 watt RMS dual beam version offers a wide fish-finding cone and reaches depths to 900 feet, while the 500 watt RMS dual frequency setup can go as deep as 1,500 feet. Features UltraScroll for screen updates at live-action speeds. And Garmin's plug-and-play CANet bus enables sonar data to be easily shared with compatible Garmin chartplotter displays.

Garmin 400C Fishfinder

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. Also, the unit is dual beam, but there is nothing in the documentation about when, where, or why you would want to switch between narrow and wide beams.

I give the unit 2 stars for reliability, 4 or 5 stars for operation, and 2 stars for documentation.

Garmin 400c Review

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.

Novice user and fisherman, but appears to work well

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. Color display inhances the information being presented. The unit also measures water temp and displays underwater objects (fish?) accurately. I have other Garmin devices (auto and aircraft GPS), and this seems to match their functionality and reliability. I have used my Garmin 496 in marine mode in conjunction with the finder, and they provide quite a bit of situational information.
