Product Description

Amazon.com Product Description

The Garmin 400C Fish Finder with Dual Beam Transducer combines high performance with a simple interface that makes it easy to locate fish wherever you go. With all the functionality you need in a base system, and a choice of transducers for multiple options depending upon your fishing environment, the 400C is a great entry-level fish finder for anybody who just wants to get out and find fish.

The Garmin 400C fish finder utilizes a crisp, ultra-bright, 4-inch, full-color QVGA display with 320 x 240 pixels of resolution that lets you easily distinguish bottom detail and fish from background structure. This unit features easy, one-touch navigation through different functions via front panel control buttons, as well as UltraScroll for screen updates at live-action speeds. The 400C also features a backlit keypad for easier operation at night, and a new night mode function that provides optimum readability in low-light conditions.

The 400C is designed to be easily adaptable to both freshwater and saltwater conditions, with a choice of dual-beam or dual-frequency transducers. This unit comes with a 400-watt (RMS), dual-beam transducer that provides you with a wide fish-finding cone for better surrounding visibility down to a depth of 900 feet. There is also a 500-watt (RMS), dual-frequency transducer available with a narrower beam that pierces the depths below your boat down to 1,500 feet. Made to be upgradeable and expandable, the Garmin 400C includes built-in CANet connectivity that enables sonar data to be shared with a compatible Garmin chartplotter as part of a larger marine system. This unit weighs 1.5 pounds, and measures just 5.72 x 5 x 2.73 inches (W x H x D) allowing it to be placed virtually anywhere.

What's in the Box
Garmin 400C fish finder, dual beam transducer, swivel mounting bracket, power and data cable, protective cover and owner's manual.

5.0 out of 5 stars Novice user and fisherman, but appears to work well, March 18, 2008

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.

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!

This review is from: Garmin Fishfinder 400C with Dual Beam Transducer (Electronics)

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.
