    Default GPSMAP 178C

    Product Manufacturer: Garmin
    The GPSMAP 178C features a built-in worldwide marine basemap and accepts BlueChart® offshore marine cartography, featuring detailed depth contours, inter-tidal zones, wrecks, navaids, and many other points of interest. For small-water anglers, the 178C is compatible with MapSource Recreational Lakes with Fishing Hot Spots, featuring fishing areas, boat ramps, marinas, and hazards for hundreds of popular U.S. and Canadian lakes. You can use compatible preprogrammed data cards, which insert easily into the slot on the front of the plotter.

    The 178C comes with a built-in sounder with Garmin’s exclusive See-Thru® fish targeting technology. The sounder features adjustable range, gain, zoom and bottom lock. It also has new digital display technology that offers an easy-to-read, semi-transparent digital readout so you can see sonar images "behind" the data.

    Price Paid: 600
    Recommended: yes
    Cons: small screen
    Pros: Easy to use, inexpensive
    This is a great entry level sounder. The screen is small but I was interested in saving "real-estate" on my 19' Center Console boat. It's fairly easy to use but feature rich. I bought the blue charts map and card for my area and probably wouldn't do it again as they aren't accurate enough for navigation in the sound and channels and they don't have much information for the ocean. I do like the PC software program (mapsource) that came with the bluechart (can be purchased seperately too) - it makes managment of way points a breeze - I load them up on my PC then just download them to the card and plug them into the GPS unit.
