Summary: I love this chartplotter/fishfinder and have 3. What I like so much about this GPS over others is how easy it is to use. I've owned other models and used most every one made, but this is the easiest to use, allows you to customize the data that you want displayed, and requires very few keystrokes.
You appreciate a unit that beeps right before strikes occur. WOW!

Summary: This GPSMAP was the top of the line during its intro. Sharp 320 x 320 graphics. Everyone buys the approx $125 bluechart for their specific geographic area. Mine Jersey to NY including ICW and Delaware Bay. This is an excellant fishing machine able to connect to multiple different transducers. While I own a 178 all attachments will cross over to the 178C. MAIN NEGATIVE ITEM to all current and future owners.
Summary: The Garmin 178 gps was shipped fast, I was dissapointed it did not come with a bracket!!! or an antena, I guess it is thier way to make you spend more money, It should at LEAST have had a bracket to mount the thing on!!
Summary: this item doesn't come with antena for gps, no mounting bracket or transducer. not to mention this is a outdated product that garmin doesn't sell anymore all these items will cost you over 200.00 dollars so you would be better spending 500 dollars for a new updated one with color screen that come with everything
