Summary: Returned it. Print ad said it was a "Fish Finder GPS" It was all fish finder, no GPS. Can't answer questions below, nover got past the instructions followed by a call to Best Buy to confirm it did not have GPS capability.
Summary: Thought about Lorance and Eagle, along with others but I had a Garmin GPS/Fishfinder when I lived on the Gulf and it worked fine so decided to stay with Garmin. Sure glad I did. Installed easy and the screen is easy to read during a bright sunny day. For the money and you want color, this Garmin Echo 500C is what you want. And Wal-Mart pricing was right on.
Summary: The screen is a great size and can read it in full sunlight no problem. It has lots of settings to choose from to accommodate what you are targeting, the mounting is simple and affective and I like the fact that the finder is removable with out any wrenches. Have only used it a couple of times but has got me in the right area to catch the fish. Would recommend this product for sure.
