Summary: I decided to go with this unit since the Lakemaster chip had the most lakes that I fish in HD. Unfortunately, that doesn't matter since the gps is useless. My location will move around on the map. That's scary stuff in low visibility conditions Or even fishing a reef that comes up out of nowhere. I ruined a prop by navigating with this unit. It will leave many trails spaced far apart even when covering the same exact water.
Great product with great features. Good price too.

Summary: Unit works great and I am very happy with the purchase. I am using it on a 21 foot Carolina Skiff. The functions are exactly what I need for the fishing I do. I was surprised at the quality of the down imaging for the price of the unit.
Summary: Awesome Fishfinder/GPS combo. It works as advertised. It's on a Triumph 17cc. The transducer reads at all speeds. I haven't used the waypoints yet, but the GPS easily tracks the boat's travels.
Summary: The G.P.S in here is just what any fisherman or fisher woman needs. It shows your routes, can mark your way point, ( you'll never get lost again) mark your fishing spots. This has great detail of the lake your on, showed my routes for the whole week, shows great structure, and detail, very easy to use, adjusts so you can see at night easier than the older ones. It's a must have that is fairly decent priced for all it has in it.
Summary: Great unit. The bigger screen is the way to go, especially if you want to glance at it while burning across the water. GPS function allows you to mark spots you want to return to with the push of a single button. Great for marking underwater structure, your own honey holes, or just a beach or other area you don't want to search for. Good solid mount and easy installation instructions.
