Summary: This was my first fish finder/depth finder. First I normally only fish electric motor lakes with a 14' Jon. I think that for the price this is an excellent deal. It shows the fish and the depth and temps on the water. I actually found that I was playing more with this than watching my fishing lines.
Summary: when the store didn't carry this Garman, and I read the reviews from other owners, I went on the web and did some more research. I would recommend this product to my best friend. Works great. Wish Walmart carried more (like this 140) in store.
Summary: Product was easy to install and directions were very good. Instruction manual is well done and makes for easy learning to install and operate...just make sure to plan line path and hole locations before drilling. Adjustment settings make a host of different views and scenerios possible.
