Today's boat electronics help keep you safe, communicate, and find fish. The truth is you can go fishing and not using many add on electronics.

There are many features available when looking at Depth Finders
. There are also many different levels of clarity to choose from. Older models do a nice job of identifying the depth or bottom of the lake, but new models offer more clarity, color, and many will combine depth reading alongside of GPS readings. Todays models offer side imaging, high definition, down imaging and also links to many of the modern trolling motors in order to travel along a shoreline at a specific depth.
Will you need a Boat GPS - Marine Navigation
on your fishing outing? The bigger the water, the more you can use these in order to avoid shallow areas and hidden rocks and/or trees. You can use a hand held unit or one combined with your depth finder. Some of these units also offer detailed (one foot contour advertised) mapping of the bottoms of the most popular lakes in the US and Canada. Some modern units also offer mapping feature that actually maps the contour as you pass over the lake and saves to your memory.
