Humminbird Units

[inshore]

I have a hummingbird with 200/83. most of the time I run with both on. normally fish in the 200 will be red because they are in the narrow beam and in the wide beam will be blue. set your sensitivity up till you start getting a lot of clutter. run you chart speed depending on your speed usually I will set on 6 because I'm lazy. you will normally only see your drop shot in the 200 beam. when I drop shot I always turn the rts on this will show what is directly in your beam. On your di you need to really turn up the sensitivity or you won't see any returns. you will find after a little time out with the unit it will get easier and finding fish deep will be a lot easier.

good luck and good fishing.
