Ive got a humming bird fish finder. It has the dual beams the 60 degree and 20 degree i need to no where to cast at when it finds a fish. Like to the back of the boat to the side the front or what? Please help THANKYOU
Read your owners manual. If your not so good at reading, look in the book where it shows a picture of a boat floating and a cone where the transponder sends its signal. since you know how the beams work, you should be able to figure out the rest.
If you're Anchored, you Cast Up Stream so that the Bait will Flow Pass the Fish Under the Boat. Or Just Drop the Line Either Side of the Boat Away From the Anchor and Line. If all Fails, "Scuba Dive"...Smile!.
A fish finder will not give exact points where to cast.
The way to use a fish finder is to see how fish are relating to structure and cover and use that info to decided how to present your lure to the area.
