Ask any angler and they will tell you that some spots just look and feel fishier than others, it relates to fisherman’s instinct. Instinct is the main thing that Hunter Jones and I use on the river when we don’t see fish on the sonar. If we feel confident in a spot, we will fish it.
Do not be afraid to try a new area, new spot or new technique. There is no such thing as a stupid spot to fish or a stupid way to fish. When a fisherman starts thinking that way they are not learning.
Time on the water develops that intuitive knowledge that compliments the electronics to help us know where to fish and where not to.
If you use your instincts, in combination with your skills, you will probably improve your catching.
