How do you guys/gals use your fish finders on the ocen?
If you stop somewhere to fish for rockfish or halibut and the fish finder does not show anythig, do you still drop the line, or not?
What about salmon, is it any use to chase salmon with fish finder? Or are you just looking for scools of fish and determine the depth with your fish finder?
I am not sure how much area(cone?) the fish finder covers on the screen, that's why I have not been able to make very good use out of it, except for checking the depth.
