Shawn I use them alot and fish with 45# leadcore. It works out each color out is 5' in depth so trolling in 16'-18' water two colors out puts you at 10' two and a half out you are at 15' or so and catching that fish that shows at 16-18' on the depth finder
Check your pm's I mailed you the other day and you have not read it yet
And do they work? You tell me!
