I just found this thread on the Right side of my Screen and have several things to say --- First have 3 float markers in the boat , Paint one a different color. Drop the colored one first and it will help you close in on the spot. unless the fish is in a deep place most times the fish will shut down when the boat keeps going over the spot.. With it properly marked , go back and pick up the colored marker , then go hunt in the area for a second place in the area to drop it in case the fish in the first spot are not biting.. Next -- go to the ELECTRONICS TITLE on our CDC forum ,,, There is Two Tons of Info and help there ... Third Go to the U-Tube for Many hours of answers of the just asked questions. The States In the deep South also make lots of good Post that help
