Humminbird 587/597 question
How to get all the nearby waypoints to show on GPS screen? Would like to look at the screen and pick any waypoint and click on GoTo, and find the brush pile. I used the big engine and looked bach and forth for some sign of brush pile. Yesterday I tried locating Corp of Eng. brush piles with this unit and not happy with system. Have the on line manual for these units but need more help. What setting for arriving alarm? Any other would help as have hard time with new toys.
