The image will always be behind, what is on the leading edge is what you justed passed over, Plus the GPS is not WAAS, it could be off at least 8 to 10 feet. WAAS get you
with in 3 feet. The next day you go, the spot might be right on and the next day off again. It is not that pin point, just use the waypoint to get you to the area and SI to pin point it for each day.
