with the new technology on these new trolling motors, soon we wont need marker bouys just spotlock over the piles and fish.. sometimes the sattelites are off some though, I have seen this many times, where the piles were 10 feet from the gps mark, it tends to be consistant, like every pile you go to is 10 feet off from where it should be.
JESUS CHRIST IS THE WAY, THE TRUTH. AND THE LIGHT. !!!! PUT ALL YOUR TROUBLES IN JESUS HANDS, YOU WILL SEE WHAT HE CAN DO.
