The good units and a GPS come in handy when you fish waters that you have not fished for years.
Just like the old days. Shoot they fished one lake biggest part of the time. Even hunted it when it was the north 40 or south 40 for that matter.
So they know the water.
But for me the good stuff is worth it. And I still can't find fish.

Now tom I am with you each and every one of them should be user friendly and let us work the way points. Not get mad at trying to swap them form on unit to the other.
