Last week I tested a Garmin 498 with an internal antenna. The pick up was excellent (as good as the external) here in Florida. The color definition is excellent. My only problem is the size of the screen which does not work well on my boat. I am trying to go from black/white to color. The old GPS is larger and covers the channels better on one screen.
I was thinking I could use the same GPS both north and south.
The depth sounder is not on my Winnie boat. BTW does anyone use a fish finder on Winnie?
