the 78 probably is great for the road, but it is supposed to be a marine GPS.
When we initialized our new 78's they wanted to navigate us up Rt 1. - Go figure that. When you bring up a tide station and the prompt is "go" and you click on "go" it automatically wants to navigate you to that tide station. Who in the hell wants to navigate to a tide station?
They are probably great for the road and land but for our use as far as we are concerned it has regressed from the 76Cx.
Several days ago, we did a thirty five miler putting in a route. It was an out and back route, and we put in our points and programmed it for that. We turned around about fifty feet before the turn around point, and the thing never recognized it after five miles, and kept wanting us to go back. The 76Cx would recognize that after a few hundred yards, and then recalibrate sending us to the rest of the points for the return.
