  2. I’m not thinking when running my boat even at a low speed that i’m really seeing whats under the boat at that time …does the unit have momory and takes a little time to catch up when I stop and then see whats under me ?

    • If your chart speed is set to hi, then at slower speed, what you are seeing is right under your boat. With a slow chart speed your graph will be a litte “behind”.
