I just traded boats and the new model has a LOwrance-hds-5 on the console. I have been a hummingbird man all my life and this thing is just greek to me. And yes I've heard the term just play with it and I am still lost. Does there exist anywhere a you-tube or disk you can buy to learn this stuff(for dummies) Thanks and my second question is there anyway to transfer my GPS waypoint locations from one model to the other?
