When I'm driving along watching the side imaging my boat is at the top of my screen. How far away is what's at the bottom?

When you see something 1st appear drop a marker buoy over the side keep the same speed and watch your screen. you can see how far it goes down the screen and then look back at your marker and get a good idea of how far things are back that you have passed.
Thanks!
