Jerry, I'm glad you were brave enought to write about this subject, not many
peolpe understand it at all, including me.
Now afew years ago my friend and myself did a so called test on my finder
and we were at the bank in three feet of water, holding my boat still and my
fish finder was scrolling fish and structure under the boat. I know there was no structure under the boat, I took a pole and went under the boat and found
nothing.......
And I had the finder in the right mode.
And how do you set the scroll speed ?, why are the fish not swiming toward
the the boat from the front or back?, what about tree leafs floating in the water?
It made me think about when America landing on the moon and played golf,
mybe that was a hollywood set to look that way so Russian government would go broke trying to catch up in the space race, which they did...
