Thanks for your service! Be safe and America appreciates you.
Now as far as depth finders go. I understand radar theory, I just have a problem finding where the structure, drop off, fish, etc are in realtionship to what I see on the screen. If I show a fish at 7' does that mean he is under my boat, to the side of the boat (the beam is like an upside down ice cream cone) That is my biggest problem, but I'll use the 1/3rd rule i read earlier. I will fancast into the area I think the fish are showing.
I truly think that is my weakest area....understanding how to read my electronics. I'll keep reading this thread and hopefully we all get more educated.
