I can't leave home without my 997. I spend a LOT of time looking at it for information....in fact the longer I have owned it the more time I spend with it after learning what it can do and how to use it without looking at the book. That being said.....one of the best Crappie fishermen I know (an ol'timer troller.....in fact the guy that taught both me and Blue Thunder) doesn't even use a depth finder. I guess he commercial fished for so many years that he just instinctively knows what is under the boat and what the fish are doing. Take him to any worthwhile body of water within 50 miles of here and he can draw you a topo map....knows where the channels, creeks, brushtops, ect are all at....like a photographic memory, LOL!!! I've fish beside him in another boat many times when he will tell me the depth and structure at various spots...he ain't never been wrong yet! It gives him a distinct advantage because when I am glancing at the screen for waypoints or whatever, his eyes are glued to those rod tips like a hawk!
