Lots have them, some won't because of cost & then there are some like my buddy & his wife that are very good crappie fishermen that would rather blow their money on playing bingo & fighting chickens & complain saying you can't compete with the guys who have livescope even though they won the amateur side of two out of three crappie usa tournaments they fished with nothing but a 4" humminbird pihrana depth finder. I know i wouldn't be fishing for them or trying different styles of catching them without livescope at all. I'm very happy with it myself & have officially became a perch jerker.
