I am in the market for a fishfinder. I mostly fish smaller ponds, less than 50 acres. I do occassionally fish big water. And i am a bit of tech fan. I am looking for a fishfinder with GPS capability, high pixels, trolling motor mount, and dependable for $500 or less. I am starting fresh in this search, so any opinions on manufacturers, color vs. B/W, side sonar, etc is welcome. The unit will be mounted in my v-hull bass destroyer. What do you guys like and what would you avoid. Thanks for any help. Bass Bum
