Fishfinder: Do I need it?

2782 Views 11 Replies 9 Participants Last post by  NeWcS
Give me some ideas please. Has a fishfinder made a significant difference for you? Is it worth it? Are there times when it doesn't help you at all?

Does even the least expensive model give all the info I need? Depth of fish? Water Temp? What else? Will a fishfinder work in shallow water....say.....5' deep? Does it have certain limitations?

I don't know anything about this stuff.

Its kinda funny, Ive been hittin the wallys pretty good a t chatfield and havent seen but 1 or 2 on the sonar. Prolly cause at 7-10 ft deep you only see a small circle on the bottom,maybe 2 ft. or so. But I stare at the screen all the time,because the depth seems to be critical for these wallys.
