First let me say that this forum is fantastic. I've learned more about sounders here in 2 hours than anywhere else!I have a FCV 295 connected to an R209. I've heard that different frequencies work better for locating different species. Is there any rules of thumb I can follow to try and better locate fish? We do a lot of snapper fishing from 50' to 150', where in the frequency range should I be focusing my efforts.I think I've figured out how to use the dual frequency to see two different frequencies at the same time, but how much a difference between the two frequencies should I be using?
I didn't find the right solution from the Internet.
