Fish Finder Opinions

[randlemanboater]

I am in the market for a good fishfinder.

I would like a color unit but I no likey the prices of new color units. I had a Koden CVS 102 on my old GW and really liked it. I could tell what kind of fish we were going to catch before dropping down the bait.

I doubt I will ever find myself in water much deeper that 40 fathoms.

What are your thoughts on how many watts, single or dual frequency, what frequency, etc.......
