I like the PiranhaMax 20 and the Fisheasy 245 DS. They are about the same, but the Fisheasy is 4 time more energivore (176ma against 40ma) so I think I will buy the Piranhamax 20. Do you see some reasons I would be better with the Fisheasy?

I'm looking at an upgrade from my 240Blue Garmin. It is dual frequency (50khz & 200khz) and am wondering if I really need "dual frequency" if I upgrade? Or would a single frequency give me better resolution?
Do I really need an upgrade?

I've read that peak-to-peak power is a measure of how powerful a depth finder is and that we should look for units with 1500 watts and higher as a general rule. The smaller color units (like the Eagle FishEasy 320C), though, advertise only around 800 watts.
Does that mean that these wouldn't have very good sharpness or detail?

Is the Humminbird 565 well suited for small pond and reservoir fishing? Also, when it shows a fish, is that fish directly below the boat or behind it?
Are the fish below the boat?

If you own a fish finder be so kind as to fill out the form on the page, so we can let other owners know how you feel about your fishfinder. Wouldn't it be nice to know and share this information before you purchased your fish finder or if there is a problem that can be easily solved before having to send your fish finder back to the manufacturer and find out there was nothing wrong and you wasted several weeks of fishing time.
