[quote RockyRaab]The consensus is that a flasher is best for ice and a fish finder is best for open water. That makes sense. A flasher stares straight down from a fixed spot while a fish finder is designed for movement.

Really? I thought a flasher was a "fish finder" too. But then, I thought that some fish finders had flashers on them too. And I never knew fish finders didn't "stare straight down" from a fixed spot. No wonder mine never shows what's under me. I wonder what happens when a fish finder is on a boat and not moving, it must quit working since its designed for movement?
I genuinely suggest you do a little studying on "sonar" 101. ALL sonar works on the same principle, whether you call it a "fish finder," "flasher", "sonar," "graph," or whatever. Measured sound waves. Ping speeds, frequencies, sensitivity, coverage areas, and other variables change. The selected transducer has more influence on the signal than anything. So does the power of the unit. The display is subject to human interpretation and user settings, whether flasher or LCD.
And I assure you that all sonars "stare straight down from a fixed spot" if the transducer is pointed straight down. They ALL shoot in the direction the transducer is pointed, and the sound wave is then bounced back to the same fixed spot, the transducer.
