I didn't do a ton of research on models, but I did pay a little extra for more pixels (got a Humminbird 535 - 2x the vertical pixels of the lower models).Thanks guys. Any suggestions on fish finder models (xmas is almost here), i haven't really used one. All the articles say the more pixels and more power the better. From a kayaker's perspective does this still hold true?
The power figure I've seen advertised for FishFinders (the one on the order of 600 watts, 800 watts, etc) is the power shot from the transducer down toward the bottom -- not power consumed by the LCD display. You can infer a second power figure by looking at the input requirements of the unit, but that's usually listed in volts and amps, not directly in watts. (As we all remember from Ohm's law, P=IE, of course.)Power might help with screen brightness or backlight power.
