Any depth finder/sonar gurus out there that can shed some light on this?
Thanks
Peak to peak watts RMS (rout mean square) us just a way of expressing the power of the unit (sine wave). Unless you are fishing in the ocean and need very deep coverage, you do not need the high power units. For instance, I have a Lowrance X125 on my bow and it is rated at 2400 watts. This is more than enough power to see everything on the bottom. A higher pixle count is more important as it will give you better resolution.
