I agree, I never run mine in low. I can read bottom in all hali depths in High. I have played with low a bit but really have not found any value in my fishing. Would love to hear how guys fishing here are using low. It would probably be pretty useful if your fishing swords or other suspended deep fish. I lose bottom when running in water over 500ft and there is no difference if I have it in low or high, I assume there is just too much noise running between my two screws. If I were to do it again I would just get the HW and man up and do the thru hull.
