Depth sounder Does a depth sounder have to be in water to work? Will it measure the distance to the ground when the boat is on land for the winter?? Thanks,
The transducer has to be in the water or attached to the inside of the hull if fiberglass with no air between the hull and the transducer. It doesn't transmit thru air.
