Cannot Obtain Deep Reading If mounted inside boat, be sure transducer is properly installed with fiberglass or epoxy resin. If transducer is inside the hull and is not bonded to the hull, the area must be filled with clean water, free of oil.
Be sure transducer is pointing as straight down as possible with boat in the water.
Proper Operation of Depth Sounder Noise rejection control should be at a minimum setting which will eliminate any electrical noises which are shown as erratic and random flashes on the depth sounder.
Sensitivity control should be at a maximum setting just creating a double echo on your depth sounder. Think of the sensitivity control as the volume control on your radio - the deeper the water, the more control (clockwise) required.
