Transducer preparation
Before putting your boat in water, wipe the face of the transducer thoroughly with a
liquid detergent. This will lessen the time necessary for the transducer to have good
contact with the water. Otherwise the time required for complete "saturation" will be
lengthened and performance will be reduced.
DO NOT paint the transducer. Performance will be affected.
