When operating the Pro Flasher in depths over
60', the bottom return will continue to rotate
beyond the "zero" line on the dial. When the
depth is over 60', the returned signal will relate
to the numbers printed on the inside of the dial.
You may notice that increased sensitivity is
necessary due to the signal loss in deeper
water. The Pro Flasher will easily track the
bottom to depths up to 120'.
MAINTAINENCE
Your Humminbird Pro Flasher depthsounder is designed to provide you with years of
trouble-free operation with virtually no maintenance. Follow the simple procedures below to
ensure that your Pro Flasher continues to deliver top performance.
If the unit comes into contact with salt spray, simply wipe the affected surfaces with a
cloth dampened in fresh water.
When cleaning the protective lens, use a chamois and non-abrasive cleaner. Do not wipe
while dirt or grease is on the lens. Be careful to avoid scratching the lens.
If your boat remains in the water for long periods of time, algae and other marine growth
can reduce the effectiveness of the transducer. Periodically clean the face of the transducer with
liquid detergent. Pivoting the transducer up in the bracket may allow better access for inspection
or cleaning.
If your boat remains out of the water for a long period of time, it may take some time to
wet the transducer when returned to the water. Small air bubbles can cling to the surface of the
transducer and interfere with proper operation. These bubbles will dissipate with time, or you may
wipe the face of the transducer with your fingers after the transducer is in the water.
Never leave your Pro Flasher unit in a closed car or trunk - the extremely high
temperatures generated in hot weather can damage the electronics.
