Maintenance
The Advantage Dual Frequency Sonar has been designed to provide reliable, trouble-free performance for years.
Follow the maintenance tips below to ensure that your Advantage remains problem free.
1) Keep your Advantage clean and dry. Occasionally wipe unit off with a damp cloth, but be careful not to scratch
the lens covering the LCD screen. For stubborn dirt, use a mild soap and a damp cloth. NEVER USE SOLVENTS
SUCH AS PAINT THINNER, ACETONE, OR GASOLINE TO CLEAN YOUR Advantage.
2) Occasionally clean the face of the depth transducer (sensing surface) and carefully remove any marine growth.
Use a mild detergent, or 220 grit sandpaper, or crocus cloth to remove stubborn growth.
3) If the in-line fuse is blown, replace it with a 2 amp fuse. NEVER REPLACE WITH A HIGHER AMP RATING!
If the fuse continues to blow, check the polarity of your 12 VDC power source. If the polarity is correct, check with
the Technical Service Department at (831)477-4944.
4) In order to protect your transducer from water damage, paint it with one of the following brands: Interlux-
UltraCoat, Fiberglass Bottom Coat, Super Bottom Coat; Pettit-UniPoxy; Rule-Super KL, Gloss Dura Poxy. DO NOT
use a solvent based paint.
5) DO NOT allow any solvents, i.e. gasoline, acetone, to come in contact with the transducer or head unit as
these may dissolve the material.
