* Depth capacity is dependent on water salinity, bottom type, and other water conditions.

The transducer provided with the echo 200/300c/500/550c has beam angles 

of 15 and 45 degrees at 3dB. However, when this transducer is used with 

the echo device, it can detect the smallest signals up to 60 and 120 degrees. 

Shallow and deep water performance is maximized because the echo series 

shows more fish when shallow, and reaches deep to show structure and 

bottom contours.

Avoid chemical cleaners and solvents that can damage plastic components.
1.  Clean the outer casing (not the screen) of the device using a cloth 

dampened with a mild detergent solution.

2.  Wipe the device dry.

Cleaners containing ammonia will harm the anti-reflective coating.
The device is coated with a special anti-reflective coating which is very 

sensitive to skin oils, waxes, and abrasive cleaners.
1.  Apply an eyeglass lens cleaner specified as safe for anti-reflective 

coatings to the cloth.

2.  Gently wipe the screen with a soft, clean, lint-free cloth.
