WEEE compliance may not be required in your location for electrical & electronic equipment  
(EEE), nor may it be required for EEE designed and intended as fixed or temporary  
installation in transportation vehicles such as automobiles, aircraft, and boats. In some  
European Union member states, these vehicles are considered outside of the scope of the  
Directive, and EEE for those applications can be considered excluded from the WEEE  
Directive requirement.  
This symbol (WEEE wheelie bin) on product indicates the product must not be  
disposed of with other household refuse. It must be disposed of and collected for  
recycling and recovery of waste EEE. Humminbird® will mark all EEE products in  
accordance with the WEEE Directive. It is our goal to comply in the collection,  
treatment, recovery, and environmentally sound disposal of those products; however, these  
requirements do vary within European Union member states. For more information about  
where you should dispose of your waste equipment for recycling and recovery and/or your  
European Union member state requirements, please contact your dealer or distributor from  
which your product was purchased.

How Sonar Works  
Sonar technology is based on sound waves. The 700 Series™ Fishing System  
uses sonar to locate and define structure, bottom contour and composition, as  
well as depth directly below the transducer.  
Your 700 Series™ Fishing System sends a sound wave signal and determines  
distance by measuring the time between the transmission of the sound wave  
and when the sound wave is reflected off of an object; it then uses the reflected  
signal to interpret location, size, and composition of an object.  
Sonar is very fast. A sound wave can travel from the surface to a depth of  
240 ft (70 m) and back again in less than 1/4 of a second. It is unlikely that your  
boat can “outrun“ this sonar signal.  
SONAR is an acronym for SOund and  
NAvigation Ranging. Sonar utilizes precision  
sound pulses or “pings“ which are emitted  
into the water in a teardrop-shaped beam.  
The sound pulses “echo“ back from objects  
in the water such as the bottom, fish, and  
other submerged objects. The returned  
echoes are displayed on the LCD screen.  
Each time a new echo is received, the old  
echoes are moved across the LCD, creating a  
scrolling effect.  
How Sonar Works  
1
 
When all the echoes are viewed side by side, an  
easy to interpret “graph“ of the bottom, fish, and  
structure appears.  
The sound pulses are transmitted at various  
frequencies depending on the application. Very  
high frequencies (455 kHz) are used for greatest  
definition but the operating depth is limited. High  
frequencies (200 kHz) are commonly used on  
consumer sonar and provide a good balance  
between depth performance and resolution. Low  
frequencies (83 kHz) are typically used to achieve  
greater depth capability.  
The power output is the amount of energy  
generated by the sonar transmitter. It is commonly  
measured using two methods:  
• Root Mean Square (RMS) measures power
