HOW THE 900 SERIES™ WORKS

Sonar technology is based on sound waves. The 900 Series™ Fishing System uses sonar to locate and define structure, bottom contour and composition, as well as depth directly below the transducer. Your 900 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 ¼ of a second. It is unlikely that your boat can "outrun" this sonar signal.

SINGLE BEAM SONAR

Your 900 Series™ 937c Combo and 931c use a 200 kHz single beam sonar system with a 20° area of coverage. Depth capability is affected by such factors as boat speed, wave action, bottom hardness, water conditions and transducer installation.

NOTE: The 937c Combo and 931c models use single beam transducers, but may be upgraded to dual beam functionality with the purchase and installation of a dual beam transducer. Contact our Customer Resource Center at either 1-800-633-1468 or visit our website at www.humminbird.com for more information.

NOTE: Your Single frequency (937c Combo or 931c model) 900 Series™ unit was shipped from the factory with a Dual frequency software configuration. Before trying to operate your unit, you will need to set your 900 Series™ to Single Beam in order for it to work properly. See Sonar Menu Tab: Transducer Select for more information.

DUALBEAM PLUS™ SONAR

Your 900 Series™ 937c DF Combo and 931c DF are shipped with a 200/50 kHz DualBeam PLUS™ sonar system with a wide (74°) area of coverage. DualBeam PLUS™ sonar returns can be blended together, viewed separately or compared side-by-side. DualBeam PLUS™ is ideal for a wide range of conditions -- from shallow to very deep water, in both fresh and salt water. Depth capability is affected by such factors as boat speed, wave action, bottom hardness, water conditions and transducer installation.
