How Sonar Works
Sonar technology is based on sound waves. The Matrix Fishing System uses sonar to locate and define
structure, bottom contour and composition, as well as depth directly below the transducer.
Your Matrix 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.
DualBeam PLUS™ Sonar
Your Matrix 97 Fishing System is shipped with a 200/83 kHz DualBeam
PLUS
TM
sonar system with a wide (60°) area of coverage. DualBeam PLUS
TM
sonar returns can be blended together, viewed separately or compared
side-by-side. DualBeam PLUS
TM
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.
QuadraBeam™ Sonar
(with Optional-Purchase QuadraBeam
TM
Transducer)
Your Matrix 97 Fishing System also supports QuadraBeam™ sonar with
the purchase of an additional QuadraBeam™ transducer. QuadraBeam™
sonar provides an extremely wide 90° area of coverage. QuadraBeam™
starts with two 45° 455 kHz beams for a continuous 90° of
uninterrupted side to side coverage to 160 feet. These Side Structure
locating beams reveal fish and structure to the left and right of your
boat near the bottom. For structure directly below your boat,
Quadrabeam™ uses DualBeam PLUS™ technology.
