Sonar technology is based on sound waves. The Matrix TM Fishing System uses sonar to locate
and define structure, bottom contour and composition, as well as calibrate digital depth
directly below the transducer.
Your Matrix unit 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.

Your Matrix uses a dual frequency 200/83 kHz DualBeamPLUS TM
sonar system with a wide (60°) area of coverage. DualBeamPLUS TM
is optimized to show the greatest bottom definition with a narrow
(20°) beam, and the fish and structure location with a wide (60°)
beam. DualBeamPLUS
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. All sonar units
typically read to deeper depths in fresh water than in salt water. Your Matrix transducer
also comes with a temperature sensor included!

Your Matrix uses GPS (from a separate GPS receiver) and sonar capability to determine
your position, display it on a grid, and provide detailed underwater information. The
Global Positioning System (GPS) is a satellite navigation system designed and
maintained by the U.S. Department of Defense. GPS was originally intended for military
use; however, civilians may also take advantage of its highly accurate position
capabilities, typically within +/- 10 meters, depending on your GPS receiver. This means
that 95% of the time, the GPS receiver will read a location within 10 meters of your
actual position. Your GPS Receiver also uses information from WAAS (the Wide Area
Augmentation System), EGNOS (the European Geostationary Navigation Overlay
Service), and MSAS (the MTSAT Satellite Augmentation System) satellites if they are
avilable in your area.
