3D Sonar
Your Matrix® Fishing System uses a six-element transducer that
transmits at 455 kHz and is capable of reaching depths of 240 ft
(75 m). Each transmitted beam is 16 degrees in width and is
symmetrical. The six beams are lined up next to each other to
provide a total coverage of 53 degrees from side to side, and 16
degrees from front to back. Using multiple narrow beams together
gives you a wide area of coverage for terrain interpretation and fish
location, without sacrificing the detail only a narrow beam can
provide. Your Matrix® Fishing System gathers information from a
continuous series of these returned signals. It then interprets this
information to create a detailed 3-dimensional view of the terrain
passing beneath your boat as you travel across the water.
2D Sonar
Your Matrix® Fishing System also has the capability of displaying
traditional 2-dimensional sonar information from either a 455 kHz
beam or an 83 kHz beam. The 455 kHz single beam has the
advantage of providing increased sonar resolution but is limited to
a depth capability of 240 ft (75 m). The 83 kHz single beam sonar
has the advantage of providing sonar information to 1000 ft
(330 m) but the sonar resolution is not as great as with the 455 kHz
single beam.
NOTE: Depth capability is affected by such factors as boat speed, wave
action, bottom hardness, water conditions and transducer installation.
