ERFORMANCE
The 320 Series represents a new way of thinking about fishing electronics.
Combining state of the art electronics and paper chart recorder sonar
performance, it offers the best of the present and the past. Minimal, easy to
understand knob controls provide access to the most important features. The
320 eliminates confusion created by too many buttons and menus. High
technology, high performance, with "back to basics" operation makes the 320
the ideal choice of the serious angler.
The 320 uses sonar to locate and define underwater objects. Sonar technology
is based on sound waves sent into the water in a controlled "beam" from the
transducer. Objects within this beam reflect the sonar signal back. The 320 very
accurately measures the distance to these objects based on the time it takes for
the sonar to return. Each object (bottom, fish or structure) reflects the sonar
uniquely, providing information about its makeup. The 320 draws this returned
information on the display.
The 320 uses an extremely fast microprocessor to relay sonar information from
the transducer, enabling the unit to send and receive up to 30 sonar returns
per second to provide Real Time Sonar information. These sonar signals are
sent through a dual beam sonar system. The dual beam system combines a
wide area of bottom coverage with great bottom detail to define structure,
subtle bottom contours and suspended objects such as fish.
The 320 operates in a wide variety of water conditions, from 2' to 600'. Actual
depth capability depends on many factors such as bottom hardness, water
conditions, and transducer installation. All sonar units typically read to deeper
depths in fresh water than saltwater.

The 320 features a sophisticated Dual Beam sonar
system using two beams at the same time for
optimum performance. The combination of a wide
beam for greater area of coverage and a narrow
beam for precise detail presents true fish arches and
a detailed bottom.
