The sound pulses are transmitted at various frequencies
depending on the application. Very high frequencies
(455kHz) are used for greatest definition but the
operating depth is limited. High frequencies (200kHz)
are commonly used on consumer sonar and provide a
good balance between depth performance and
resolution. Low frequencies (83kHz) are typically used
to achieve greater depth capability.
The power output is the amount of energy generated by
the sonar transmitter. It is commonly measured using
two methods:
• Root Mean Square (RMS) measures power output
over the entire transmit cycle.
• Peak to Peak measures power output at the highest
points.
The benefits of increased power output are the ability to
detect smaller targets at greater distances, ability to
overcome noise, better high speed performance and
enhanced depth capability.
Single Beam Sonar
Your 100 Series™ Fishing System uses a 200 kHz Single
Beam sonar system with a 20° area of coverage. The 20°
beam is focused on the bottom, to show you structure,
weeds and cover.
