HOW SONAR WORKS
HOW SONAR WORKS
Your Teleflex Sonar unit uses sonar
to locate and define underwater
objects, define the bottom terrain, as
well as determine distance.
Sonar technology is based on sound
waves. Your sonar unit sends out a
sound wave signal. With this signal it
determines distance by measuring
the time between the transmission
of the sound wave and when the
sound wave is reflected off an
object. Your sonar 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
600' (185m) and back again in less than
¹⁄₄
of a second. It is unlikely that
your boat can "outrun" this sonar signal.
The 100ID series is a single frequency, single beam unit, and generates a 16°
symmetrical cone of sonar coverage at 200kHz. The 16° coverage shows
excellent bottom detail with a greater depth capability than wider beams.
The sonar return shows the most current information at the right of the
screen and draws a history of the information as it scrolls across to the left.
Actual depth capability depends on factors such as bottom hardness,
water conditions, and transducer installation. Units will typically read to
deeper depths in fresh water than in salt water.
