L750 Fishfinder: Installation and Operation Handbook
82
kHz:
“Kilo-Hertz” – a measure of frequency (For
example, 200 kHz = 200,000 oscillations per
second.)
Kick-up bracket:
A bracket which is installed on the transom of a
boat and holds the transducer in place. When the
transducer strikes an obstruction, it is designed to
release or “kick up” out of the water to prevent any
damage.
Knot:
One nautical mile per hour (1.15 statute miles per
hour).
LCD:
“Liquid Crystal Display” - A technology used to
produce flat-panel displays.
Nautical mile:
6076 feet
Port:
Left side of the boat, when facing the bow (nautical
term).
PVDF:
“Poly Vinylidene Fluoride” – A unique polymer
plastic that has the ability to convert sound waves
into electrical impulses. PVDF is used in the
optional Sidelooker transducer for excellent
detection of fish in the horizontal direction.
Range:
The depth scale for the unit. The maximum
distance the unit will be able to see at a particular
range setting.
Sensitivity:
The ability of a receiver to distinguish between
echoes of different strengths. In general, use a
higher sensitivity setting for deep water, and a
lower setting for shallow water.
Starboard:
Right side of the boat, when facing the bow
(nautical term).
Statute mile:
5280 ft.
Stern:
The rear of a boat (nautical term).
Thermocline:
A level in the water where two areas of differing
water temperature meet. Sometimes a
thermocline can reflect sonar waves and present
a false display.
