frequency, plus the ability to run the selectable pulse
lengths Short1, Short2 and STD Long.- In addition, they have the ability to run selectable
Time Varied Gain (TVG) for both low and high
frequency. TVG is an excellent tool for deep-dropping
as turning it to high will amplify the Gain to concentrate
on the bottom, thereby reducing surface clutter and
returning the most Gain detail available. - Their minute marking tool is awesome for deep-
water fishing as it shows the distance between the
returns. This enables you to know how long it takes
for images to display onscreen, which is helpful when
linking it to pulse length. - The matching Furuno 82B-35R 2kW transducer
is suitable for boats from 5 to 60m and has 40
frequencies. These range from 66 right through to
109 kHz, with selectable low or high frequency for
every range. This transducer enables you to run two
frequencies at once, as well as adjust the Gain and
TVG independently, regardless of the depth. This is
a real game-changer in terms of marine electronics. - Having Frequency Choice and Frequency Adjust in
the sounder menu means it’s very easy to operate.
The beam angles are designed for deep and shallow
waters, and automatically adjust to suit the frequency.
This transducer is a terrific all-rounder that is easily
fitted and supplies tremendous performance. - Alternately, the Furuno 38B-15R is a 3kW transducer
that is 100% dedicated as the ultimate choice for
deep-water and larger boats.
This screenshot from a Furuno FCV295 running a Furuno 82B-35R transducer shows a
green band of micro-organisms like plankton at 300m. The bottom has been expanded with
Marker Zoom on the left-hand side of the split-screen, and shows the pink marking of a
swordfish sitting just above the bottom in 475m.This screenshot from
a Furuno FCV1150
running a Furuno
82B-35R transducer
shows a school of
bait suspended off
the bottom in 480
to 500m. The left
side of the split-
screen view is using
Marker Zoom mode
to expand the main
area of interest. In
the white panel at
top-right above the
screen is an arrow
with a wiggly line,
which means there
is a Furuno Sat
Compass connected
to the sounder. This
compensates for
heave, pitch and roll
so it takes the swell,
wind, current and
tide into account,
providing a much
more accurate depth
for bottom mapping.“The Furuno
FCV1150
and FCV295
models are
an excellent
sounder for
deep-water
work.”
