CONTROLS AND OPERATIONS
CONTROLS AND OPERATIONS
POWER:Press the PWR/Light, switch on the front panel of the IDF unit to turn the
unit on, a second push will turn the backlight on. Push a third time to turn the
backlight off. A long depression of the PWR/Light switch will power the IDF off.
SENSITIVITY:The logarithmic nature of the Sensitivity Control allows improved
fine tuning of the unit‘s gain. From the zero setting to the 32 setting of the
sensitivity key the gain is increased from zero to full. At the 10 Position the
gain is approximately 20% with full gain being achieved at the 32 setting as
shown on the display.
RANGE:The unit powers up on the 40' RANGE and can be changed to the
80' or 120' RANGES by depressing the RANGE button. The selected RANGE
will be displayed in the center of the IDF. A shallow RANGE selection may not
display a bottom return.
SUPPRESSION:The unit will power up without SUPPRESSION. To add SUPPRESSION,
press the SUPPRESSION key. Pressing the key again will eliminate SUPPRESSION.
S
UPPRESSION
provides an advanced level of control over the amount of visi-
ble detail on the unit. You can choose the setting that works best for your
style of use.
With S
UPPRESSION
set to OFF, the
IDF
displays increased detail, showing more
thermoclines, structure, fish and even your bait when it falls within the sonar
cone. However, this extreme sensitivity requires you to optimize the installation
of your unit and transducer so that “noise” generated by a moving boat is not
picked up by the fishfinder.
With S
UPPRESSION
set to ON, excessive clutter often caused by interference from
other fishfinders, your boat‘s engine, or from noise generated by the hull at
high speeds is reduced in the display. This provides a cleaner image on the dis-
play in most cases. Adjust SENS (S
ENSITIVITY
) for best display at various speeds,
from trolling on up to your boat's maximum speed with RealTime™Sonar.
BACKLIGHT ON: To turn the display BACKLIGHT on press the Power Light
switch once.To Turn the Backlight off, press the Power Backlight Switch momen-
tarily. Continued Depression will turn the Unit off.

SIGNAL INTERPRETATION

SIGNAL INTERPRETATION
Remember, sound waves bounce off a target and return with the strength of
its density. More dense targets (i.e. large fish) return and display a strong sig-
nal. Less dense objects (i.e. weed, schools of small fish) return and display a
weak signal. Dense objects on the edge of the cone return a weaker signal.
This IDF Series unit is extremely
sensitive and powerful. It will
give a very detailed representa-
tion of the environment beneath
the transducer. Information on bot-
tom hardness and content, weeds,
brush, steep slopes and fish are readily
attainable.
The Zero mark will be on at all times.
This mark represents the start of the
Sonar Depth scale, which is relative to
the placement of your transducer.
Sensitivity is adjusted using the SENS - and the
SENS + keys, the present setting adjusted and
shown when either key is depressed

As With all sonar units, experience is the best device for interpreting the target
returns accurately. To aid in the interpretation on the display, the following
examples are provided.
A hard bottom starting at 20' with a
Big fish giving a strong return at 15'.
If a fish moves horizontally through a
sonar cone, it will start at one level,
move up and then back down again
as it moves beneath the transducer.
Hard Bottom: The illustration at the bottom of
the previous page identifies a hard bottom at 18
feet. You can determine a hard bottom because of the strength of the return
(clear, black signal). A second echo would normally appear at 36 feet.
However, the IDF unit has a feature to prevent wrap on all scales to assist in
differentiating bottom, second echo and fish.
Soft Bottom: A soft bottom is displayed on
the IDF as a gray return. Soft bottoms absorb
the sound waves and thus return a weak signal. Adjust the sensitivity level for
a better bottom signal.

Suspended Fish: This display is read-
ing suspended targets at 11' over an
18' bottom.
Fish near the Bottom: The IDF offers a
3.43" target separation. The result is the abil-
ity to identify targets laying on or very close to the
bottom. This illustration shows a fish one segment from a hard bottom. Most
other electronic units would not read this fish since they offer a target separa-
tion of 6" to 12".

Grayscale: The grayscale feature on the IDF will identify the 1) size of a target,
2) presence of baitfish 3) bottom content and 4) fish on the edge of the cone
angle. Here, a fish at 16' is moving either in or out of the transducer cone,
while another fish is directly under the transducer cone near 17'.
Fish at 17' and either baitfish or
larger fish at edge of cone at 16'.
SUPPRESSION
Dead Zone: Any and all sonar devices will have a dead zone in certain
instances, such as sharp drop offs. Anything below the shallowest return in the
cone cannot be seen.
A sloping bottom causes a “Dead Zone”.
In this illustration, the Dead Zone starts
at 20' and continues to 26'

Trees: the signals here indicate an underwater tree or brush pile. The water is
18' deep and the tree extends to 7'. Limbs at various depths return individual
signals. Since fish relate to submerged trees and similar cover, these are excel-
lent areas to fish. To detect fish, anchor your boat and watch for signals that
come and go or move to different depths. Trees, of course, will appear station-
ary. Another way to identify fish is to reduce the sensitivity and grayscale to
minimize the number of segments. Dark segments may be fish.
Structure such as trees give returns at
various depths.
SUPPRESSION
Weeds: Fish also relate to weeds so the ability to identify weeds is very important.
Solid weeds can appear as part of the bottom. If this is the case, use the sensitivity
control to grayscale out the weeds and mark targets holding in the cover.
17' bottom with low dense weeds changing
to sparse weeds at 14', a possible fish at 13'
and clear water from 11' up.
