This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant
to Part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates, uses and can radiate radio frequency
energy and, if not installed and used in accordance with the instructions, may cause harmful interference
to radio communications. However, there is no guarantee that the interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or television reception, which can
be determined by turning the equipment o and on, the user is encouraged to try to correct the interfer­ence by one or more of the following measures:

• Reorient or relocate the receiving antenna

• Increase the separation between the equipment and receiver

Sonar operation | HOOK X series

CHIRP

A CHIRP (Compressed High Intensity Radar Pulse)
transducer transmits a modulated pulse of all
frequencies within the bandwidth of the selected
transducer type.

This results in better image quality, better target
separation and greater depth penetration.

This unit supports High CHIRP, Medium CHIRP
and Low CHIRP, depending on the transducer.

CHIRP can be used with Lowrance conventional
sonar transducers.

• 50/200 kHz (Low/High CHIRP)

• 83/200 kHz (Medium/High CHIRP)

To use CHIRP, select the desired CHIRP frequency
from the Frequency menu.

This unit supports two types of sonar: Conventional
and DownScan.

The features described in this section are for
conventional sonar. Refer to the DownScan
operation section for information on DownScan
features.

Sonar operation | HOOK X series

Sensitivity

Controls the level of detail shown on the display.
Too much detail will clutter the screen. If Sensi­tivity is set too low, desired echoes may not be
displayed.

Colorline

Helps distinguish sh or structure from the
bottom by showing hard returns as light colors
and soft returns as darker colors. A lower colorline
setting will display only the hardest returns,
shown in light colors.

Auto sensitivity

Keeps sensitivity at a level that works well under
most conditions, reducing the needs for adjust­ments. Auto Sensitivity is turned on by default.

NOTE: You can make minor (+/-40%)
changes to sensitivity with Auto
Sensitivity turned on. You will have to turn
it o to make signicant adjustments.

Range

Selects the deepest range shown on
the display. Range settings display
the section of the water column from
the water surface to the selected
depth range.

If you select too shallow a depth range, the unit
will not be able to lock onto the bottom.

Custom range — Upper and Lower limits

Used to select the upper limit and lower limit of
a section of the water column. That allows you to
view a section of the water column that does not
include the water surface or the bottom. Upper
and lower limits must be at least 6.5 ft (2 m) apart.

Frequency

Controls the transducer frequency used by the
unit. This unit supports conventional, CHIRP and
DownScan sonar frequencies.

Only frequencies supported by
your transducer will appear on the
Frequency menu.

Custom range menu

NOTE: When using a custom range,

you may not receive any digital depth
readings, or you may receive incorrect

depth information.

Sonar frequencies

50 kHz

Best depth penetration with
lower resolution

83 kHz

Wider cone angle provides more
bottom coverage and easy lure
tracking

200 kHz

Highest sensitivity and best tar­get separation in shallow water

Low CHIRP

Provides the best depth pene­tration with lower resolution

Medium
CHIRP

Better depth penetration than
High CHIRP with minimal loss of
target separation

High CHIRP

Better resolution in shallow
water than Medium CHIRP

Custom high

Selects a custom single
frequency from within High or
Low frequency ranges to help
reduce/eliminate interference
from other CHIRP transducers

Custom

19

Sonar operation | HOOK X series

Ping speed

Controls the rate the transducer uses to send so­nar waves into the water. Ping speed adjustments
can help reduce interference from other trans­ducers. When using shing modes, ping speed
settings are optimized for the selected shing
conditions, so in most cases, adjustments are not
necessary.

Sonar options

Noise rejection

Uses advanced signal processing to monitor the
eects noise (boat pumps, water conditions,
engine ignition systems, etc.) has on your display,
and then lters out undesired signals.

20

Sonar operation | HOOK X series

Amplitude scope

Displays the amplitude of the
most recent echo.

Fish ID

Displays sh echoes as sh sym­bols instead of sh arches.

NOTE: Fish ID is not the most accurate

method of sh detection since structure
and suspended debris may be shown as
a sh symbol on the display.

DownScan options

You can make adjustments to DownScan overlay
settings from the sonar page. DownScan options
are covered in more detail in the DownScan
operation section.

Surface Clarity reduces
surface clutter by

You can adjust settings for both Conventional
sonar and DownScan sonar modes from the Sonar
Settings menu.

Only adjustments made to conventional sonar
settings will be visible on the sonar page.

WARNING: Manual mode should only

be used by advanced sonar users.

Manual mode

Restricts digital depth capability, so the unit will
only send sonar signals to the selected depth
range. That allows the display to continue smooth
scrolling if the bottom depth is out of transducer
range.

unit by providing preset packages
of sonar settings geared to specic
shing conditions. For more
information about shing modes,
refer to the Basic Operation section.

Reset shing mode

Resets selected shing mode to default settings.
That is useful when you want to clear settings
adjustments made while using a shing mode.

Installation

Keel offset

All transducers measure water depth from the
transducer to the bottom. As a result, water depth
readings do not account for the distance from
the transducer to the keel/bottom of motor or
from the transducer to the water surface. Before
setting keel oset, measure the distance from
the transducer to the bottom of the motor - see
illustration next page.

Installation menu

Temperature calibration

Calibrates data from the transducer temperature
sensor with data from a known temperature source
