SpotlightScan | Operation Manual
SpotlightScan Sonar shows structure and fish targets ahead and
around the boat without disturbing these areas before you have a
chance to fish them.
The SpotlightScan transducer can be used for SpotlightScan
imaging, Downscan imaging or as a conventional broadband
transducer.
¼Note: Screen captures shown in this manual were taken on a HDS
Gen2 Touch.
SpotlightScan comes with a trolling motor position sensor that
ensures SpotlightScan returns match up correctly with the
orientation of your boat.
The SpotlightScan transducer can be used with any MotorGuide
or Minn Kota cable-steer trolling motor. Its scanning speed is
controlled by the amount of pressure placed on the trolling motor
foot pedal.
¼Note: Rotate the trolling motor at a slow, constant speed to achieve
the best results.
¼Note: Experienced trolling motor users will achieve better results
with the SpotlightScan system.

Displaying SpotlightScan view
SpotlightScan images are viewed on the Structure
page. You can set up combo pages to view
SpotlightScan images and broadband sonar and/or
Downscan imaging at the same time. You will not
be able to view SpotlightScan and SideScan at the
same time.
1. Access the Structure page
2. Select View
3. Select Spotlight
SpotlightScan image alignment
You must align the SpotlightScan transducer image with the
direction the trolling motor is pointing.
If the SpotlightScan image is not correctly aligned with the trolling
motor, the orientation of the image will not match the underwater
environment around your boat.
1. Position your trolling motor so it is pointing straight ahead
2. Access the Advanced menu
3. Select Position adjustment
4. Move the Position adjustment scroll bar so the top of the “V” is centered at
the top of the display.
¼Note: The “V” on the Structure display represents the beams of the
SpotlightScan transducer. The wide end of the “V” should be aligned
in the direction the trolling motor is pointing.
¼Note: Do not use the arrow indicator on the trolling motor head as a
heading reference as it may not be aligned correctly with the trolling
motor.

Range
You can control how much of the area around your boat appears on
the display by increasing or decreasing the range.
Frequency
SpotlightScan can be used at 800kHz or 455 kHz. 800kHz provides
the highest resolution with less range. 455kHz has the best range,
but with lower resolution.
SpotlightScan operation tips
• Remove slack in the trolling motor cable to prevent image distortion.
• Rotate the trolling motor at a slow, constant speed to achieve the
best results.
• Auto range adjusts the range with the water depth to maximize the
viewing area. This is best when searching for structure.
• Auto range will clear/redraw the image as the range changes. Use a
manual range to maintain a constant image.
• Reducing the range will increase the size of the water column,
providing the best view of fish activity beneath the boat.
