Advanced Sonar Settings; Transducer Installation Settings - Garmin ECHOMAP UHD2 Owner's Manual

Advanced Sonar Settings

NOTE: Not all options and settings apply to all views and transducers.
From a sonar view, select Menu > Sonar Setup > Advanced.
Interference: Adjusts the sensitivity to reduce the effects of interference from nearby sources of noise.
The lowest interference setting that achieves the desired improvement should be used to remove
interference from the screen. Correcting installation issues that cause noise is the best way to eliminate
interference.
Surface Noise: Hides surface noise to help reduce clutter. Wider beam widths (lower frequencies) can show
more targets, but can generate more surface noise.
Color Gain: See (Adjusting the Level of Detail,
TVG: Adjusts the appearance of returns to compensate for weakened sonar signals in deeper water, and
reduces the appearance of noise near the surface. When the value of this setting is increased, the colors
associated with low-level noise and fish targets appear more consistent through various water depths. This
setting also reduces the noise near the surface of the water.
Bottom Search Limit: Limits the search for the bottom to the depth selected when the Range setting is set
to Auto. To minimize the length of time it takes to find the bottom, you can select a depth to limit the
search for the bottom. The device will not search for the bottom deeper than the selected depth. Adjusts
the appearance of returns to compensate for weakened sonar signals in deeper water, and reduces the
appearance of noise near the surface. When the value of this setting is increased, the colors associated
with low-level noise and fish targets appear more consistent through various water depths. This setting also
reduces the noise near the surface of the water.

Transducer Installation Settings

NOTE: Not all options and settings apply to all models and transducers.
From a sonar view, select Menu > Sonar Setup > Installation.
Restore Sonar Defaults: Restores the factory default settings for the sonar view.
Transducer Type: Allows you to select the type of transducer that is connected to the device.
Flip Left/Right: Changes the orientation of the SideVü sonar view when the transducer is installed backward.
Flipped: Sets the orientation of the Panoptix sonar view when the transducer is installed with the cables pointing
toward the port side of the boat.
Beam Width: Sets the width of the Panoptix transducer beam.
Narrow beam widths allow you to see deeper and farther. Wider beam widths allow you to see more coverage
area.
Use AHRS: Allows the internal attitude heading and reference system (AHRS) sensors to detect the installation
angle of the Panoptix transducer. When this setting is turned off, it is assumed the transducer is installed at a
45-degree angle.
