Adjusting The Radar Image - Lowrance HDS PRO Operator's Manual

The cursor assist function
The cursor assist function allows for fine tuning and precision
placement of the cursor without covering details with your finger.
Activate the cursor on the panel, then press and hold your finger on
the screen to switch the cursor symbol to a selection circle,
appearing above your finger.
Without removing your finger from the screen, drag the selection
circle to the desired position.
When you remove your finger from the screen the cursor reverts to
normal cursor operation.
Go to cursor
You can navigate to a selected position on the image by positioning
the cursor on the panel, and then using the go to cursor menu
option.
New waypoint
You can save a new waypoint at a selected position by positioning
the cursor on the panel, and then using the new waypoint menu
option.

Adjusting the radar image

The radar image can be improved by adjusting the gain, by filtering
out unwanted echoes due to sea clutter, rain or other weather
conditions, and by tuning the sensitivity of the radar receiver.
You can adjust the gain, sea clutter, and rain clutter from the radar
panel main menu.
Ú Note:
The radar image settings do not affect the AIS targets.
Sea and rain clutter can be present at the same time, and further
degradation in detection performance will be experienced. As sea
clutter is related to short range and rain clutter is usually present in a
longer range, rain clutter settings can be adjusted without affecting
the echoes in the sea clutter area.
The radar image can be adjusted as described in the next sections.
