Manual Mode - Lowrance HDS-8 Operation Manual

To adjust Surface Clarity:
1. Select Surface Clarity from the Sonar Settings menu and press
enTeR.
2. Use the keypad to choose the desired option.
Scroll Speed
Controls how fast the sonar chart scrolls across the screen. A slower scroll speed
is best suited for ice fishing or fishing while
at anchor. It is also useful when you want
to record a higher quality sonar log in deep
water. By default, Scroll Speed is set to
normal.
To make adjustments, select Scroll Speed from the Sonar Settings menu and use the
keypad to make adjustments.

Manual Mode

Advanced user mode that bypasses digital depth to give you greater control of ping
settings. Digital depth causes the unit to search for the bottom regardless of the
portion of the water column you are targeting. While you still will get good results
using digital depth, it prevents you from getting optimum performance in certain
situations, like fishing for suspended targets.
In Manual Mode the unit sends sonar signals (pings) only to the depth range you
select. Adjustments made to the range setting will be reflected in your unit's ping
speed. That makes it easy to get the best scrolling speed and the best screen resolution
for a selected range.
Select Manual Mode from the Sonar Settings menu and press enTeR to turn on/
off Manual Mode.
