14.3 Fishfinder presets
The fishfinder provides you with four preset configurations available
from the fishfinder menu. These enable you to quickly select
appropriate settings tailored for various situations.
Each preset has been configured to provide the best operating
parameters for the fishfinder. However, it is possible to manually
adjust the presets if necessary. The four default presets are:
• Single — this preset provides quick access to a single-frequency
configuration, suitable for general fishing conditions.
• Dual — this preset provides a dual frequency configuration.
You can either display two different frequencies at the same
time in one window, or display one frequency at full-screen on
your master display and the other frequency at full-screen on an
additional networked display.
• Shallow — this preset optimizes the fishfinder display for shallow
waters.
• Deep — this preset optimizes the fishfinder display for deep
waters.
