1.18 Deep Gain
“Deep Gain” compensates for propagation
attenuation of the ultrasonic waves. It does
this by equalizing echo presentation so that
fish schools of the same size appear in the
same density in both shallow and deep
waters. In addition, it reduces surface
noise.
1. Press the [MENU/ESC] key to open the
menu.
2. Use ▲ or ▼ to choose DEEP GAIN
from page 1 of the menu.
3. Press ► to show to the options window.
4. Choose Low, Medium, or High as
appropriate. High provides the greatest
degree of gain reduction against short
range echoes.
5. Press the [MENU/ESC] key to close the
menu.
