Sonar Menu
Demo Mode
The Demo Mode is a very powerful tool that simulates the fish situation
on the water. Use the Demo Mode to learn how to use your SonarPhone before
go out on the water. All features except Depth Range may be adjusted.
Gain Control
Gain controls the unit's ability to pick up echoes, from 1% to 100%. Current
gain levels are displayed below the digital depth readout as a percentage
of maximum (%). If you want to see more detail, increase the gain a little
at a time. If there is too much clutter on the screen, decrease the gain
to reduce this. Ideally, you want to set the gain to show the strongest
fish echoes with the least amount of clutter. As you change the gain level
setting, you can see the difference it makes on the chart as it scrolls.
When not in the Menu mode, use the large Left and Right arrows on the touch
pad to easily control the gain. If SonarPhone cannot find the depth or the
return signal seems weak on the display, increase the gain level until the
reading is strong.
Usually, a gain level between 30% and 60% will suffice, but increasing the
gain may be required for deeper waters or very soft bottoms. For extreme
shallow water, less than 3 feet, reduce the gain near the minimum setting.
T-BOX ONLY: When using the Wide 40 degree angle, you will need turn up the
gain higher than when using the 20 degree angle. This is normal, as the
cone of sound is covering twice the area.
Auto Depth Range
This setting allows SonarPhone to control the depth range setting for you. It will do it's best to keep the bottom in view at all times,
switching depth ranges as needed. Change this setting to OFF and you can control the range setting manually.
IMPORTANT: While using manual range operation, if the depth is greater than the depth range setting, the bottom will not be visible on
screen. Change the range to a deeper setting or select "Auto" to return to automatic operation.
Depth Range
This setting allows you to manually change the range setting, meaning how deep SonarPhone will read depth. The ranges available are:
0—9 feet, then 10 foot increments deeper to 120 feet (0—3 meters to 0—36 meters)
