Bottom Alarm
The Wide One Hundred contains an audible alarm to warn you of shallow water depths. This alarm is adjustable from 2' to 99' of depth. To enable the alarm, simply adjust the alarm depth using the UP and DOWN arrow buttons, and press ENTER. Whenever the depth of the water beneath your boat is equal to or less than the selected alarm depth, a continuous alarm will sound.
To disable the alarm, either move to deeper water, or select the Bottom Alarm menu, and press ENTER to turn the alarm off.
Fish Alarm
The Fish Alarm alerts you to the presence of fish, or other targets not attached to the bottom, in the water beneath your boat. The Fish Alarm has 3 different settings which correspond to the 3 different size fish targets shown
To enable Fish Alarm, use the UP and DOWN arrow buttons to adjust the size return you want to be alerted to; large fish only, large and medium size fish, or all fish. Then press ENTER to enable the alarm. When Fish Alarm is on, an onscreen indicator will be shown.
Remember that it is impossible for sonar to determine if a signal return is a fish or some other type of object or suspended debris. Any object not connected to the bottom is normally a fish and is portrayed as a fish symbol. The strength of the reflected sonar signal from a target is a good indicator of the size of the target, and the fish symbol displayed represents the
strength of the signal reflected from it.
