Maximum depth for the bottom detection algorithm. The
default value depends on the transducer installed. A
depth setting of 0 m disables the bottom detection
algorithm. See Minimum Depth description above.
0.0 to 4,999.9 m in steps of 0.1 m
Alarm when detected depth is shallower than depth
setting. A depth setting of 0.0 meter disables the alarm.
0 to 5,000 m in steps of 1 m.
Alarm when detected depth exceeds depth setting. A
depth setting of 0 meter disables the alarm.
