Abstract:

An underwater depth discrepancy system and method are provided. A comparator compares an actual underwater depth with a predetermined prerecorded chart depth corresponding to a current location corresponding to the location of the actual underwater depth. A first signal is generated when the actual underwater depth is greater than the chart depth while a second signal is generated when the actual underwater depth is less than the chart depth. The current location and actual underwater depth are recorded whenever the first or second signal is generated. In addition, one or more alarms are generated when the second signal is generated.
