Tides Tab
The Tides window allows you to change the way the WMB-X230 uses tide information. Assuming the
Disable Tides check box is cleared, the WASSP system uses the GPS positioning information coming
through the WASSP Processor communications port to automatically select the closest tide station.
The WASSP system then calculates a tide offset value and adjusts the seafloor profile data using the
tide offset value.
Selecting the Disable Tides check box can cause the seafloor depth to vary as the tide waxes and
wanes, resulting in inconsistencies in seafloor mapping. Disable Tides should be selected if you are
working on a lake.
Enter the local time difference in hours (from Coordinated Universal Time UTC) into the Local Time
difference field to update the Current Time and Next Tide times to local time.
