The Buoy Finder 4A can receive data in the HXV format and in the HVA format. The HXV
format is transmitted by the MkI, MkII and MkIII generations of buoys. The MkIII generation
includes the WR-SG, the DWR-MkIII and the DWR-G. The HVA format is transmitted by the
“4-series” generation of buoys. This includes the DWR4 and the GPS-DWR4.
To change the receiver mode, select the “hxv” or “hva” menu item on the top menu. Press the
