^• Actual maximum range depends on environmental conditions.
^•• Beam width reported at half power level (-3dB).
^† Side lobe suppression improves the aspect ratio of the instrument enabling greater measurement range in shallower water.
^‡ FS = Full Scale.
^§ Power consumption will be higher is Flow Display is enabled.
