"The HydroWave KVD H2 is a Marine Audio Device based on the reactive senses of a Bass and other predatory fish. The HydroWave H2 delivers the latest in patented, sound emitting technology, effectively imitating the audible underwater sounds of baitfish and fish-feeding activities. Research has proven these sounds stimulate feeding in game fish. In addition to the 16 sound patterns on the H2 Bass HydroWave, the KVD H2 has 9 additional sound patterns designed by Kevin VanDam for specific fishing situations:

• Shallow Power • Shallow Finesse • Vegetation • Top Water Schooling • Off Shore Structure • Off Shore Schooling • Off Shore Finesse • Marinas/Docks • Crawfish"
