The T-H Marine HydroWave Mini Bass Edition gives bass anglers a compact sound system that helps pull fish into range and trigger more aggressive feeding when the bite gets tough. Built for bass fishing from a kayak, jonboat, or even the bank, this portable unit uses Passive and Frenzy sound modes, an amplification system, and lateral and vertical reaction technology to add another edge when you are working jigs, moving baits, soft plastics, or topwaters around grass, docks, wood, and offshore structure. Waterproof and shock-resistant construction helps it handle real time on the water, while the controls at the head let you adjust volume and play or pause sounds quickly without breaking your rhythm. Powered by one 9-Volt battery, sold separately, the HydroWave Mini Bass Edition runs about 6 to 8 hours on a single battery, making it a practical tool for mobile bass anglers who want fish-attracting sound in a smaller package.
