The T-H Marine HydroWave Mini Mr. Crappie Edition gives crappie anglers a compact sound system that helps pull fish closer and trigger more active feeding around brush piles, docks, timber, and open-water schools. Tuned for crappie fishing, this portable unit features Passive and Frenzy sounds along with an amplification system and lateral and vertical reaction technology that add another layer to your presentation when you are shooting docks, working minnows, or hovering over suspended fish. Waterproof and shock-resistant construction helps it handle real-time on the water, while simple controls at the head let you adjust volume and play or pause sounds without slowing down. Powered by one 9-Volt battery, sold separately, the HydroWave Mini Mr. Crappie Edition runs about 6 to 8 hours on a single battery, making it a practical tool for crappie anglers who fish from boats, docks, or tight mobile setups.Tuned specifically for crappie fishing with Passive and Frenzy sound patternsAmplification system with lateral and vertical reaction technology adds fish-attracting soundWaterproof and shock-resistant construction holds up in everyday fishing conditionsHead-mounted controls let you adjust volume and play or pause sounds easilyEquipped with:Mr. Crappie HydroWave MiniWaterproof speaker with 8 ft. cordUser guideWarranty cardManufacturer's warranty Made in the USA
