About Train Horns for Hercules® 20v Battery
Train Horns for Hercules® 20v Battery — Strength Meets Sound
The Hercules® series is designed for those who demand maximum durability and legendary power in a portable train horn. Built from brand-new impact drivers and fitted with heavy-duty metal trumpets, these horns live up to the Hercules® name—strong, bold, and ready to roar.
Unstoppable Performance
- 150 dB+ of chest-pounding sound
- Wireless Remote Control: 160 ft standard, up to 2,000 ft with our long-range upgrade
- Durable Build: powder-coated trumpets withstand heavy use and tough conditions
- All-Day Power: efficient compressor runs long on a single battery charge
Choose Your Hercules® Setup
- Dual Trumpets: compact yet powerful, ideal for portable use
- Quad Trumpets: fuller, deeper resonance that demands attention
- Extreme Series Quad: the ultimate Hercules® blast, engineered for the loudest possible impact
Why Hercules® Stands Out
- Ready to Use: pre-assembled from a brand-new drill—just secure your battery
- Handheld Power: designed for portability (not for under-hood installation)
- Water-resistant: built to handle the outdoors, though not fully waterproof
- 1-Year Warranty: peace of mind on every Train Horn for Hercules® 20v Battery
