Buying Guide: Key Purchase Considerations
- Coast Guard compliance: Confirm the model meets Coast Guard standards for boats up to 65 feet (20 meters).
- Sound level and range: Choose 118–122 dB for reliable signaling over distance; consider whether you need up to 1 mile of range for fog or crowded waters.
- Can size and weight: Larger cans last longer but may be less practical for small boats; portable mini-horns favor quick access and storage.
- Usage scenario: For larger crews or frequent signaling, a multi-pack offers ready replacements; for solo use, a compact horn is often best.
- Durability and safety design: Look for safety-release features and weather-resistant construction to withstand marine conditions.
