The Blue Ocean is the world’s most rugged megaphone, built to defy water damage, sinking, corrosion, cracking, and splitting. Use for up to a full day on a single charge, or bring an extra rechargeable battery for peace of mind.
The Blue Ocean Megaphone is the the latest product developed by Nielsen Kellerman, the manufacturer of all Kestrel weather meters. Designed originally for the rowing industry, these megaphones have become extremely popular with military, fire and police departments, and others who need to be heard by a large group of people.
The Blue Ocean is the most durable, weather resistant bullhorn you will find. It was uniquely designed and carefully built to defy severe weather that commonly ruin other megaphones; corrosion, cracking, breaking, and water damage. This megaphone is waterproof, and actually floats if accidentally dropped in the water. The two handles on the Blue Ocean increases the durability, as well as make it easier to handle than the typical megaphone.
