Waterproof. Rugged. Durable.

Built to defy the severe environmental elements that commonly ruin other megaphones: corrosion, cracking, breaking, water damage. The strong and durable polycarbonate material enables the megaphone to withstand nature even on its toughest days in order to prevent cracks and corrosion over time. The ergonomic, wrap-around handles provide an easy and comfortable grip for the user. This rugged, handheld megaphone is IP67 water resistant, fully submersible, floats to the surface, and meets MIL-STD-810 Transit Shock Standards. The rechargeable Lithium Ion battery pack provides up to 8 hrs of use, and the Charging Station is included.

Customer Reviews

Hear what our current customers are saying about the Blue Ocean Megaphone.

Finally made a product that can withstand a rowing coach's level of punishment.

"Over the course of the last three years I've probably gone through 6-7 megaphones (plastic and electric). Lost at sea, dropped or soaked in the rain. For one of the most important tools that we use on a daily basis, that can be incredibly frustrating. I'm very grateful you've finally made a product that can withstand a rowing coach's level of punishment."
—Scott W.

It is the best product on the market.

"I have found the Blue Ocean much clearer and louder than the Fanons that I had used for many years. Our rowers have all commented on how they prefer to hear me with the Blue Ocean. It is lighter than comparable products. I use the Blue Ocean confidently in all weather conditions. It continues to work in the rain and it will work again the next day. There doesn't seem to be a drying out period, the way others have had. Being able to use it in all conditions is definitely one of its big pluses. I have now bought eight Blue Oceans for our program and recommend it to every coach I meet. It is the best product on the market."
—Andy A.

Rain damage and dead-batteries are issues from the past.

"The Blue Ocean is well worth the money and indeed saves battery and parts-repair directly. The recharge is at least 2-3 full days use over long-range. Recharge is very quick. Rain damage and dead batteries are issues from the past. The horn and siren volumes are a great new benefit also."
—Ted N

Saving time with clearer communication.

"I wish to express my appreciation on the quality of Blue Ocean Megaphone. I had no idea how antiquated our older system was until it finally failed and was replaced by your product. It is light, reliable in all weather conditions and the battery life is outstanding. The most important impact is the saving of time. I no longer have to repeat directions due to distortion. An unintended benefit is that my "pit" personnel, over 600 yards from my firing line, can hear the commands and anticipate what my needs will be before I call them on a radio. Often times, they were ready for an event based on hearing the commands over the Blue Ocean Megaphone 1/2 mile away. Saving a few minutes over the course of a week on 10 events times 60 shooters added up to hours of time saved! This is a great addition to our competition."
—Daniel W.
