A neighbor had left their gate open, and it was a really frightening situation. Ever since then, I’ve carried this horn as a precaution. This morning, we were out walking when another group of dogs came charging toward us. Thankfully, I was prepared this time. I pressed the horn for just 3–4 seconds and the dogs immediately stopped in their tracks and bolted the other way. It was loud enough to scare them off quickly without me or my dogs getting hurt. What impressed me is that even after using it, I still have plenty left for future use. It’s small, easy to carry, and works exactly as described. If you live in an area where there are stray or aggressive dogs, I highly recommend this as a first line of defense before something serious happens. It gave me peace of mind and kept my dogs safe. Review: This air horn is VERY loud. Wear ear protection. - Invest in a pair of ear plugs because this horn is incredibly loud. Don't use as a prank to scare people as it will damage your hearing. It is compact and light, it's easy to put in your pocket. Made in the USA and meets U.S. COAST GUARD REQUIREMENTS. If you're in need of help, this will get attention. It will probably scare a bear away. You only need a couple short blasts to scream out 120 dbs. That way it can be reused dozens of times. 10 out of 10. ## Features - WHEN YOU NEED TO BE HEARD, 120 DECIBELS CUTS THROUGH EVERYTHING: A whistle gets lost in traffic, wind, and engine noise.

Hope that helps and thank you so much for your interest in Better Boat. **Q: What is the purpose of the screwable cap on the opposite side of the horn for?** A: This is used during production to assemble the portion that makes the noise within the horn. You don't need to open it or adjust anything with it. Hope that helps and thanks so much for your interest in our Air Horn. It means a lot to us here at Better Boat. **Q: Is there an expiration date? How long does the air last before you have to buy another one?** A: Not a date on the container. This thing was basically worthless. Blasts intermittently, most of the time does not work. Save your money do not buy this thing. I give it a zero rating. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Life saver for me and my dogs *by X***S on October 3, 2025* I originally purchased this air horn back in March after my dogs and I were attacked by four loose dogs in the neighborhood.

Maybe You Shouldn’t Be Here *by R***S on December 7, 2025* If you’re looking for a discreet buzzer for middle-school sports games, this little can from Better Boat is absolutely not—it’s basically a sonic rocket launcher with a “go home or go deaf” option. The blast is powerful enough to carry half a mile and hits roughly 115 dB. When I first fired this off, teammates flinched. Nearby parents turned their heads. The ref might’ve flagged me for excessive celebration. But if your goal is to command attention—be it start of game, end of quarter, or that one kid who forgot his cleats—this thing delivers: loud, sharp, and impossible to ignore. I can’t guarantee your eardrums will forgive you afterward. But the kid who gets up the next morning with a ringing in their ears might at least remember who scored the last touchdown. ## Frequently Bought Together - Marine Safety Air Horn, Very Loud Handheld Fog Horn, Large Compressed Can 3.5oz for Boating and Walking Safety - Kidde Mariner PWC Marine Fire Extinguisher for Boats, 5-B:C, 3.3 Lbs., Coast Guard Approved, Mounting Bracket (Included), White - Seachoice Emergency Marine Foam Flotation Cushion, Square, 15 in.
