Attwood 2460-7 Bellow Signal Horn, Lung-Powered, Meets USCG Rule 33 (Annex III) and EPA Regulations, 8 Inches H x 3 ½ Inches W

After learning about the existence of these human-powered, kazoo-like horns I bought three different kinds. From high to low price: the "Attwood Bellow Signal Horn", the "SeaSense Safety Blaster Horn", and the "Coghlan's Emergency Survival Horn".All allow you to simply blow to make a loud, kazoo-like sound.All allow you to replace the vibrating membrane with any thin sheet of plastic (such as plastic wrap).All are made of hard plastic and should be impervious to water damage, although the Coughland is made of a cheaper, more brittle plastic, while the SeaSense is of a more robust plastic, with the Atwood in between.In loudness, the Coughland was the softest, while the SeaSense and Atwood seemed equally very loud. It was easy with the Atwood to blow softer or harder to make the sound quieter or louder -- not so easy with the others.In pitch, the Coughland was the lowest, the Atwood in the middle and the SeaSense was the highest. Uniquely, the SeaSense can easily be configured to produce three different pitches -- which might make a difference depending upon the context (e.g. on open water vs in a forest or in a mountain valley).In size, the Coughland and SeaSense were about equal and could if needed fit into most pockets, the Atwood was two to three times as large.In price, the Atwood was three times the price of the other two. On the other hand this is the only one where it should be obvious to anyone who picks it up where to blow into it.The Coughland and SeaSense both emit sound to the left and right (near your ears). Cupping your hands behind the left & right ends shield your ears a little from the loudness. The Atwood emits sound forward and away from you, which helps a little. All of them will be loud to your ears no matter what you do.

The media could not be loaded.  If you’re going to an event and want to make a loud noise without using an compressed gas airhorn, this is your item. This manual air horn requires little effort when blowing into the tube (check out my vid) and increases in loudness the harder your blow. This airhorn is a little bit clunky in comparison to other airhorns I bought on Amazon, but definitely the most user friendly.

I purchased a returned one for half the cost. I blew in it and it didn't work. Couldn't figure out how to open the bottom and was afraid to break it. Got on Amazon and went to the Q&A section and read the answer to another person who couldn't get theirs to work. Tried to open it again and finally managed to pull the bottom off. Cut a piece of plastic off the bag it came in and tried to put it inside the bottom lid. Put it together and again it didn't work. Took it apart and tried saran wrap... nothing. Must have taken it apart and tried again at least half a dozen times. Just as I was ready to give up and start the return process, I re-read one of the answers and noticed it said to stretch the plastic wrap. Well there's no way to stretch the plastic wrap inside the lid, so I stretched it across the bottom of the air horn and put the lid on. That did the trick! I texted my landlord who lives on the property and asked him to tell me how loud it was. He said it sounds like a lost calf. Asked if he thought it would scare an assailant away. He said "while they are doubled over from laughing you can run away🤣". LOL. Maybe it'll scare loose aggressive dogs away.

I was a little apprehensive about a signal horn that you blow into being loud enough to be heard over a long distance. Much to my surprise it worked very good. It is very loud and works really good. I tried it out in my neighborhood when it arrived and it started the dogs barking for miles from my house. It is very loud and at a pitch that it can be heard from quite a distance. I like it a lot better than the canned air horn on my boat and I don't have to keep buying the cans to keep the air horn working. I would recommend it to anyone looking for an alterative horn when you want to be heard from a great distance. Also surprising is that you don't have to blow into it very hard to make it work. Great little horn, it would also be a great horn for football games or other outdoor sports events where you want to be heard when rooting for your team. A note of caution: don't blow it when your close to someone's ears.

WHEN it works, it works fine. It basically sounds like a bleating billygoat. 103dB at ~1ydThe problem is that it is stupid construction made with cheap plastic parts that break easily. Even if you test it and carefully set it aside in a kid glove padded box, when you pull it out to alert the incoming ship of your presence, it may very well not work, and SPLAT! You’re dead!When the plastic “reed“ inevitably breaks, replacing it requires several minutes of fidgeting and adjusting. “When seconds count, it’ll be ready in just a few minutes!”USCG should never have approved this piece of junk!Do NOT depend upon this on any boat ever.

This signal horn requires a large volume of air and makes a poor screeching high pitch tone. Not a good choice for sporting events. I had hoped for a low tone boat horn sound…..not this.

I have an issue with the local black bears getting into the neighboring half-way house's garbage and bringing the bags into my yard for their garbage picnics. If I hear the cans being raided in the daytime, I can step out onto my front porch and give a toot or two on this. The bears look at me, pretty obviously can't figure out what I am since no animal makes _that_ noise, and return to the woods. I seem to have stopped them coming into my yard, between this, solar motion-sensing lights, and a Critter Ridder motion-sensing sprinkler. Works, where talking to the house managers does no good because they're replaced often. Lot of trouble to be put to by inconsiderate neighbors, but....

Bought this as a fan noisemaker for sports. It works exactly as advertised. Too loud too use Inside the house even to test. Hurts my own ears if I use it extensively at games. Annoys the hell out of the opposing team's fans. It's perfect.

Needed to replace the plastic film it came with. And after a bit of trial and error found that the plastic cover on processed cheese slices works great!

Parfait pour faire du bruit dans un arena et sur un terrain de football

We bought this to use as a bear deterrent while hiking. It's genius. It's loud, fits into any holder that you'd have for a water bottle. Literal perfection.

Great for games keep in classic Antique car. nice noise maker
