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.

This is a good/cheap replacement for the broken horn on our boat. It allows us to meet the requirements for a signaling device. It takes up space in the glovebox but never needs a refill & works every time.Do NOT show a 5 year old how to use it. You will never get any peace after. It is very loud. More so than the original electric horn on the boat.

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.

I was looking for a replacement for my old handheld Stowmaster fog horn that has been discontinued. This horn looked interesting. It was larger than I expected but is, indeed loud. For kayaking use, I might try to saw a couple of inches off the bell to make it a little more compact. I've included a photo of it in my hand for scale.

Solidly made (in the USA) and as advertised: the thing takes very little breath to be LOUD, I mean, as in, my ears are ringing loud (don't try this in an enclosed area or in someone's ear). Diaphragm is apparently easily replaced with some plastic film if it gives up the ghost. Seriously, for a small boater or to frighten off critters, this thing fills the ticket. A bit large to carry on your person for emergencies as everyday wear, but easily clippable to a backpack for bear duty.The only drawback I see is it does look a bit like a bong.Would buy again.

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.

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.
