Shoreline Marine Eco Air Horn

Well, this is loud! I bought the smallest one on Amazon, since it's just for emergencies or rarely to get people's attention. (I don't have a boat, or I'd probably have bought a much bigger one.). I bought one as a desert tour guide for stragglers. I warned them "one blast, stop dawdling and walk toward the bus; two blasts, we're about to leave, so maybe you should pick up the pace; three blasts, call an Uber if you can get a signal. We're leaving without you." I never had to use the horn, but just telling them about it made a difference. Especially the part about "call an Uber *if* you can get a signal," something people take for granted in the cities and suburbs, but when you're in the desert mountains, signals are few and far between. The other one I bought a few years earlier for a tenant who had a young, rambunctious upstairs neighbor who practiced nightly noisy interactions of just the type you are imagining. Banging on the ceiling with a broom stick didn't work. Talking to her didn't work (the tenant talking). I finally wrote a letter saying "You know, Mary can hear *everything* you do in your bedroom. Everything." The tenant didn't care, so I bought Mary an airhorn to use to scare the bejeezus out of the rambunctious upstairs tenant. She used it only once, and the tenant upstairs got quieter after that. Long stories, just to show that these things are loud, compact, convenient, and inexpensive. I've never used one long enough to see how long the charge lasts, but for my purposes they were great.

Make some noise

Astounded by the quotes I was given for removing 2 or more raccoons from the attic crawl space of my one story house, I searched the internet for a cheaper alternative that would be safe for me and nonlethal to the little bandits. Loud noise was recommended and seemed like a good bet. This little can full of shrieks arrived within 48 hours and just 3 short bursts of screaming horror did the trick! I stood on the lid of the commode with my ears protected by noise canceling headphones and pressed the button while holding the horn up against the bathroom fan that vents into the crawl space. As I removed the headphones I heard some truly frantic squealing and scrambling in the crawl space. I'd recruited a friend to stand in the back yard watching the torn soffit vent where the critters had gained access and as I dashed out the back door I saw him snort-laughing so hard he'd bent over and was clutching his ribs. Between snorts he said just seconds after the 3rd blast of sound first one and then another FAT and quite obviously terrified raccoons had dropped from the soffit vent and bounded up the back yard slope so fast they'd moved in a blur as if the devil himself was chasing them! We quickly installed a sturdier soffit vent and then rewarded ourselves with a couple of tall, cold ones. Problem easily solved for less than $20 vs $175-$300!

UPDATE: I've now been using the *first* one (of five) for almost four weeks, off and on -- probably, a total of 15+ short (< 1 sec.) blasts. It still feels like the can has maybe 40% or life left; it certainly doesn't get cold when using it, which seems to be the clue that the gas is almost gone. Yes, the horn tends to loosen with use, and the loudness suffers. It needs to be pretty tight to work. I suppose one could put a little Loctite on the threads before the first use, but I just tighten the horn every time I go out. For the price and ease of carrying, I will *definitely* buy these again. ________ I've seen reviews of this device and others that say, "It worked a couple of times, then stopped. Won't buy it again." Here's my take. This is a small, very portable alarm (fits in a pants pocket) that makes a loud noise to notify others that you are either in distress, or want them to stay clear. I'm using them to train my dogs -- definitely gets their attention! The output is VERY loud -- I wouldn't recommend using it indoors -- and I've used it for 5-6 short blasts (1/2 sec. or less), with no obvious signs that I'm about to run out of gas; I expect to get at least 2x that use out of each can. Will it signal the period ends at soccer games over a playoff weekend? Probably not. There are three sizes of these devices, trading off ease of carry vs. the number/length of blasts in the air can. This one is designed to be portable, with enough 'toot' to save one fog-stranded kayak paddler, keep a couple of dogs from chasing squirrels in a park for a few days; or scare away one bear or coyote. For larger jobs, get the 8oz. model, which has 6-7x the compressed air. And I don't know if they've improved the design, but my horns have brass thread where they attach to the canister, so if tightened properly, they shouldn't leak air. If I had any complaints, it would be that the button on the horn is kind of hard to push: it's not possible to give a polite 'chirp' -- when pressed, one has to mean to use it!

I love it because bears hate it.

It worked OK however I prefer the smaller ones better. I use these to call my Australian shepherd back when he gets out of sight. The smaller ones have a different pitch

This is the 4th one I have ordered and it leaks badly. I was careful attaching the horn to it and have repeatedly tightened it to stop the leaking but can't get it to stop. Since the others worked fine I think this one is faulty. I ordered it, as a defense against bears which seem to be in an abundance this year so it was important to me that this worked !!!

"The first blast was loud enough. The second blast sounded exactly like a big fart, and the airhorn stopped working! I believe it was a message from the company that **you deserve a fart** because you trusted their product."

Defective trigger….when using a white gas was release and burnt my finger and thumb

Was tinier than I envisioned, so wasn't expecting it to be as loud as I needed. Tested it out real quick on the deck with a short burst and nearly blew my eardrums out.

Well the size was smaller than expected but the product worked out.

This product provided the functionality that was claimed. However it is a dangerous device that has not been properly labeled. The United States Centers for Disease Control indicate that ‘noise above 120 dB can cause immediate harm to your ears’. This horn delivers 120 decibels. A quarter second button press and my ears were instantly in pain and ringing. Not indicating the danger clearly on the product would be as irresponsible as not labeling a hazardous chemical. Make sure children do not have access to this horn, and ensure that you protect your ears before use. Also, note that the sound of the horn is very high frequency, similar to the high piercing sound a balloon makes when air is released through a flattened valve (so, not like a low fog horn).
