Shoreline MarineEco Air Horn

This is useful to blare as personal protection. Police in Florida advised me . I had to use one there as in my gated yacht community a person was stealing my $50 solar light and I told Him to put it down. He came at me and I blasted him ! He ran like HELL

I keep this in my glovebox in case of emergency.

LOUD.

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 used it for a prank on Rae Love and it was soooo LOUD. Didn't put it anywhere near my or anyone's ear. Do not use in a small space. It's loud.

This is really a life saving product.Plus it's a great way to scare off unwanted animals from the gardens and yard.

Finally got around to trying this little horn. The sound is great. The problem is the thing leaks all over your hand. Very cold and not good for your hand.

It only lasted two days that was very disappointing but I got to say it's really loud and my friends keep pressing the air horn button at school lol if it wouldn't have broken 2 days I would have gave it five stars but it's at 3 sorry
