HEIMDALL Emergency Whistle with Lanyard for Safety Boating Camping Hiking Hunting Survival Rescue Signaling

They are just what I was looking for. Got this for my runs, not sure what good they’ll do but I feel better having something extra in case I need it (to draw attention). I like how they also have a place to clip the whistle to a shirt, shorts or belt if you wanted to. They’re loud & well made

I read a product review stating that these whistles aren’t very loud, and when I received the product I was inclined to agree. When i blew on the whistle it was very soft, almost muffled. However when my son (whom i bought it for, to wear on his life jacket) blew it, it was plenty loud. There is a slight trick to get the loud sound. For most whistles you would purse your lips and put them as close to the end of the whistle as possible, being careful not to get too close to the air hole at the top. Not so with these whistles! To get the loudest sound, you actually need to put your lips as close as possible to the air hole without covering it. I think that is why this is a great whistle for my 6 and 7 year old sailors. They don’t have the finesse to be careful where to put their lips. They just clamp on and blow and it works perfect. And the price is right with two whistles in the box. Happy with my purchase.

Tested whistles. Very loud and shrill if you blow hard. Comes with 2 whistles, 2 long nylon lanyards, and 2 short nylon lanyards and 3 clips to lock the ends of the cords in place. The cords are easy to cut to any desired length. Once you clip the clips shut over the ends of the cord that is it, you cannot open them again as far as I can tell. This means you cannot use them to change the length of your lanyards. I do wish they had made a mechanism for the lanyard length to be adjustable. The whistles have a built in belt clip that is very tight. It would difficult to get them clipped to a thick belt or thick pack straps.

Excellent safety product. Easy to use, lightweight but tough, brightly colored, and a loud, very audible whistle. Got this based on recommendations from a survival site that discussed the fact that a pea-less whistle (without the little metal ball that rolls around inside) is much safer for water use because it can get wet/submerged and still function.” We tested it out and it was perfect— no difference between wet or dry, plus it floated. Love this! We’ve attached it to our backpacking packs, hydration packs, and emergency kits. As an active outdoor family, this is a great tool to help us be prepared for whatever happens.

- Small and low-profile plastic whistles. - A belt clip is integrated into the design, but I'm not planning on using this feature as I'm worried how well it would hold up to use. Probably great if the whistle is intended for emergencies and would only be removed from a strap or belt in an emergency. - The wrist lanyard is long enough for my fat wrists. Woot!!! - Seems loud enough. - Bright colors make it very easy for me to find in a pack.

Loud and requires very little effort to make noise. Clip allows me to attach it to my life jacket so it is always with me and within reach.

Whistles are fine and work well. Giving three stars because the lanyard shown in the picture was not what was provided. It was part of the reason I ordered this particular one. I ended up returning it.

Great value, solid construction, no regrets. The attached lanyard is perfect length for a life vest (personal floatation device). We tied these close to our mouths so we could blow them even if our hands were incapacitated. This would also work on backpack (or hydration system) shoulder straps the same way. These were so inexpensive I was a little apprehensive at first. But we tested them out and they are LOUD. Even when full of water, they clear out fast and get LOUD. My only caveat is you have to blow pretty hard to get the full volume. If you have young children or folks with compromised lung function please test these out before you have to rely on them for safety. Thanks for reading through. I hope this helps you make a smart purchase! ~Mahalo

Have tried this whistle just once , you have to blow real hard for the sound to be heard loudly - however did not notice any ear shattering sound as indicated in some other reviews

Works great

No noise except a fine little sound of air going through the whistle. My dog doesn’t respond at all
