To chime-in on Joey's tip...smart idea to have on hand for us city dwellers (and pepper spray, on-board biking, too). Also, even in our big-city parks, there have been more & more coyote & even black bear in the burbs (!) which even though normally won't bother the two-legged animals; you just never know (even the rangers have posted signs suggesting to carry a whistle for this reason). This little item could make a big difference in out-come! Good for all of the other obvious reasons, too!
I think this is the best whistle you can get. It is so inexpensive and you should have one for any outdoor activity - hiking, biking, boating, diving, etc. So get a bunch of them. It is loud! And easily attaches to a pack, BCD, hydration pack, whatever. No excuse not to always have one of these with you. it could save your life - or at least minimize your misery or frustration. Make sure everyone in your party has one too!
This thing is nowhere near the 40 grams claimed in the tech specs over there. I put it on my digital kitchen scale and it weighed in at 7 grams, with the little lanyard included. Light enough that you (quite literally) won't even notice you're carrying it. Oh, and it's loud and small, and the lack of a pea makes it so it won't rattle around in/on your pack. well worth 2.50.
You get more than you pay for. I keep one of these in my camera bag, one in my ski touring pack, and one in my mountain biking backpack. Never hurts to have a way to signal your friends or signal for help. The bonus: this method of signaling for what you need doesn't depend on batteries.
Gotta love this whistle. Although not the loudest I've ever tried, it's orange, small and able to be used on a lanyard /zipper. What more could you ask for? They outta make one glow-in-the-dark. but man this rules. I'm a survivalist and highly recommend this.
There's no reason not to have one.
VERY LOUD. I tried it full bore inside and rang my ears. lol The dog ran and hid under the bed. :)
Super lightweight, no pea to come loose. I just bought four of them and will grab a few more for putting into 72 hour kits.
Im a ski patrol and use it a lot, its a great product, and incredibly cheap!
Works great even if theres some water inside. Remember that the best place for a whisle is on ur shoulder, so u dont need ur hands to use it!!
I needed a better whistle for canyoneering besides the old ball whistle. This works great and is nice and cheap. Now to find a way to attach it to my helmet so it is easily accessible without it smacking me in the face...
...it's loud. For years I used a Fox 40, but then someone dropped it overboard. This is a great replacement.
Serious bonus points for using a sheet bend on the lanyard.
i keep this for those nights where you have to walk through the parking lot to get to your car in shady neighborhoods.
