The ITW Survival Whistle is capable of producing over 100 decibels of sound to summon help in emergency situations. The ITW Survival Whistle is equally at home on land, sea, desert, jungle or city streets. It is the ultimate safety whistle.
I set up a test, where each of the persons I gave one to stood a different locations on a normal day, and at various distances up to half a mile away.
I was in the center; when I called each person on their cell phone, the took turns doing one short blow of the whistle, then three long ones, and one short one.
Then, each person took note of how well it was heard.
In a normal "suburban" area, I could hear each one!
How's that for "keeping in touch"?
Nice to have for the daughter and grand daughter. Great sound.
Great whistle to get the attention of my dogs. Loud enough but not too loud.
Great - loud and clear
I've purchased a couple of these for survival kits that I keep inside of my backpacks. This is a well-designed and competitively priced whistle that's an essential item for all adventurers. You can't go wrong with this purchase.
