The Hyperwhistle will find plenty of use, from safety, to sports, to survival\u2014and more. Claiming to be the world\u2019s loudest whistle isn\u2019t a boast. The Hyperwhistle blows away the competition with a whistle measuring in at 142 decibels. At that level, the Hyperwhistle can be heard over a more than two mile range\u2014that\u2019s eight times the range of a common sports whistle. Fortunately, the Hyperwhistle comes with hearing protectors for the user (you\u2019ll also receive an easy clip neck lanyard).\r\n\r\nYou might suspect that the Hyperwhistle is some monstrously huge contraption, but it actually only measures 3.3 inches in length and 1.3 inches in diameter. It fits comfortably in your hand, or can be held easily in your mouth hands free (it weighs less than an ounce). Made of a durable composite polymer, you can use the Hyperwhistle in the water\u2014in fact it even works under water.\r\n\r\nFinding a use for the Hyperwhistle is easy\u2014law enforcement, personal safety, sporting events, search and rescue, border and port authority, boating awareness, traffic control, naval deck alert, wilderness activity\u2014the list could go on and on. If you need a whistle that will be heard no matter what the circumstances, then the Hyperwhistle is your best bet.\r\nCheck it out\r\nHave you subscribed to Man of Many?
