Prometheus Design Werx Ti-Signal Whistle Review

Nowadays, everyone carries a phone almost everywhere they go, but how often does that phone work in the wilderness? How easily can it get damaged or run out of juice? Before phones and radios, whistles were used for call-and-response communication, emergency signaling, and as a locator for potential rescuers. Even today, they’re a key piece of kit if you’re out in the wilderness for any length of time, even if you don’t plan on putting yourself into a situation where you think you’d need one.

Prometheus Design Werx has just released their version of the signal whistle, machined from solid 6AL-4V titanium billet in their Mk2 Pineapple pattern, which you can find on some of their other tools if you want to get matchy. This means that you’ll be able to easily maintain your grip in any weather conditions and the corrosion-proof, lightweight titanium will last, as long as you’re concerned, forever.

The PDW Ti-Signal Whistle comes packaged in a padded tin adorned with the PDW logo. The presentation is high quality, but I’d probably store the whistle somewhere at the ready unless you’re looking for a shelf piece (which this would totally qualify for).

You can easily keep the Ti-Signal Whistle around your neck on the provided stainless steel ball chain necklace, on your keys with the mini ball chain ring, or just strapped to your pack with the PDW Mini Coil Lanyard. It disappears when you don’t need it. At only half an ounce and 2″ in length, even ultralight hikers won’t notice the change to their base weight. 

Despite its small size, the Ti-Signal Whistle is loud – easily loud enough to be heard over a mile away through trees and over hills. Our basic testing puts it well over 100db. It’s also loud enough to drive any cohabitating animals crazy, so I wouldn’t walk around the house testing it.

At only $29, it’s a no-brainer addition to your outdoors kit given the bombproof titanium billet construction. Give yourself, your children, your grandchildren, and your grandchildren’s grandchildren some peace of mind.
