Olight Otacle Owhistle 2 Titanium Multifunctional Emergency Whistle with Compact EDC Compass

2 Tools in 1: It functions as a whistle and a compass. Constructed from lightweight, corrosion resistant TC4 titanium alloy in a sandblasted finish. Dualtube design makes the whistle louder and lets it reach up to 100+ decibels at a 0.5-meter distance. Built-in compass with 10-degree increments is ideal for navigation and orientation. You can change the color of the titanium surface to your liking by heating or oxidizing. Included key ring easily attaches the whistle to a bag, belt, or keychain. Key ring is also made of TC4 Titanium material so it will not interfere with the magnetic field around the compass.
