About Highgear
Highgear was born in the Appalachian Mountains in 1999, when outdoor enthusiast Mike Hosey had a vision to create his own unique line of compact and affordable outdoor navigational tools. Aiming to enhance customer's experience of the natural world, Highgear evolved significantly in 2001. Watches, hand-held navigational devices, and pedometers were added to the product base, while infusing the entire line with top-notch design. The people at Highgear are passionate about the outdoors and spend their time skiing Sugar Mountain, biking Bent Creek, hiking Pisgah National Forest, and paddling the French Broad River. All products are field tested and measured for durability, accuracy, and reliability. Then, hours are spent brainstorming on how to make improvements on intuitiveness, design, and function. The result is a line of high-performance tools that makes outdoor adventure easier and more fun.
