The evolution of PROTREK never stops. These new models embody some of the very best in functional beauty and ease of operation that modern technology has to offer. The rotary bezel is specially shaped for easy operation, even while wearing gloves. Large letters indicating north, south, east, and west are colored for easy reading. Dedicated direction, barometer, and altitude buttons provide one-touch access to measurements. Buttons are large with slanted diamond patterns for plenty of slip resistance during operation. Since quot;easy to pressquot; often also means quot;more operation errorquot;, the back cover is designed to make it the same height of the button surfaces, which greatly reduces the chance of operation error.
