The Field Expedition One kit includes the unique 3-in-1 Compass Tool. It clips to your Cargo Vest with a retractable carabiner. A push button releases the spring loaded lid revealing a field compass. The reverse side features a bright LED flashing signaling light that lets you flash Morse Code across a distance. The code is printed right in the lid. Finally, a magnifying lens folds out from a hidden space allowing you to do close-up study in the field. This special edition kit comes with the collectible Expedition One iron-on patch and the Expedition One Pop-Up Field Guide that features instructions for completing special missions in the field.
