DRAWING FROM THE DESIGN ETHOS (AND TRICKLING DOWN TECHNOLOGIES) OF OUR CORE PRO PUMP, THE CORE 3 IS A MORE ECONOMICAL PUMP WITH THE SAME BASIC FUNCTIONALITY OF THE PRO. IT’LL FILL ANY TIRE VALVE YOU CAN FIND QUICKLY AND ACCURATELY THANKS TO THE OVERSIZED PUMP SHAFT, EASY-TO-READ 3-INCH-TALL AVIATION PRESSURE GAUGE AND THE INLINE BLEED BUTTON ON THE AIRTAP HEAD.
