That is the unlock for Stack speed training (where you swing weighted training clubs and need a measurement device that can read the swing in the air). Beyond Stack work, the Radar measures four standard metrics on real shots: swing speed, ball speed, carry distance, and smash factor.\u003c\/p\u003e\n\n\u003ch3\u003eWhat it does\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eDoppler radar measurement of swing speed (with or without ball)\u003c\/li\u003e\n\u003cli\u003eBall speed, carry distance (estimated), and smash factor on struck shots\u003c\/li\u003e\n\u003cli\u003ePowers Stack Wedging gamified practice mode (iOS) for accurate wedge feedback indoors or outdoors\u003c\/li\u003e\n\u003cli\u003ePairs with TheStack App via Bluetooth for temperature and altitude adjustment\u003c\/li\u003e\n\u003cli\u003eConfigurable speed trigger (25, 35, 45, or 55 mph) to avoid false reads\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eDesigned and developed by Dr. Sasho MacKenzie (PhD Biomechanics, golf's leading speed researcher) and Marty Jertson (lead engineer at PING for 20-plus years, six-time Major Championship competitor).
