Stack Radar is a portable doppler radar launch monitor designed for the everyday golfer. The same K-band doppler technology used in premium launch monitors, in a compact form factor that packs into your golf bag.
What makes Stack Radar specifically useful for The Stack System: it captures swing speed without ball contact. 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.
What it does
- Doppler radar measurement of swing speed (with or without ball)
- Ball speed, carry distance (estimated), and smash factor on struck shots
- Powers Stack Wedging gamified practice mode (iOS) for accurate wedge feedback indoors or outdoors
- Pairs with TheStack App via Bluetooth for temperature and altitude adjustment
- Configurable speed trigger (25, 35, 45, or 55 mph) to avoid false reads
Designed 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). TheStack ecosystem has tracked over 45 million swings from 50,000-plus users, with an average clubhead speed gain of 10.1 mph (equating to 27.1 yards in driver distance potential).
Purchase includes a 1-month free trial to Stack Wedging (iOS), plus bundled access to Stack Putting (iOS) and the Learning Library. Full Stack Wedging and Putting features require TheStack Speed Trainer hardware (sold separately or in the bundle).
Stylized carry case included (exclusive to direct purchase from the website). Trade-in program available for current Stackers upgrading their launch monitor.
