The Stack System Radar Portable Golf Launch Monitor — Compact Bluetooth swing & ball speed tracker

TheStack™ Radar is a compact, Bluetooth launch monitor that records swing speed, ball speed and estimated carry distance so golfers can train with accurate speed metrics on range and course.

Small enough to bring to the range or drop in your bag, TheStack Radar pairs with TheStack App to stream speed data live to your phone. It’s designed for players who want objective feedback—track smash factor, monitor progress, and use guided practice modes including Stack Wedging and Stack Putting (app features vary by platform).

How does TheStack Radar measure my swing and ball performance?

TheStack Radar uses radar sensing to capture swing speed and ball speed, then derives metrics like estimated carry and smash factor from those readings. Measurements appear in the app immediately so you can see results shot-by-shot.

• Records swing speed and ball speed with rapid radar sampling
• Calculates estimated carry distance and smash factor
• Delivers shot-by-shot numbers to the app via Bluetooth

What training tools are available through TheStack App?

TheStack Radar links directly to TheStack App for live data and structured practice. iOS and Android support speed training; Stack Wedging and Stack Putting features offer guided routines and insights, with some modes currently iOS-only.

How portable and easy to use is the launch monitor on the course?

TheStack Radar is built for portability and straightforward operation—set it behind the hitting area, pair to your phone, and start swinging. Its compact size and quick Bluetooth pairing make it practical for range sessions or measuring speeds during rounds.
