Radars Devices and Integration

Stack training requires a radar that can measure swings without ball impact.  While not all radar devices have this capability, this page will always be up to date with radars that can capture non-impact swings.

At The Stack System, we analyze nearly all radar devices that track training swings and TheStack App factors out any bias, or systematic error, in speed measurements that are associated with our hardware design.  What does this mean to you?  If your radar measures with a bias, our smart algorithms adjust for it and accurately calculate your eSpeed and Distance Potential regardless of which device you are using.

Sports Sensors

The Swing Speed Radar® by Sports Sensors is a radar that measures club-head speed only and gets the job done.  If you already have a Sports Sensors radar, you're all set to start with TheStack. For best results with your training, we recommend to upgrade to another speed device.  We like the Stack Radar.


The Yupiteru GST-5 W and GST-7BLE are Japan products that report speed in Meters / Second and allow training swings with TheStack.  TheStack App can be configured to dictate or enter your speed in M/S and record speed in MPH, so we are now compatible with the Yupiteru products.  You can purchase the Yupiteru GST-5 W here.
