Radar Devices and Integration

Stack training requires a radar that can measure swings without ball impact.  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.

Regardless of your distance, the PRGR is a great unit training with TheStack.  It is small and packs into your golf bag easily, and gives the added benefit of being a great device to bring onto the golf course to measure ball speed while playing.  Nearly all of our Tour players use the PRGR.
