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.

Swing Caddie   TheStack preferred 

If you hit your driver 275 yards or less (driver swing speed < 100 mph), the Swing Caddie SC200 Plus makes for a seamless Stack training experience.  The Voice Output from the Swing Caddie will speak your Stack training speed, and TheStack App will listen for it using our Voice Entry technology so your data is read in seamless while you get the audible feedback while training.   Click here to see this in action.

The SC200 Plus+ doubles as a portable launch monitor that measures swing speed, ball speed, and estimated carry distance.  You can order a Swing Caddie here.

*note: The SC200, SC300, and SC300i can not capture training swings, just the SC200 Plus+.


If you hit your driver 275 yards or further, 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.
