An indoor golf stance mat will bring your feet level with the unit. When your feet are even with the P3 sensor unit, you get the most accurate shot data from your swing. Our stance mats have been designed to surround the P3 so that you can keep your body aligned with the sensor unit. The stance mats and putting strips also fold for convenient storage. Please note: our stance mats are not designed to be hit. If you hit the mat you will likely damage them.
