The Coollang Personal Tennis Training Kit contains two basic parts:
- Movement sensor, which records your shot data, and transmits the data to your smartphone via Bluetooth, either real-time or at later stage.The internal memory of the tennis sensor can store up to 100,000 shots, and the internal battery lasts around 6hr per full charge.
- Smartphone APP, available in both iOS and Android versions. It reads and analyses your shot data from the sensor, then generates relevant reports/graphs. It can also utilize your phone camera to record your training video, then incorporate the shot data from the movement sensor to give you a visual demonstration of your performance. The APP also provides other training contents and social functions.
Here is a Video to give you a glimpse of how the training works:
