ETRAK is a compact wearable device which integrates a 10-axis IMU (accel, gyro, mag, and pressure) to provide accurate trajectory tracking. The company has created this technology to help measure and improve golf swing performance, allowing users to set baselines for repeatability, power, and other metrics, then compare performance to these baselines over time or against other athletes. From the ETRAK website:
The human body is complicated and technology can be overwhelming. We also know golf is a very specific sport. Small changes in the right place make a big difference but with so much information available for instructors, it’s hard to find an efficient system that really works. Our system helps you save time, get better results, increase your golf teaching revenue, and be the best instructor for your students.
The ETRAK Phoenix device connects to an iOS smartphone app which records and analyzes the data using proprietary metrics developed by the ETRAK team. Learn more about ETRAK on their website here.
