Blast Motion recently took part in a third-party validation test to verify its accuracy against the top two baseball swing sensor competitors on the market: Diamond Kinetics and Zepp. The results from The Center for Human Performance are in. And they confirm the earlier findings:
• Blast’s swing sensor is the most accurate baseball sensor on the market.
• Dynamic calibration makes the Blast sensor much easier to use in an athlete’s natural environment than any available alternative.

About the Center for Human Performance
The Center for Human Performance is a state-of-the-art motion analysis institution based in San Diego, CA. With expertise in kinesiology, biomechanics, engineering, athletic training, and orthopedics, the Center offers a comprehensive suite of sports science and motion-capture services – all backed by extensive experience and clinical research. Center Director Arnel Aguinaldo also serves as Assistant Professor, Kinesiology at Point Loma Nazarene University and VP of Applications Development for Motion Analysis Corporation.
An Accurate Baseball Sensor? The Swing Sensor Comparison Study
Led by Aguinaldo, the study compared the baseball swing sensor and analyzer of Blast to those manufactured by chief competitors Diamond Kinetics and Zepp. Fifteen male college and minor league baseball players over the age of 17 swung a 33-inch, 30-ounce baseball bat equipped with four reflective markers, allowing for 3D motion analysis of the bat during each swing at a sampling rate of 300 Hz. Each of the three swing sensors was attached to the bat in random order and the 15 subjects all hit a baseball off a tee 10 times with each sensor – while marker locations were captured from the motion-capture system.
All trials were performed inside a 100-by-15-foot enclosed batting cage. Baseball swing data was recorded from each sensor using each respective sensor’s mobile apps – then compared to Motion Analysis MoCap camera 3D motion-capture data to measure the error in swing speed (i.e. degree of accuracy).
An Accurate Baseball Sensor Defined: About the Test Results
Blast consistently outperformed its competition in several areas of the swing sensor study the most important being accuracy and ease of use.
Accuracy: When it comes to swing sensors, accuracy is the name of the game. It’s the key metric in play, and was the main focus of this study. Blast’s swing sensor exhibited the lowest margin of error – and was significantly more accurate than Zepp’s sensor. Blast’s standard deviation was 3 mph, compared to 5 mph for Diamond Kinetics and 7 mph for Zepp.
Setup time: Setup time for Blast’s sensor was a mere 90 seconds, on average. Diamond Kinetics’ sensor setup, on the other hand, took anywhere from 5 to 10 minutes, due to more involved calibration procedures. Talk about a big difference.
Leading-edge accuracy, paired with the invaluable ability to not disrupt the natural routine of athletes and coaches, makes Blast the best swing sensor solution available to hitters on the market today.
