How to test Swingbyte vs. radar-based systems
We hold Swingbyte’s accuracy to the highest standards - accurate, meaningful, and actionable information is essential for improving faster!
To ensure Swingbyte’s accuracy, we have spent countless hours testing Swingbyte’s output relative to golf’s other leading technologies: high speed cameras, radar-based ball launch monitors, other on-club sensor systems, etc. There are nuances to each of these technologies, and they must be carefully considered when comparing the results of one system to another.
Given the availability of radar-based ball launch monitors, field-testing of Swingbyte relative to those systems is both common and welcome. While Swingbyte has never and will never suggest that it is a perfect mimic for the outputs from any other technology, we believe that cross-testing technologies offers many benefits. The most important of which is to confirm the trust you should have in Swingbyte’s accuracy and consistency.
If you are so inclined to compare the data from radar-based data systems (RBS) and Swingbyte’s, follow this protocol to ensure the most accurate comparison:
CLUB HEAD SPEED: To ensure the most accurate club head speed calculation in Swingbyte, accurate club length and shaft flex must be entered for your Swingbyte clubs. Further, the correct club that you are using to hit golf balls must be selected in the Swingbyte app. Swingbyte’s Club Head Speed calculation includes extensive shaft flex data across all flex categories. While this robust library is a decisive advantage for delivering the most accurate club head speed calculation with on-club accelerometers, gyroscopes, and magnetometers, there may be some variance relative to RBS due to differences between your “S” shaft and the aggregate category shaft data.
ATTACK ANGLE: Attack Angle requires two points to determine a line that is then compared to the horizon. To determine this line, Swingbyte uses the point of impact and one millisecond before impact. We understand that RBS use a point or points forward of impact to determine Attack Angle. Therefore, Attack Angle is not an apples-to-apples comparison between technologies and will typically be a minute or so steeper on Swingbyte than RBS (1 minute = 6 degrees). Further, “impact” is exactly that - the first point of contact in the downswing. For golfers of all skill levels, this is not necessarily always the golf ball.
CLUB PATH: Swingbyte uses the clubface direction at address to determine a target line. RBS use a fixed target line based on where the unit is aimed. These are the target lines against which a Club Path # is determined. Given that golfers rarely aim the clubface directly at their intended target, clubface aim at address must be accounted for when comparing Club Path #’s between the two systems. Here’s how:
1) Hit golf balls off a lie board. Many top teachers who use radar-based ball launch monitors in their teaching advocate using a lie board so that divots do not interfere with the radar.
2) Align the lie board’s target line perfectly with the radar system’s target line.
3) With Swingbyte properly aligned on the club, align the clubface perfectly perpendicular to the target line on the lie board…This is not necessarily a recommended golf fundamental. It is essential, however, for neutralizing the target line differences between the two systems.
4) Make contact with the golf ball first. As mentioned above, Swingbyte uses the first moment of impact to determine impact data.
Even with the above protocol in place, the Club Path numbers are unlikely to perfectly mimic each other. The differences include the variance in aligning the lie board to the RBS, the Swingbyte to the clubface, and the clubface in a perpendicular fashion to the lie board’s target line. Further, as discussed in Attack Angle, Swingbyte measures impact at a slightly different point in the swing circle than RBS.
Although a perfect apples-to-apples comparison requires great care and is difficult at best, by following these steps Swingbyte’s information will prove to be directionally consistent - swing faster or slower, steeper or shallower, more from the inside or outside, and Swingbyte will show you the appropriate change.
