Sport Sensor 3s & Stadium Hub

Stop Guessing. Start Measuring.

The Sport Sensor 3s and Stadium Hub bring that same trusted accuracy into a permanent installation without the complicated camera rigs, the bulky hardware, or the complex setup of the big systems.

Peak Velocity, Rolldown, Exit Velocity, and Spin Rate. All four metrics. One system. Connected to the same Stalker Sport App your coaches already use on the field.

If your program runs a Pro 3s at the field, the Sport Sensor 3s at your facility speaks the same language. Same app, same data stream, one ecosystem from practice to game day.

The Metrics That Matter, At A Price That Makes Sense

Your players deserve the same data the big programs use. Now they can have it.

Capture what counts:

Peak Velocity. Our Accurate Angle Technology ensures that your velos are dialed in for accuracy
Rolldown. Track velocity change across the plate so coaches can make adjustments that stick
Exit Velocity. Now you can view both exit velocity and spin rate with no need to choose between the two
Spin Rate. View your spin rate instantly, because the perfect pitch is about so much more than sheer velocity
