HOW IT WORKS
Two infrared LEDs emit light pulses at extremely high speed in a carefully defined dispersion angle. The light is reflected off of the moving bat and back into the slots in the unit. The time it takes the bat to travel from one slot to the next is how the bat speed is precisely measured.
Remember, all the knob-based units, which are good at determining the exit velocity of a batted ball, are merely estimating sweet spot speed based on the movement of the knob and the inputted length of the bat. On a bat with the tip traveling at 100 miles per hour, the knob may be only moving around 20 miles per hour. This means that every point along the line of the bat is traveling at a different speed. Also, each player has a different hand path, so this adds to the error in their estimated speed of the bat’s sweet spot.
The tip of the bat is the only place on the bat where we can consistently, reliably and precisely measure bat speed. While the tip of the bat will always be moving faster than the sweet spot, the tip speed is the only place on the bat to accurately track progress in bat speed improvement over time.
Without accurate measurement, noticing very small improvements in bat speed is impossible. The Bat Speed Recon™ measures tip speed in increments of .1 MPH. Remember, you gain about five feet of distance for one mile per hour Internet speed improvement, so even .5 MPH improvement is very beneficial. Imagine a 5 or 10 MPH increase in your average bat speed.
