Anyone tried? Does it actually work?

Description:
How hard can you shoot a hockey puck? Do you think you have what it takes to compete with the Pro's? It's time to put your strength, power, & speed to the test and blast your hardest slap shot. Simply measure your shooting distance, set your mobile device and fire away. Our state-of-the-art sound and speed measurement system will track the puck and instantly measure your speed. Can you break the NHL record 105.9 mph slap shot? Challenge your friends and post results on Facebook and Twitter.

Disclaimer - The NHL Hardest Shot app is designed for shooting distances of 20 ft and 40 ft. Any shot not taken at 20 ft or 40 ft could result in a failed trial or could lead to an inaccurate measurement of your shot speed.

I tried it, but I couldn't figure out how to set it up to test the speed. I have an iPhone.

If you want to save $2:

- measure the distance between the puck and whatever it's going to hit (preferably something loud like boards)

- record the audio any way you like

- analyze the file (say open it up in Audacity, a free audio analyzer) and get the exact time between impact with the stick and impact with the boards

If you did this in Imperial units, measuring distance in feet and time in seconds, simply divide the distance by the time. Then multiply by 0.682.

Ex:

Distance = 40 feet
Time = 0.34 seconds
Speed = 80.2 miles per hour

The accuracy would depend on the accuracy of your measurement and recording device. Probably within 5 mph I'm guessing.



Kind of a cool idea. I remember we did this with video frames a couple years back but this seems even easier to do, so long as you have a tape measure.
