This is hands down the best motion sensor , stat capturing device on the market.
The video option is beyond anything I have ever experienced thus far , and is completly in a place of its own.
Closest thing to it would be the my vert device , and due to my vert being able to track multiple athletes at once makes it a close second.
But, blast motions additional stat tracking and video places my vert miles behind it.
Blast motion is a must have for any serious trainer , coach or player.
