Stalker Pro IIs hand-held radar gun to capture SPIN RATE and VELOCITY

The Stalker Pro IIs goes where no other sport radar has gone before. It is the only hand-held sports radar gun that measures baseball spin. No delay, no estimations, simple measurements. And it does it as quickly and easily as it tracks peak or across-the-plate velocity. Now you can take this all-important pitching metric with you whereever you go. Add to that, built in wireless connectivity makes the Stalker Pro IIs unmatched to any other device.

Reliably accurate baseball spin readings with no delays and no estimations, plus release speed and across-the-plate speed. You get all three displayed in one easy-to-read window.
