It's a whole new ballgame!
Accurate Spin Readings
Capturing the spin rate of a baseball or softball with a hand-held sport radar gun is only possible with the Stalker Pro S Series radar guns. That’s because Stalker engineers have delivered what the other handheld sport radars can’t: 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.
Ask any Scout
Built on the legendary Stalker Pro II platform, the Pro IIs not only delivers accuracy, but dependability and durability. Pitch after pitch. Game after game. Season after season. Just ask any pro scout. They’ll tell you why every Major League Baseball team uses Stalker Sport Radars.
You can’t do that with
one-button radar
No delay
Nothing has recently captured the baseball community’s interest like “spin rate.” That’s why Stalker placed such a priority in developing spin rate technology for its hand-held Pro IIs radar. Now you can measure baseball spin rate whenever and wherever you take your Pro IIs. You can’t do that with a one-button radar. The Pro IIs software detects and counts ball revolutions for the most accurate reading possible. And there’s no lag between speed measurement and RPM display. It happens just as fast as the speed readings are displayed!
It goes where you go
So now, location doesn’t matter. Spin rate measurement goes where you and your Pro IIs go. It’s fast, easy, and requires no setup.
