High Performance Sports Radar Gun
The Choice of Professionals

The versatile Stalker Pro II is the choice of Major League Baseball and top-level collegiate and Semi-Pro teams worldwide. The Pro II quickly and accurately measures the speed of anything moving through the air, over land, or on the water. The one sports radar that does it all!

No other sport radar is as accurate, sensitive, or has as much range and versatility as the Stalker Pro II.

Baseball Mode - 500 Foot Range!
The bi-directional Pro II measures the peak (release) speed and plate (roll-down) speed of a baseball pitch, as well as the speed of a batted ball traveling in the opposite direction. All three speeds display at the same time.

Vehicle Mode:
Clock vehicles on land or water up to two miles away. The Stalker Pro II filters out other vehicles moving in the opposite direction of interest.

Carnival Mode:
The Pro II attaches to the side of a backdrop and measure the speed of midway game balls thrown from only a few feet away.

Tennis Mode:
Track balls on any side of the court, as the Pro II’s wide beam width measures both the ball’s peak (serve) speed as well as the decelerating live speed.

The Pro II High Performance Sports Radar package includes:

  • The Stalker Pro II sports radar gun
  • Rechargeable Li-Ion battery handle
  • Hard plastic carrying case
  • Battery charger
  • Operators Manual
Price: $1,477.00
