The Stalker Sport Exclusive Spin Rate

Professional and college athletes, coaches, scouts, and serious parents have relied on Stalker Sport radar technology for decades.

Our Pro S series radars are the only handheld radar guns that capture spin rate. And because they also measure peak velocity, rolldown, and exit velocity, they give you every velocity measurement you need to track to improve your game.

The Stalker Pro Series sports radars are the only handheld sports radars on the market that capture Spin Rate. The Pro 3s features an enhanced algorithm that delivers spin rate faster than ever, with greater accuracy from a variety of positions up to 150′ (42 m) away.

Rolldown

Measure Over-the-Plate Velo to observe how your Velocity changes as the ball travels.

Peak Velocity

The Stalker Sport Pro 3s gives you the most accurate handheld Velo measurements available in the sports world – and it can capture accurate Velocities from up to 500′ (152 m) away.

Exit Velocity

Select Exit Velocity instead of Spin Rate if you’d like to measure hit speed. This allows you to use your sports radar to measure velocities both coming towards you and moving away from you with one pull of the trigger.

Spin Rate

The Stalker Pro Series sports radars are the only handheld sports radars on the market that capture Spin Rate. The Pro 3s features an enhanced algorithm that delivers spin rate faster than ever, with greater accuracy from a variety of positions up to 150′ (42 m) away.
