The Stalker Sport Pro 3s
Connect With the Game Like Never Before.
Enhanced Spin Rate Performance + Multiple iOS Connections +
2X the Wireless Range
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.
Spin Rate Technology
Patented by Stalker Radar
The Stalker
Pro 3s
The Pro 3 has an enhanced spin rate algorithm, allowing it to measure spin rate faster, with greater accuracy, and at farther distances.
You can also now connect up to 10 iOS devices to one radar gun at the same time, allowing more players, coaches, scouts, and parents to get in on the action.

What Gets Measured, Gets Improved.
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.
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.
Real Sports Radars Don’t Fit
In Your Pocket.
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.
Not Just For Baseball…
Use Your Pro 3s to capture velocities in many other sports, including:
- Softball
- Tennis
- Pickleball
- Football
- Volleyball
- Soccer
- Cricket
- Archery
- Shooting Sports
- Track and Field

- Cars, Snowmobiles, and other Vehicle Racing
…and so much more!
