The Stalker Pro II Speed Sensor
Powerful, fixed-location speed sensor for stadium and scoreboard applications for multiple sports
The Pro II Speed Sensor is a complete and highly-accurate Doppler Radar. Designed in a rugged, waterproof housing that can measure the speed of a wide variety of objects including baseballs, softballs, tennis balls, hockey pucks, etc.
It combines features and performance of the Stalker Pro II handheld sport gun with the Sport Speed Sensor configuration.
The unit is available in a RS-232 model and includes complete software support.
Stalker Radar Application Software
A PC application is provided to configure, control and monitor the Stalker Pro II Speed Sensor. This is the cornerstone of the PRO II Speed Sensor Developer’s kit.
- Clean and clear graphics for displaying sensor readings.
- Easy to navigate for setting sensor configuration.
- New detailed users manual to guide the user through the program’s operation.
- Upgrade a sensor’s software from within the application.
- Automatic sensor and Baud rate detection.
- Same performance as the Major League favorite Pro II Hand held
- Waterproof IP67 design
- PC application available for configuration and communication
with the radar. - Reports speeds in MPH, km/h, knots, feet/second, or meters/second in whole units or tenths resolution.
- Measures speeds up to 890 MPH.
- Directional – tracks objects moving in either direction.
- Reports Live (Rolldown), Peak, highest peak speeds in one direction, or hit speeds in opposite direction.
- Detects baseballs to 500′ and average-sized automobiles to 1¾ miles
- Wide range of High and Low Speed Thresholds to focus on speed range of interest.
- Tracks everything from car-sized objects (and larger) to BBs.
- Automatic cosine angle adjustment compensates for both off-horizontal and off-vertical angle readings
- Waterproof; Ka-Band, 34.6 GHz; 15mW nominal power output; ±0.3% accuracy.
- A, A1, b, bE, and S streaming data protocols.
