Stalker Radar Pro II Sensor

Stalker Pro II sensor

The Stalker Radar ProII Sensor is a sports radar that gives you tennis, cricket and baseball ball speed as well as vehicle speed, in a fixed mount package. Used extensively throughout Australia in state and national cricket centres.

Fully programmable via laptop or PC, when interfaced to a speed display it presents a formidable training tool no matter what level of sport you are working in.

Stalker Radar Scoreboard APP

Scoreboard Software provides a tool for displaying speeds, setting up the Pro II sensor and datalogging.
Combined with Bluetooth communications it gives the user the ability to remotely view data from the sensor in real time.

Pro II Hand held in a permanent mount package.
PC application available for configuration and communication
with the radar.
Reports speeds in MPH, km/s, knots, feet/second, or meters/second in whole units or tenths resolution.
Measures speeds up to 1432 KPH.
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 152 metres and average-sized automobiles to 2.8 kilometres.
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.
Connect multiple radars in point-to-multipoint configuration (RS-485)
Multiple streaming data protocols.
