The Stalker Pro II Speed Sensor is a stationary Doppler radar built for facilities that demand elite precision. Housed in a rugged IP67 waterproof enclosure and built on the same proven technology as Stalker's Pro Series handheld radars, the Pro II turns a stadium, training center, research lab, or elite program into a permanent speed laboratory. It tracks objects moving in either direction from 1 to 890 MPH (1–1,433 km/h) — everything from baseballs, softballs, tennis serves, and hockey pucks to automobiles at ranges up to 1.75 miles. Speeds report in MPH, km/h, knots, feet/second, or meters/second at whole or tenths resolution, across multiple streaming data protocols. Every unit includes an RS-232 developer kit with full PC software support, so you can integrate continuous speed data directly into scoreboards, training systems, research applications, and custom builds. Where temporary solutions fall short, the Pro II delivers continuous, professional-grade measurement — indoors or out, in any conditions.
