A 3 MPH wind means a toxic gas can travel 264 feet in 1 minute!^* Ordinary windsocks cannot detect low wind movement, only the Wind Tracker Windsock System can.

Sets up in under 30 seconds, retracts to only 59", and raises up to 21 feet high. Great for first responders, fire and police departments, etc. Detects wind below 1 mile per hour!

This Wind Tracker 621 Pro™ comes complete and ready to use at ground level too. Use our portable base (fill with sand or water) on hardscapes allowing you to leave in place or change locations with just a small handcart, or use empty, and use the carry handles.

The Wind Tracker 621 Pro is versatile, and fits into any vehicle for transporting from one location to another. Great for pickup trucks, and off road vehicles. Use our portable base or wheel stand for added flexibility. With a twist of the wrist it telescopes closed, and the entire unit, pole, windsock, and patented harness slips into the handy carry bag.
