The Arrow speed Radarchron is a small, (3 ounces) Doppler radar that attaches to the bow and measures the speed of metal and graphite/carbon arrows. It is accurate within 2% over a range of speeds from 150 feet per second to 450 fps. Rugged, compact design make it convenient to carry and use. Attaches to most compound bows via hardware (furnished) that interfaces with the 5/16"-24 threaded mounting holes at the end of most stabilizers. An extension rod is also supplied to be used in place of, or in tandem with a stabilizer. Just turn it on via a simple push-button; shoot your arrow; and measure the speed . Adjust your bow and sight and select the best arrow for the optimum shooting conditions at the target competition or the hunt
