Average Reviews:
(More customer reviews)this radar gun is pretty good. It is easy to work and use. The only problem with it is that it is very ocward to hold and sometimes it doesnt read speeds right. I used it to rad the speed of hockey pucks and it did pretty well considering that they are small. It works great for cars but it cant read much over 135mph. This is a nice gun but if you want the best gun this is not it.

The Bushnell Speedster is a handy, multifunctional speed gun for all sports enthusiasts. It tracks the speed (in mph or kph) of everything from pitching speeds, tennis serves, and downhill skiers to cars at the racetrack. It can measure the speed of a baseball going 6 to 110 mph from over 75 feet away and the speed of a racecar going 6 to 200 mph from over 1,300 feet away. The Speedster also enables you to keep statistics for baseball and softball.
It features a highly legible, four-row LCD graphic display, a trigger, and a two-way button pad. The Speedster uses digital technology and DSP (digital signal processing) to provide instantaneous and real-time speed measurements with an accuracy of +/-1 mph.
Speedster FAQ
What is the Bushnell Speedster used for? The Bushnell Speedster can be used to accurately measure and display speeds of many of your favorite sports. It can track speeds of baseballs, softballs, tennis balls, and can be used in ice skating, auto racing, horse racing, track, and other sports where speed is crucial to success.
What technology does the Speedster use? The Bushnell Speedster contains a K-Band microwave RF (radio frequency) transmitter whose signal gets reflected by the target object. The reflected signal will have a Doppler shift proportional to the target speed. This Doppler frequency shift is detected in the receiver, amplified, filtered, and then digitized in an analog-to-digital converter (ADC), and passed onto the digital signal processing (DSP) chip. Using complex algorithms, the DSP chip filters out false and low-level return signals to identify the speed of the desired target. The speed, along with various statistics and averages, is then displayed on the LCD.
What is radar? Radar is an acronym for radio detection and ranging.
How does the Speedster work? Once you press the trigger, the Speedster sends out 24 GHz radio waves at the speed of light, which is 186,000 miles per second. It measures the difference between the signal it transmitted and the signal bounced back to it and relays this information to the DSP to quickly calculate the speed of the object with an accuracy of +/-1 mpg.
How is speed calculated? Speed is calculated using the difference between the transmit frequency and receive frequency (also known as the Doppler shift).
How accurate is the Bushnell Speedster? The Bushnell Speedster is accurate to within +/-1 mph.
How does the user need to be positioned in relation to the moving object? The Bushnell Speedster works best when positioned in front of or behind the moving object.
Can radar guns determine the speed of an object moving in any direction? No, Doppler radar can only determine the relative speed of targets moving either toward or away from the radar.
Does angle affect accuracy? A 12-degree angle should not affect performance. The Speedster is accurate to within +/-1 mph for a baseball 75 feet away at an angle of 12 degrees or less. A 20-degree angle at 60 feet away would result in an accuracy of +/-3 mph.
From how far away can the speed of a baseball, softball, or tennis ball can be determined? 0 to 75 feet.
