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.

Customer Reviews of Bushnell Speedster Radar Gun
Requires some skill I see a lot of people have had trouble tracking baseballs with this thing. I've owned one for 3 years and it works pretty well. I will give some tips on it: <
> <
>!!!If you throw at a respectable speed, and don't follow the correct procedure it will not work - there will be no reading!! <
> <
>1) Don't stand behind a metal fence. The Chain links with the plastic coating over them will work, but for whatever reason exposed metal interferes with the signal. <
> <
>2) The focus beam of the radar gun is very narrow. The whole idea is to keep the beam on the ball as long as possible. Just having the ball pass through the radar beam is not enough. You need to keep the beam on the ball for practically the whole pitch. <
> <
>3) Use rechargable batteries... and this isn't to save money. Some of the better Energizer rechargable are high amperage, 1350 mA and up. The gun tends to respond better to this, as its pretty power hungry. You will get more consistant readings with better batteries. Non-rechargable batteries cannot provide the same level of current (usually 850 mA or less), which seem to effect the gun. <
> <
>So, how would you properly use the gun? <
> <
>One way is to stand behind the mound as the pitcher throws. Forget about using it during a game, behind the backstop. It wont work. <
> <
>Try line up the pitchers release point and the plate, then situate your gun so that it fires on this imaginary line (connecting pitchers hand and the target. <
> <
>You may have to slightly change the angle of the gun to track the pitch, which can be slightly tricky. Follow the ball with the gun as long as you can. <
> <
>For a sure fire way to clock a throw, get a cheap net and stand behind it. You will register it every time. You will also have the most accurate reading.
Does not work for baseball. Very frustrating.
When it was new out of the box it worked for baseball about 50% of the time if I was within a few feet of the pitcher or catcher. It seemed to become less effective each time I used it to the point that now I'm lucky to get a reading 10% of the time. It still works for clocking cars but for baseball it is almost useless.
Accurate...
This is a pretty accurate radar gun for baseball, as far as I can tell. If you follow the directions, and are as close to the action as possible, and at a "straight on" angle, it looks like its correct in the + - 1 mph statement. However, this is a cool gadget, but if you are serious about "speed" and would like more versatility, then your going to have to go with the official MLB JUGS gun...but at a much higher price.
