The Pocket Radar itself is incredibly easy to use. Also, if the button has not been pushed in 30 seconds, it will automatically power down to conserve the batteries. Once you power up the Pocket Radar, you will be given a reading of the previous measurement since the device saves the last 10 speed measurements. Each set of batteries is good for about 10,000 speed readings. To get started with the Pocket Radar, you simply need to put in the 2 AAA batteries.

According to their site, you get more radiation from a Bluetooth headset or by standing next to a microwave oven. The Pocket Radar sits in an off position until you press (and optionally hold) the red measurement button. In terms of safety, the amount of energy that comes from the Pocket Radar is actually much less than you have emanating from a cell phone, especially when you are having a conversation.

There is a great chart in the User Manual (which is quite detailed by the way) that shows how the angle of the object can affect the “measured speed”:Īnd to put it all into perspective, below is an example of the variance of calculating a baseball pitch speed: Be sure to practice your speed measurement safely.
Remember though, that this can be dangerous so don’t jump out in front of a car driving towards you. In order to get the most accurate reading, the object needs to be as close to in-line as possible. In order to receive an accurate measurement, you can’t have the object passing in front of you (like left to right for example), because you can’t get the change of distance between the Pocket Radar and the object. Once these beams hit an object, a smaller portion of them are bounced back and the Pocket Radar receives these and quickly calculates the speed of the object based on the difference between the two waves. How does it work? Essentially it sends out a tiny, invisible pulse of radio waves the second the big red button is pushed. According to the documentation, it is accurate to within 1 MPH and can detect speeds between 7 and 375 MPS. Using a combination of Doppler radar and microwave and antenna components, the Pocket Radar delivers quick results, and they seem to be right on the mark from my non-scientific testing. So is the Pocket Radar really that accurate? Well I would definitely say that it is. It was pretty fun to see who could go faster, but do note that when you have these types of racing or speed contests, there is the risk of being a bit out of control and possibly crashing, so be sure you are wearing helmets and keep things under control. Later we took our bikes to a playground and practiced racing as fast was we could toward the person holding the Pocket Radar. But we were able to determine that it is about 18 mph. This type of test is particularly difficult because of the circular motion and it being a bit hard to be behind or in front of the fan to accurately determine the speed. When I first took the Pocket Radar out of the box, the first thing that my daughter and I tested was the speed of the ceiling fan.

The most obvious use case that comes to mind is that of a baseball pitch. When you think about it, having the ability to get the speed of any object can be quite useful and informational. The Pocket Radar allows you to quickly and easily determine the speed of objects or people, all by pointing at the object or person and clicking a big red button. About the size of a cell phone or a compact camera, the Pocket Radar is a nice gadget to throw in your bag, especially if your kids are in sports, or learning about physics. A few months ago I received a really cool and pretty useful gadget.
