How Accurate is the Pocket Radar? Does it Need to Be Calibrated?

Modified on April 12th, 2024

Pocket radar devices have become invaluable tools for sports enthusiasts, athletes, and coaches. However, ensuring the accuracy of these devices is crucial for obtaining reliable data.

How Accurate is The Pocket Radar Gun?

According to the manufacturer’s website, Pocket Radar technology provides +/- 1 MPH accuracy and has been certified for accuracy by the same test lab that certifies all police radar equipment1. Reviews from users and experts generally support this claim, with many stating that the Pocket Radar Ball Coach is accurate and consistent within 1mph of other readings. However, some users have noted that the accuracy can be affected if the radar is not pointed directly at the target.

What factors can affect the accuracy of the pocket radar?

Positioning off to the side of the target can negatively impact the accuracy of the Pocket Radar. It’s not designed to work at angles, and if it is placed more than a few feet to the left or right of the direct ball path, it may result in lower speed readings. Environmental conditions, such as extreme temperatures, humidity, and wind, can impact the accuracy of your pocket radar device. Be aware of these factors and adjust your usage accordingly to maintain accurate readings.

How to calibrate a Pocket Radar?

According to the Pocket Radar, their products are very stable and hold the factory calibration, so they do not need any further calibration. If you have repeat issues, reach out to the company directly.

Ensuring Optimal Device Performance

Radar guns, including the Pocket Radar, measure the relative speed of an object moving directly towards or away from the antenna. If pointed at an object moving sideways, the radar will display a slower, inaccurate speed due to the object’s minimal relative speed towards or away from the radar. To obtain the most accurate speed measurement, align the Pocket Radar antenna with the object’s direction of motion. However, always prioritize safety—never put yourself or others in a position where there’s a risk of being hit by the moving object.

Verifying the Accuracy of Your Pocket Radar Device

Comparing with Known Accurate Tools

To verify the accuracy of your pocket radar device, compare its readings with a known accurate speed measurement tool, such as a professionally calibrated radar gun or a speed measurement device used by law enforcement.

Troubleshooting Discrepancies in Readings

If discrepancies are observed between your pocket radar device and a known accurate tool, consult your device’s user manual or contact the manufacturer for assistance. They may offer guidance on calibration, maintenance, or repairs if necessary.
