The effective distance of a handheld speedometer varies depending on factors such as the type and performance of the instrument and the characteristics of the object being detected.

Laser speedometer

Generally speaking, the effective distance of a laser handheld speedometer is longer. Its effective measurement distance is usually between a few hundred meters and a few thousand meters. For example, some high-quality laser speedometers for traffic use have an effective distance of about 300-800 meters. This is because the laser has the characteristics of strong directionality and concentrated energy, and can accurately measure the speed of the target object at a long distance. However, its effective distance will also be affected by weather conditions, such as in rain, fog, dust and other weather conditions, the effective distance will be shortened. Because these weather conditions can cause the laser to scatter and attenuate, reducing the signal strength reflected back to the speedometer.

Radar speedometer

The effective distance of a handheld radar speedometer is relatively short. Usually in the range of tens of meters to hundreds of meters. The common effective distance is about 10-300 meters. Its working principle is to measure speed by emitting radar waves and receiving reflected waves. The propagation of radar waves will be disturbed by the surrounding environment, and its beam angle is relatively wide. As the distance increases, the range of the beam coverage will be larger, and it is easily disturbed by the reflected waves of other objects, so the effective distance is not as far as the laser speed meter. In addition, the effective distance of radar speed meters in different frequency bands is also different. For example, the effective distance of radar speed meters in lower frequency bands may be relatively short, while those in higher frequency bands may be slightly longer, but at the same time, those in higher frequency bands are also more susceptible to environmental factors.

Ultrasonic speed meter

The effective distance of handheld ultrasonic speed meters is usually short, mostly within 10 meters. Ultrasonic waves attenuate energy faster when propagating in the air, and their propagation speed is slower than that of laser and radar waves. This makes it have serious signal loss when measuring at long distances, so it is mainly used for close-range speed measurement, such as in some small, short-range experimental devices or close-range industrial process monitoring.
