The wireless radar detectors are the detectors which are not using the wire or cable installation to power the device. It uses the batteries to power the unit. Some products provide you the chargeable feature that enables you to charge the exhausted battery pack. You will not need to purchase the completely new batteries once the batteries are drained.

When using these detectors, you will see that the devices turn on and off. The shut down period itself is about milliseconds. Because of the short period, you will hardly recognize that the devices actually switch on and off. This technique has the affect to the detector performance which is lowering the sensitivity of the wireless radar detectors.

The worst effect is experienced by the Ka band which has the wide frequencies range to scan. It also takes the power of the batteries in the quiet big amount to scan before compromising the duty cycles of the wireless. It can be said each detector which you choose will bring advantages and disadvantages. You need to trade the battery life for the sensitivity and the performance.

This device is lightweight and portable. Place the device in the most convenient spot in your car. Arranging your car will be easy since you will not be prevented by any cable or wiring installation.
