Our Research Methodology

We surveyed a wide range of RF bug detectors. The main criteria we selected for choosing our top pick are frequency range, accuracy, ease of use, cost, and battery life.

Frequency Range

A cellphone is detected by the virtue of its emitted frequency. Consider that a phone operates at a range of different frequencies. To find a mobile phone, the detector must be able to pick up a wide range of frequencies.

Accuracy

The accuracy of the RF detector is dependent upon its sensitivity and dynamic range of the electronics. A good RF detector must be able to detect the faintest signal being emitted amidst strong ones.

Ease of use

Ease of use, and portability is one of the key points for the selection of any RF detector. The user must be able to easily use the instrument.

Cost

Cost is a big one obviously and it determines accessibility.

Battery life
