The correct approach to locating most illegal telephone taps involves the use of visual inspection and basic tools, such as a screwdriver and a butt set. This method is practical and allows an investigator to physically check the wiring and connections for any unauthorized modifications or devices. A visual inspection can reveal signs of tampering or the presence of hidden recording devices, especially in accessible areas like phone boxes and junction points.

The use of a butt set, a type of telephone test set, is particularly effective because it allows an investigator to listen in on the line's transmission without directly connecting to a phone. This can help identify unusual electrical signals or patterns that suggest the presence of a tap.

Other methods such as hiring a specialist or using advanced software may not be immediately effective in all situations, especially considering the practical, hands-on nature of identifying unauthorized devices that may be physically present. Additionally, wire tracing techniques might also require specialized knowledge or equipment that may not be necessary for a straightforward, visual approach.
