The PSC-1003 is the first and only telephone line security device that can detect electronically isolated remote extension drawn loops; the most sophisticated, threatening and common type of electronic surveillance that other security devices cannot detect. Detect eavesdropping/wiretapping that previously had been undetectable.

This is the only security device that can detect legal and illegal wiretapping anywhere on the local telephone line including at the Telephone Company's Central Exchange.

Detect wiretaps the Telephone Company cannot or will not acknowledge. Detect wiretapping professionals that even your Telephone Company cannot find.

Continuously protects your Telephone, Fax and Computer Data communications "to a degree never before possible."

Ideal for anyone who feels that their phone line is being tapped. This will detect virtually all phone tapping devices on the market today.
