The Safe Line 100 Telephone Analyzer offers six levels of protection for your telephone line security. The thing is a veritable Rottweiler, it will detect changes in your line voltage, deactivates all known wire tapping devices, shifts frequenies, defeats voice activated kit by generating noise, and instantly alerts you if anyone is trying to eavesdrop covertly. $199.95 for total paranoia free peace of mind.
But what about those pesky, high tech crystal controlled parallel line transmitters? Useless… The phone line analyzer will simply shift their frequency and they will transmit nothing but static. Even the feared VOX, voice activated, systems are putty in the hands of the phone line analyzer. The Safe Line 100 Anti-Vox systems are neutralized so that the money and effort put into installing these devices by your adversary are futile.
