If you’re constantly worried about your friends, family, boss, co-workers or even internal affairs setting you up then carrying around this audio recording device blocker 24/7 might be a good idea. It emits a sub-audible tone which cannot be detected by the human ear but will end up drowning out any audio recordings when played back.
The built-in rechargeable batteries will last for about 2.5 hours which is a bit limited for those that are truly paranoid but the unit can also be plugged in. For digital recorders it has an effective range of about 0.5 to 2 meters but for tape recorders that range is increased to about 3 to 8 meters. It also includes a remote control that can be used to switch the blocker on and off since you’re no doubt going to want to be discrete about using it.
The Tape Recorder Blocker is available from Spycatcher for about $3,800 which isn’t cheap but I guess if it helps keep you out of prison it’s probably worth it.
