A word of caution

There are literally hundreds of vendors offering "bug sweeps" on the internet and business  yellow pages.

The vast majority are using eBay bug detectors or equipment designed in the 70s to find analog bugs.

RTSA/DPX depicted below is utilized to find today's threats. Covert transmissions hidden within other radio signals.

This cutting edge technology is used by fewer than 2% of Private TSCM firms.
