Used by law enforcement and private investigators,   this Counter surveillance Probe/Monitor provides five of the "most desired sweep functions" in one package. 
1. R.F. probe "sniffs" your environment for hidden phone, room or body bugs, remote signals, computer, Fax or Telex
transmitters, video transmitters, pulsed tracking transmitters, and even wide band frequency hopping or "burst" bugs.
2. V.L.F. probe tests your A.C. outlets, phone lines
or suspicious wires for very low frequency "carrier 
current" signs.
3. Auxiliary audio input allows you to listen to
telephones or lines for "hotmikes," hookswitch by-pass 
and "infinity" bugs, also unknown wires and
cables can be tested for wired microphones.
4. After a sweep, the alarm monitor guards against new
devices brought in, remote control activation, or someone tamper-ing with your equipment.
5. The 24-hour "evidence" recording output will store suspicious sounds on a standard cassette recorder while you are away.
DETECT AND LOCATE quickly and silently all major categories of electronic surveillance, including:  Room, phone,
and body bugs that are transmitting your conversations  Video transmitters watching your every move  Vehicle tracking
beepers giving away your location  Infinity bugs, hook switch bypass or reversals "turned-on" to your conversations
 Wired microphones listening inside a wall  Computer, Fax or Telex transmitters "reading" your information  Tempest
leakage.
*Even at high security levels where a spectrum analyzer may be employed, the CPM is an invaluable tool
for detecting ultra-sophisticated frequency hopping or "burst" bugs.
THE ALARM MONITOR MODE protects you after a sweep by continuously checking for: New devices brought in
 Remote control activation  Nearby two-way communications  Phone line tampering.
RECORD ON TAP while you are away, storing evidence on:  Sounds of an eavesdropper installing a bug or tap
 Noises of an intruder "snooping" in your office  Unauthorized usage of your equipment.
