| The Checkmate range offers a low-cost, reliable and consistent method of bug-detecting. The units are high-quality hand-held detectors; the latest in electronic design and ergonomic styling. CHECKMATE 1 Checkmate 1 is an inexpensive but highly sensitive unit. It can detect all types of room and telephone transmitters by means of an LED bar graph display. CHECKMATE 2 Checkmate 2 offers a higher sensitivity and wider frequency response. It shares the LED panel of Checkmate 1 but has the additional feature of an audio indicator allowing you a second method of locating a transmitter. CHECKMATE 3 Checkmate 3 is the most advanced model of the Checkmate range. Developed with even higher sensitivity than 1 or 2, it is expertly designed to perform to the highest standards. Checkmate 3 has additional connectors allowing you to use headphones for more discreet operations, and to connect a telephone test lead directly to the line to detect telephone transmitters. As well as LED and audio indicators, Checkmate 3 features the innovation of a "verify" mode; it can confirm the presence of a transmitter by partly demodulating the signal |
