Want to hear the magnetic fields you encounter in stereo? Strap on a pair of these amplified coils and its like being able to hear the invisible fields. Simple single axis magnetic pick-up coils with built-in audio amplifiers translate the frequency of the magnetic field to the same pitch of audio tone. You can easily distinguish the drone of 60 Hz, as well as identify other frequencies when present such as you would find near LED lights, TVs, dimmer switches and so on. And the sensitivity is such that the sound is louder in the ear nearest the field giving a realistic sensation of hearing the field, making it extremely useful for locating sources of the disturbance. A pair of devices, each with a AA battery is included. Use your own headband, earphones, hands, or just about any hat which covers your ears to hold them in place. Of course, they can be used to amplify the sound of a telephone earpiece as well. (Part. #GIVa123) EMF Headset (Part. #GIVA123) $22.95 a123

	E.L.F.-ZONE GAUSS METER Identifies Safe Distance From Radiation Source What this meter lacks in resolution it makes up with ease of use and very low cost. Will measure ELF/VLF magnetic fields in the frequency range of 20 - 10,000 Hz, with a minimum sensitivity of .25 mG. Laboratory tested and documented for accuracy. Three LED lights signal field strength: 0 - 2.5 mG ("safe") 2.5 - 7 mG ("caution") 8 or more mG ("danger") Single axis sensor, on/off toggle switch, and 9V battery included. Useful for preliminary surveys of home, car, or office. Very popular for paranormal work too! E.L.F.-Zone Gaussmeter (Cat. #A121) E.L.F. Meter (Part. #GIVA121) $17.95 A121

	A Yellow Light will stay illuminated if a transmitter has not been detected. The Orange Light will illuminate when the +Plus Guard detects weak radio waves from an RF transmitter. The Red Light will illuminate within a few feet of the transmitter, then flash along with a low audio alarm within a few inches of the transmitter as the signal gets stronger! The unit can be used as is, plus two external antennas are provided for extended sensitivity. Tuned to be especially sensitive at 460 MHz, 900 MHz, and 2.4 GHz which are common bugging frequencies, but it will respond to a much wider range. No further frequency/response or sensitivity data is available. 90 day mfr. warranty. Made in USA. +Plus Guard (Cat. GIVA122)        $49.95  Plus Guard(Cat GIVA122) $49.95 GIVA122

	MicroAlert will respond to as little as 0.1 µW/cm² in highest sensitivity mode. When MicroAlert is moved closer to the source of RF radiation, the chirps will become more frequent, and will become a solid tone when exposure is high. Responds to frequencies from 500 kHz to 3 GHz, although response is not flat over this range. What this means is that at any given setting, the threshold will vary with frequency. Note: This is not a high precision meter. Sensitivity information is only a guideline. The beeping alarm threshold can be adjusted from no threshold (constant beeping regardless of radiation exposure), to to a maximum of about 10 microWatts/cm². It is intended to be an alarm for cell phones, cell towers, microwave ovens, surveillance bugs, and most RF transmitters. Only 1-5/8" x 2-1/4", the 1 oz. MicroAlert uses one Lithium coin cell #2032 which should last about 3 years with normal use. Includes convenient belt clip. 1 year mfr. warrantee.

	Pocket Sized E-Field Detector Not a toy but a real Electric Field detector! Features include LED indicator light, audible intensity signal, rotary on/off switch, and pocket clip. Does not give you a numerical readout, but it will tell you if high E-fields are present or not. Red LED lights when field is detected and audible tone gives indication of field strength and frequency. Useful for detecting and tracing live wires (50/60 Hz, 100-600v) and comparing safe distances from similar appliances. Rotary switch permits adjustment of sensitivity. Requires 2 AA batteries.  Use the ELFLX to: locate live electrical wires inside or behind plaster, drywall, wood, paper, plastic, etc. detect a break in an electric circuit (Christmas lights, extension cords) check wires, fencing, appliances, fuses to see if they are energized remotely check high voltage power lines check spark plugs and distributor wires of operating automobile engines locate sources of electric fields (such as lamp cords, clocks, electric blankets) which may pose health problems if too close to people and animals ELFLX Detector (Cat. #GIVA195)...$9.95 GIVA195
