Page 25 of Flying Saucers Magazine - February 1961

While traveling in different areas I have made several experimental flying saucer detectors and have some good reports of results. One especially made by Jim Hendrix, 5449, Morris Avenue, St. Joseph, Missouri, who told me of several sightings as a result of the detector sounding off. Of most interest to me was his report showing the apparent sensitivity of the gadget. He tells of his going outside at his place of employment and scanning the skies. He saw what appeared to be a UFO above a high broken overcast. At the same time Mrs. Hendrix who was at home several miles away, was alerted by the detector.

Whenever I mention this detector at my lectures, keen interest is shown by flying saucer enthusiasts and plans are immediately requested. As this simple device seems effective, I would like to pass it on to others. Therefore I am submitting the enclosed information to you in case you may see fit to publish it.

The detector unit consists of a 6 volt door bell or buzzer, a 6 volt lantern battery and a permanent magnet hanging on a length of thin copper wire with at least a 30 inch swing, and passing through a 3/16 inch loop which acts as a switch to close the circuit. A longer swing tends to increase the sensitivity of the detector, but it also makes it more sensitive to drafts.

This detector can be hung from the ceiling or a shelf as a permanent fixture, or can be mounted on an upright board as a portable unit. This portable unit is shown in the photo which has both front and side views.

A good magnet for this unit is manufactured by R. J. R. Toy Co. This is a round disk ceramic magnet and is sold by many toy stores 3 on a card. It is also handled by many Western Auto Supply Stores (I use 2 of these disks on the detector) Most large hardware stores handle magnets, and another good source is in cast-off radio loud speakers. The permanent magnet type can be detected without dismanteling by holding a knife blade close to the back coil or the old speaker.
