 Why had the owners of Little Probe obtained the E.P. Locator at such a discounted rate?
[Transcriber's Note: This etext was produced from Worlds of If Science Fiction, March 1961. But this might be so varied or so unfamiliar that often both the machine and the designer of it were puzzled as to how to read the results. The E. P. Locator had been designed by Glaser. But when the Locator had refused to read Positive when turned on the inventor himself, bad blood developed between machine and man. And it was for this reason also that the owners of Little Probe had acquired the original machine so cheaply. And there was no denying that the Extraordinary Perception Locator (or Eppel) was a contrary machine. Yet on Suzuki-Mi it had read Positive on a two-inch-long worm, only one of them out of billions.
 The designer had no longer used it as it had not detected E.P. on himself.
 The readings were unclear as it had struggled with detecting E.P on worms.  The designer had no longer used it as it had not detected E.P. on himself.  It was a faulty machine and often shut off without notice.  It often produced an orange light meaning it was unsure of the results.
