I am training a new guide dog and I want it, when crossing a road, to walk 
directly from one corner to the opposite one, so I would want a battery-powered 
device that emits a sound loud enough to be heard across the width of a 
two-lane highway.  Believe it or not!  (As Douglas Riddley used to say)  SH1 in 
the South Island is, for most of its length, only two lanes wide!

  Hi Jewel,
  Well, we designed one and the design is in the Smith-Kettlewell Technical file
  for all the good that does you unless you're into building electronics.
  it's called the "Little Go Beep"

  An engineer with the Handyhams folks, ham radio, designed a low power
  gizmo that sends a single character in morse code, either repeatedly
  or with a motion sensor. However this was to indicate locations on a marked
  trail, and intentionally not very loud.

  I asume you don't have power at your desired spot, that means either batteries
  or more expensive solar panel.

  Do you have reliable wind? if so a wind chime is simple.

  Try googling "sound beacon" and see if that helps, I'll do it also.

  Is this for a specific unchanging location, or do you want a pootable
  box you can put down so as to get back to where you put it?

  There are those gizmos for finding your keys when you clap your hands, but
  they're ment for indoors and I'll bet you're out wanderin about the pasture.

  Tom
