A lawmower or goat perhaps? >> Surely the easyest way to locate either of the above is to sample a sound from them and then using a Kunstkoph (read head with two mics in it) check the time devation between the ears, using two spaced a couple of meters apart not only could you tell x&y but also z this may be important when trying to determine that the Goat has climbed the rockery. Defensive steps could then be taken with the lawn cutting lazer to cut the Goat off at the knees thus preventing terminal damage to ones prize roses................ The Goat saga continues.........
