Your explanantion makes perfect sense as light intensity falls off with the inverse of the square of the distance.

Unless these things had amazing targeting and retargeting ie tracking. capability.

Since it uses the doppler effect could it be possible that they use a high intesity strobe opperating at teh same wavelength?

Do the tests show these thigns to be worthless and if so isn't that false advertising- a opening for lawsuits?
