The analogy seems obvious enough to me the beam can only be transmitted at
a
specified power (laser can burn the retina of the target/victim, microwave
radar can cause cataracts) and a Mitsubishi Zero can only so far on the
fuel
it can carry - in both cases each can only travel a certain distance. The
Zero can hit a target twice as far away if it doesn't need fuel reserve to
make the return trip, and a speed gun beam is detectable at twice the
trapping distance because the beam to target and back again can only cover
half the distance that the straight one way path of the beam from gun to a
detector on the target still carries enough energy to be detected.

Once again I can draw pictures for you if you move to a binaries.

What you fail to take into account however, is that the laser beam is
*not switched on* until the vehicle is within range and the operator
wants to take a speed measurement. So it will not be detected at
twice the measurement range at all, because at that range there is no
operating laser to detect.

I can draw you a cartoon of that if you move to binaries.

I get the picture - and I didn't know that.

It seems strange that companies can get away with selling detectors that
obviously won't work - unless the laser is activated to check the speed of
traffic 1/4 of a mile ahead of you.

No doubt its also possible to get caught out using satnav Gatso maps if your
unit hasn't been updated to a new camera.
