Re: ss frame and metal detectors

["Gary Gill" <garyg@xxxx>]

FWIW

For a loop of wire to "detect" metal, there must be motion.
It is the car passing over/into the loop which generates a current in 
the wire. This current is then sensed. Hence, it doesn't matter 
where the bike stops. If it has enough metal to generate the 
required current to set off the sensors, it will do so when the bike 
enters the loop.
