with lots of metal you should either try to get the metal
compensation module from polhemus or looking for another tracking
system (ascension's flock of bird for example). i've done
programming on both and must confess the bird is easier to use/
maintain but seems not that accurate at long distances as the
fastrak with a longranger does. you may contact me for some
sources but they are neither performer related nor performer tested.

hope this helps.
