Dear Colleagues,

We seek to purchase or trade for a used (inexpensive) Polhemus
12 (or 8 or 4) sensor electromagnetic motion capture system such as
the Liberty 240 Hz model.

If you possess any information regarding the possibility of locating
someone who wishes to sell, even if you might not own the device
yourself, I would be grateful to hear from you.

Thank you.

best regards,
Dr. Paul Treffner
