Oops, never mind, thought it was a different model, I can't use it.

Thanks anyway.

I just bid on and won three Teledyne Geotech Helicorder's model RV-301B, for
which I am going to keep one and am willing to give the other two away. 
These units will require repair.  However, if you want one go to the EBay
listing for item # 6223171283 which closed yesterday select either one or
both of the two on the right side of your screen and let me know.  I will
inform the company to release it (them) to you.  You just have to pay
shipping which will run (in the USA) about $35.00 per unit.
