You mean "tens pads" ? ? ? We use them with the Fscan for spot on localized target contact zapping. You might check with your local medical supplies dealer. We were able to get tens pads (gel pads) at the local medical equipment supplier. Of course you will have to have the right cable (wires) to plug these into your zapper... the Fscan came with this optional tens pad cable (wires) and pads... In theory, it should work with any zapper.
