As far as I know this gadget was never officialy sold. But you probably can get it in a Hilti Center (you can find the address of a Hilti Center in your area on www.hilti.com).

I heared that this "tool" will be produced to be sold regularely next year (I do not know a specific date). Unfurtunately I cannot say if it will be sold worldwide (in each of the 120 Hilti market organisations) or just in some special one. I hope to remember your request when I get more informations and post it.
