Are you going to be in the "bath tub" (old style units)? If so I hope the water is warm. 
Nope - no diapers!!
The reason why they could not use the older style unit (they have a new and older one) on me is that the stone is quite small - 2mm x 4mm, and the older machine (which also does not use the tub) could not see it.
