Sonic cane

The sonic cane was a device used by the Eleventh Doctor to scan the Teselecta, and to contact Amy Pond and Rory Williams while they were miniaturised inside. Similar to the Eleventh Doctor's sonic screwdriver, the sonic cane emitted a green light, and featuews three "claws" which popped outwards to reveal the green light. It also recognised a signal from the sonic screwdriver. (DW: Let's Kill Hitler)
