Combine the dislocator and the block detector to get the best of both! This block will break anything thats in front of it, as long as it matches what is inside of it. And of course, and places whatever it breaks in the inventory behind it :D
Right click it to open the interface that looks exactly like the Block Detector one. Put whatever you want in there and as soon as it detects that around it, For example use it to automatically break sugarcane when its grown.
