Ohm decade box
Works very well for diagnosis of wires in automobiles. I have used it for diagnisis of airbag wire, coolant temp sensor etc.

Often when calibrating a multimeter I need known resistances from 1 Ohm to 10 M Ohm and this provides an excellent fit for that requirement . It saves hours of faffing around measuring and sorting 1% resistors trying to get 6 digits of precision when the heat from your fingers can move the resistance by hundreds of counts. I use a 7.5 digit meter and set the required resistance using this box in a few seconds. It’s a real time saver and the accuracy of the resistances is closer to .1% than 1% which makes things easier.
