The Martindale FD650 digital fuse finder kit allows for tracing of fuses through mains sockets, light fittings and points in a circuit where there is no power socket available.

The transmitter is supplied with a mains plug and a set of two wire test leads, emitting a signal for the receiver to pick up. The microprocessor controlled multi-level sensitivity makes identification of fuses and breakers much easier. The Elite fuse finder also features a non-contact voltage indicator.

The FD650 fuse finder is supplied in a hard carry case with a transmitter, mains plug, two wire test leads, receiver, batteries and instruction manual.
