electrical safety

As any electrician knows, it’s very straightforward to trace cables… providing you can see them. As soon as they’re buried in walls or under floor spaces, finding cables becomes a laborious combination of educated guesswork, luck and dogged persistence, aided by an insight into whatever was going on in the crazed mind of the person who installed them in such a bizarre topology.

Cable finders such as the Martindale CD1000 and CEM CLS20 claim to put an end to all your cable-finding problems. But do they deliver all they promise? And which should you spend your money on: the CLS20 (currently £119 + VAT), or the CD1000 (£259 + VAT)?
