Walk into any electrical wholesaler and you'll see them hanging near the till. Credit card sized. Gold contacts. Around twenty quid. The CalCard. Some sparks swear by them. Keep one in their wallet, test their MFT monthly, log the results religiously. Others reckon they're pointless if you're getting annual calibration anyway. A few have bought one, used it twice, and it's been gathering dust in a toolbox ever since.
