electronic calipers

Electronic calipers, the digital precision tools your toolbox didn't know it desperately needed, offer accuracy to 0.01 mm with an easy-to-read digital display. They measure internal, external, depth, and step dimensions faster than you can say 'micrometer'. New models usually retail between $30 to $150 AUD, while used ones can be found on Tradingpost or CarShowroom for less if you're into second-hand thrills. Beware the usual issues like battery drainage, display malfunctions, and occasional calibration slip-ups, which make your measurements as reliable as a politician's promises.

• Battery life can be frustratingly short.
• Digital screens may become unreadable over time.
• Calibration can drift, causing inaccurate readings.
