Gunson 77038

Price: £35.98 Earth lead length: 150cm (minimum)

Circuit tester
Overall Auto Express rating

5.0

BEST BUY It’s the dearest, but is easily the most sophisticated. Included are advanced multimeter functions, such as impedance, capacitor and diode testing, duty cycle and frequency measurement, while the display holds the figure after the probe has been removed. The biggest letdown is that the unit is unable to power up components.
