Overall score 18/20 Comments Coming in at less than £50, this is an incredibly comprehensive piece of equipment. It tests temperature, frequency, dwell, RPM, and diodes. An induction pick-up means that the RPM function can be used with all engines, regardless of number of cylinders.

Comments A serious piece of kit suited to diagnostic professionals. This does all the things that our 'Best Buy' can, and more. One of its most useful functions is averaging, which monitors fluctuating readings and provides minimum, maximum, and mean values.

Comments Draper's smaller meter is still incredibly competent. Thanks to the inductive pick-up, the RPM function works on all engines regardless of the number of cylinders. Dwell, as before, is possible only on 3-, 4-, 5-, 6-, and 8-cylinder motors.

Comments This does less than the 'recommended' Draper, but is nicer to use. There is no frequency-measuring function, and the lack of inductive pick-up means that both the RPM and dwell are restricted to 4-, 6-, and 8-cylinder motors.

Comments The basic Draper juts misses out on being the 'Best Budget Buy', because £25 is the cut-off point. But, even at this bargain price, it is still a comprehensive unit.

Comments As the highest scoring meter under the £25 barrier, this is the obvious 'Best Budget Buy'. In terms of what it can do, it's very similar to Draper's 50024. As well as the usual Volts, Amps, resistance, continuity, and diode checks, it can also show dwell and revs on 3-, 4-, 5-, 6- and 8-cylinder engines.

Comments There is a strange mixture of features on this meter. It is probably best suited to general electronics than automotive usage. Apart from the standard Volts, Amps, Ohms, diode check, temperature measurement, and audible continuity test,

Comments Many of the comments levelled at Laser's meter can also be applied here, as well. Granted, there are lots of parts of a motorhome where testing volts, amps, resistance, diodes, and continuity are useful.

Comments At a smidgen over a tenner, there are two ways of looking at this meter. As an accurate way of testing Volts, Amperage, resistance, diodes, and electrical continuity, it is fantastic value.

Overall score 4/20
Comments At this price, it is hard to imagine just who would actually go out and buy this meter, since it has very few advantages over Gunson's own Pocketmeter 2 or even their excellent meter 105. Granted, the display is somewhat bigger than Pocketmeter 2's. But other than the usual multimeter functions, this has no useful automotive functions. Worse still, the body has no stand, no protective cover, and no crocodile clips. l–
