The Marsden M-560 is the UK's most popular slimming group scale, used by more slimming organisations across the country than any other model. With 250kg (39st) capacity, 0.5lb graduation and an imperial-only display that matches the stone-and-pounds format preferred by most UK slimming groups, the M-560 combines professional weighing accuracy with the practical portability and discreet remote indicator required for group weighing sessions. Three simultaneous displays show weight, height and BMI, with height entered via the full numeric keypad, giving slimming group leaders and personal trainers all three measurements from a single weighing episode.
Important: the M-560 is not Class III Approved under the NAWI Directive and is not intended for NHS clinical diagnostic use. For medically certified equivalents in metric units, the Class III Approved M-510 or M-545 are the appropriate clinical specifications.

The M-560 is designed for commercial weight management environments including slimming groups, fitness clubs, leisure centres and personal training studios, where imperial unit display and portability are the primary specification requirements and NAWI Directive Class III clinical certification is not required. The Tare function allows accessories such as clothing or bags to be removed from the weight reading, and the Hold function captures stable readings for active or restless individuals. The remote indicator supports group session privacy by allowing the weight reading to be positioned discreetly away from the member being weighed. For settings that require metric unit display alongside imperial, the M-565 provides both kg and st/lb options.
Why does the M-560 display weight in stone and pounds only, rather than kilograms?
The NAWI Directive, which governs Class III Approved clinical scales in the UK and EU, requires that approved medical scales display weight in metric units only (kilograms) for clinical diagnostic use. The M-560 is designed for slimming groups and fitness settings where imperial stone-and-pound display is the traditional and preferred format for members, rather than for clinical diagnostic purposes. Displaying in both imperial and metric would require NAWI Directive approval, which is why the Class III M-510 (the clinical equivalent of the M-560) displays only in metric. Slimming group members who prefer kg can use the M-565, which offers both unit options.
Is the M-560 accurate enough for meaningful weight tracking at slimming groups?
Yes. The M-560's 0.5lb graduation provides the accuracy needed for meaningful weekly weight change tracking in slimming group settings, where typical weekly changes range from 0.5lb to 3lb. The M-560 is based on the same weighing platform as the Class III Approved M-510, sharing the same internal weighing accuracy. The difference between the M-560 and M-510 is unit display and Class III certification, not the underlying measurement precision, making the M-560 a highly accurate scale for its intended commercial use despite not carrying clinical NAWI Directive approval.
