The circular shaft and metallic adjuster are noticeable differences between this and the Laser 3837, but it is arguably a better buy. Its impressive 1.25% average error is only half the story – the average error when set at 100% was 0.04%. It falls short, though, with its scales. Besides the more familiar Nm, there is the kg.m scale which is marked out in odd decimalised intervals. Despite this, the 3995 is a good tool overall.
