HANMATEK Laser distance meter, 100 m (328 ft) vs Bosch Professional Laser distance meter, site-rated

Published accuracy, or a body that survives the bag?

These two are the clearest illustration of what this site is about. The cheaper meter publishes ± 1.5 mm (0.06 in) and a 100 m (328 ft) range; the dearer one publishes IP 65 and a 1.5 m (5 ft) drop onto concrete, and no accuracy at all.

A tick marks the better answer on that line only. Counting ticks does not decide the page — the two verdicts below do, because these products answer different questions.

Which of the two, for which tolerance

Buy the HANMATEK Laser distance meter, 100 m (328 ft)

Prefer the HANMATEK if the meter lives indoors and the number matters. It publishes the tightest accuracy in the whole hub and reaches two and a half times further, for roughly half the price.

Bosch Professional Laser distance meter, site-rated

No amazon.com listing was found for this one. We hold references for other markets but none for the United States, so it may not be buyable here — which is the first thing to weigh against anything below.

Buy the Bosch Professional if the meter shares a bag with hammers. IP 65 and a 1.5 m (5 ft) drop rating are what keep it a meter next year — and read the specification sheet in the box for the accuracy figure the listing omits.

What gets asked here

Why does Bosch Professional not publish an accuracy?

We do not know, and we will not print a figure we cannot source. The listing states IP 65, a 1.5 m (5 ft) drop, seven modes and a color display. The accuracy is in the specification sheet supplied with the tool, and it is the first thing to read when it arrives.

Is IP54 enough for a building site?

It covers dust and splashing water, which is enough for interior work and marginal outdoors. IP 65 is dust-tight and resists water jets, which is a different class of protection.
