MLD-100 laser distance meter questions

How far and how accurately does the MLD-100 measure?

The MLD-100 covers about 0.05 m to 100 m with typical accuracy around ±2 mm (plus a small distance-dependent term), suitable for most indoor and site dimensioning.

When should I choose the MLD-100 instead of the MLD-60?

Choose the MLD-100 when you need up to 100 m reach with multi-mode area/volume work; pick the MLD-60 for a more compact everyday meter when 60 m is enough.

Does the MLD-100 store previous measurements?

Yes — it can store about 30 records for quick recall on site, along with continuous and indirect (Pythagoras) modes.
