Will SR Measure work for stockpiles in bins and bunkers?

Is there a pile size or shape limitation?

The SR Measure app does not have restrictions on pile size or shape.

How repeatable are the measurement results?

Measurements in the app are highly repeatable because of the precision of our proprietary algorithms.

The SR Measure app determines the toe using a consistent process for scoring stockpile risks and attributes, ensuring consistency between measurements.
