However, for Disto surveying, it feels largely unnecessary, as the accuracy is already a lot more than most surveys need when just using forward sightings.

But because DistoX is an electronic device it is only way to be sure it works properly. The same as check, if three (four) readings for surveying leg with rotation around the longitudinal axe of DistoX are in tolerance interval. Martin S.
