Usage guide

Typical uses: transferring levels from benchmarks, setting foundation, floor and slab levels, slopes, drainage networks and roads, and longitudinal and cross-section levelling.

Before you buy: check the magnification and the accuracy per kilometre, and pair the level with a suitable tripod and a staff long enough for the height differences on your site, plus a staff bubble to keep it vertical. You can order a complete kit (level, tripod and staff) from EL EMAN.
