Historical evolution meets modern technology

es-50_topconA newly designed, rugged, and waterproof optical total station with the convenience of also measuring reflectorless to any surface, the ES-50 incorporates all time-honored expectations and more.

Available in either a 2 or 5 arc second accuracy, the ES-50 is ideal for land surveying, topography, construction layout, foundation and exterior job sites, as well as as-built projects.

Proceed as planned knowing that each compact and rechargeable battery delivers up to 15 hours or projects site productivity. Proven dual axis compensators get it right the first time, while a tight waterproof design let’s you rest easy during unexpected weather changes.

For Interior or exterior construction layout projects, a bright laser pointer vividly shines to precisely denote where your next digital design will be-visualize and check for problems before they become problems.

With an eye on safety, the unit has a smaller beam width then other non-prism instruments in this class, resulting in non-prism measurements out to 350 m.
