Who and what is the 3185 designed for ?
The David White 3185 is a motor driven, electronic self-leveling single grade laser designed drainage and civil earthworks applications. With its 850m operating range and accuracy of 1.5mm per 30m (10” sec arc), it is well suited to long range contracting applications.
The David White 3185 features a single grade range of -10% to +15% with a clear LCD Display. When the single grade is entered, e.g. 2.25%, the laser self levels at the desired slope while still maintaining cross axis leveling at the same time.
Grade increments are 0.01% from 0 to 2.5%, 0.05% increments from 2.5 to 15%
