The Stabila LD420 Laser Distance Measurer is for anyone working on sites or similar environments and requires a laser measurer that can do more than display distance. The LD420 features 13 functions and a high level of accuracy ensuring rapid results up to 80m. The large digits on the display make it easy to read. The memory can hold user defined constants (i.e. material costs in linear, area or volume). The LD420 can perform calculations on a measurement and display material requirements or job costs. The LD420 can store measurements and can call up additional information for many functions. The 13 functions include length, area, volume, continuous measurement, chain dimensions, Pythagoras with two and three measuring points, Pythagoras partial distance with three measuring points, minimum and maximum tracking, timer, stake-out and trapezoid. The LD420 has a high level of protection against water and dust and has an impact-resistant housing with shock-absorbing soft-grip casing. Supplied with two AAA batteries, belt pouch and wrist strap.
