The current 81mm mortars used by the SANDF are too heavy for some missions, according to defpro.com.
The LH41C, also known as the Acrobat, is incorporated with a personnel digital assistant (PDA) fitted with GPS, used to calculate target coordinates and fall-of-shot corrections.
The system comprises the M6 60mm long-range mortar with its suite of ammunition, fire control computer and observation system.
Carl Zeiss Optronics managing director Kobus Viljoen said the LH-41C laser rangefinder was easy to use and compact in size, providing long-range performance.
The units are scheduled to be delivered in November 2010.
