From the characteristics of the new (1976) electronic components and units that are being marketed, the author has tried to foresee the types and the performances of the near-future slope-monitoring equipment. Much-improved sensors, instruments and systems for pit use can now be developed — sun-powered telemetry remote stations are feasible, very sensitive as well as precise and drift-free liquid level inclinometers will be available, new techniques for distance measurement with lasers obviate the need for atmospheric corrections and the latest generation of desktop calculators have become easily programmed minicomputers. Thus, it is realistic to assume that fully automatic pit-slope monitoring systems will be operational in the foreseeable future.
