Survey Instruments are needed for the in-situ dynamic penetration tests and other purposes. These proffer info about the geotechnical engineering attributes of soil. Useful for several identification purposes, these are accessible with penetration resistance. The instruments have capacity to measure distances to any physical object, which has a light in color. Provided measuring instruments are highly useful for marking the orientation as well as sightings of stations. The navigation instruments, provided in the range are useful for ascertaining the heading of the crossbeam and angles.
