A Plane Table consists of a smooth wooden table surface (with metal strengthening supports) mounted on a sturdy base. The base, a three-legged Tripod, is designed to support the table over a specific point on land. The connection between the tabletop and the adjustable Tripod legs permits the user to level the table precisely, using bubble levels in a horizontal plane regardless of the roughness of the terrain. The Plane Table is a surveying device used in surveying and mapping to provide a level surface on which to make drawings, charts or maps. An alidade, with or without a telescope located on the tabletop is used to sight features and draw angles to that feature. Using these lines to the same feature from different setup locations it is possible to locate that feature on the map. Plane Tabeling was widely used by the early members of the Australian Survey Corps and in both World Wars. It remains a simple and effective tool to teach the fundamentals of mapping and surveying. It was simple to use and was reasonably robust and portable. See also item 6489.2 for the Plane Table Alidade.A wooden Plane Table with alloy fittings to strengthen and support the table top.

This device was used to measure surface wind speed and direction. This anemometer was located on a concrete pad outside room 2.15 on a steel pole. The pole was considered unsafe and the anemometer was relocated to it's current position. When lowering the pole it fell over and was badly damaged. The Bureau of Meteorology donated it to the museum. It was then repaired and restored. The central pole on which it is mounted is galvanised iron pipe painted black. The anemometer, a portable device that manually measures wind speed, was a necessary instrument once common to all weather stations. The arms are attached to a vertical rod and as the wind blows, the cups rotate, making the rod spin. The stronger the wind blows, the faster the rod spins. The anemometer counts the number of rotations, or turns, which is used to calculate wind speed, surface wind and direction. They were designed to be durable to withstand the corrosive environment and strong winds expected at coastal sites such as those at Gabo Island. Anemometers existed in the nineteenth century and their design was improved by various experts including John Robinson in 1846, John Patterson in 1926, Brevoort and Joiner in 1935 and Derek Watson in 1991 who added wind direction measurement to its functions. This example was made for the Bureau of Meteorology by the Melbourne instrument company, Synchrotac, which became registered and incorporated on 26 July 1966. It is now displayed inside the building. A good example of its kind, the anemometer has first level contributory significance for its historic value and provenance to the lightstation.Anemometer and tripod stand.

The telescope is original to the Wilsons Promontory Lightstation and was provided by the Department of Shipping and Transport in about 1900. The device magnifies images of distant objects through its curved interior mirrors, and lightkeepers used this telescope to monitor and record the names of ships, the time they passed, and their direction, as well as read meanings of flags and other visual signals communicated by vessels. The telescope is similar to Cape Nelson’s two metre long telescope, which is included in the VHR registration for the Cape Nelson Lightstation. It is particularly important for its good condition, completeness and confirmed provenance and has first level contributory significance to the cultural heritage values of the lightstation..1 Brass telescope, cylindrical tube shape with mobile interfolding sections.

The Heliograph MkV is a fascinating piece of historical surveying and communications equipment. It was primarily used for visual signaling by reflecting sunlight with a mirror to send coded messages over long distances. This method was primarily useful in remote areas where other forms of communication were not available. The MkV model, specifically, was widely used by the British Army and other military forces from around 1906 until the mid 1960s. It remained in use with the Australian Army Survey Corps until the mid 1980s. The device typically included a 5 - inch mirror and was often mounted on a tripod for stability. Initially the instrument was used to communicate between survey stations using Morse code to coordinate their activities. Later when better forms of communication were available, they were used for precise angle alignment where the sunlight reflection from the mirror was targeted between the survey stations to give very accurate results. The MkV was relatively light weight and portable, making it ideal for use in the field. It could be setup and adjusted quickly. The heliograph had an adjustable mirror that could be tilted to reflect sunlight towards a distant receiver. Surveyors could align the mirror using a sighting device. Whilst it was primarily used by the Military it was also used in civil surveying particularly in the remote areas of Australia. The British Army Mark V version uses a flat round mirror with a small unsilvered spot in the centre. The sender aligned the heliograph to the target by looking at the reflected target in the mirror and moving their head until the target was hidden by the unsilvered spot. Keeping their head still, they then adjusted the aiming rod so its cross wires bisected the target, they then turned up the sighting vane, which covered the cross wires with a diagram of a cross, and aligned the mirror with the tangent and elevation screws, so the small shadow that was a reflection of the unsilvered spot hole was on the cross target. This indicated that the sunbeam was pointing at the target. If the sun was in front of the sender, its rays were reflected directly from this mirror to the receiving station. If the sun was behind the sender, the sighting rod was replaced by a second mirror, to capture the sunlight and direct it onto the main mirror to reflect it to the receiving station.. 1 Brish Army "Mance" Mk V A253 Heliograph has two 125mm diameter mirrors on a brass arm with targeting attachments.
