This item was most probably used at the Ballarat School of Mines. Pajari Instruments Ltd. grew from a partnership established in 1945 when the first EX-AX surveying instrument that provided accurate azimuth and inclination was made available to the diamond drilling industry. The partnership between Charles Trotter and George Pajari Sr. was known as Trotter-Pajari Instruments and the EX-AX Instrument was dubbed the "TROPARI" by the diamond drilling industry. Charles Trotter, a mechanical engineer, was also a marketing genius who developed substantial demand in Australia, Africa and South America in the 1940's and early 1950's. In fact the sales to each of these continents exceeded those to North America during those early years. Pajari is located in Orillia, Ontario, Canada and offer services and products that assist customers with their individual requirements. After the death of Charles Trotter in 1956, George Pajari Sr. with the assistance of his wife Hilda continued the business under the title of Pajari Instruments. George Sr. set most of the tenets that comprise our present Mission Statement. If it wasn't user friendly or if it had to have experts to operate it, that instrument design was doomed. If the customer wasn't getting good value in his opinion, manufacturing and repair procedures were examined to see where efficiency could be improved to cut costs without sacrificing Quality. George Pajari Jr and his wife Darlene assumed the reins of Pajari Instruments Ltd. in 1981 when George Sr. decided on semi-retirement. George Jr. brought the "client geologist's" perspective to the company. The company moved from Toronto to a 30 hectare (80 acre) site near Orillia shortly afterward. This site provided the high magnetic latitude earth field environment without magnetic pollution that is necessary for accurate compass setting. The park like setting of this location is a positive psychological benefit for our staff. George Sr. passed away in 2002 being preceded by Hilda only by 3 months, George Jr. continues at the helm of the company. With dedication from long term employees/contractors and third generation family members, Pajari Instruments Ltd. continues operations/new product development in Orillia.

Known as a Tropari - a single-shot, micro-mechanical borehole surveying instrument operated by a timing device. Borehole direction is measured from the earth's magnetic field. The Tropari provides both direction and inclination which can be used to define the attitude of the borehole at the survey depth. Regular surveys at intervals as the borehole progresses will allow a plot of the borehole to be drawn from the data. The Tropari is easy to use and maximizes profits by minimizing capital and operational costs. The Basic Survey Train Consists of: PDSI / Tropari Container, 6m (20 ft) Nonmagnetic Rods, Impact Foot, and Connector at Top.
