Proton magnetometer or magnetometer GSM-19T, manufactured by GEM, is currently the best-selling and most accurate proton magnetometer in the world. The Canadian company GEM has been a leader in the supply of new magnetometric technologies in various sensitivities since 1980 and has been producing a complete series of magnetometers, gradients and VLFs. In surface surveys, proton magnetometers are usually the most widely used, and unlike Fluxgate, this type only has the ability to measure the Earth's magnetic field strongly, which is very simple and fast to measure. This type of measurement is called general field measurement. The sensitive part of this magnetometer is a cylinder that is filled with a liquid saturated with hydrogen atoms and surrounded by a coil. The liquid inside the cylinder contains parts such as water, oil and alcohol. The magnitude of the magnetic field that this device can show is 0.05 nanocells. This device also has no noticeable error over time. One of the most important advantages of precession magnetometers is simplicity and high reliability. The device can be used by one person alone and very accurate magnetometric surveys can be performed with this device up to 10 hectares per day. GEM magnetometer model GSM-19T is currently the best-selling magnetometer in Iran, which is widely used in mine exploration projects, especially iron mines.
