TESLA 4 channel groundwater detector is designed on a frequency amplification sequence working on magnetotellurics 4 channel detection method. The system is powered for deeper depth penetration and noise reduction by utilizing the effect of different channels in order to decrease the noise data's which may affect the actual results in a groundwater survey. The system is powered to penetrate and capture data's to a depth of 400 meters in favorable geological conditions, power consumption of 0-5000 mv is inbuilt with an auto amplifier to support in cases where the penetration possibilities are poor and thus our equipment is ideal to suit any geological terrain in assessment of field data's.
