Electromagnetic Geonics EM-34 XL

Geonics EM-34 XL

Item # 101120

Included Accessories: Transmitter, Receiver, (2) coils, (3) cables - 10m,20m,40m

The EM34-3 is a fast, simple to operate, cost-effective instrument for the engineering geophysicist, geologist and hydrogeologist alike and has been particularly successful for mapping deeper groundwater contaminant plumes and for groundwater exploration.

Using the same patented inductive method as the EM31, the EM34-3 uses 3 intercoil spacings to give variable depths of exploration down to 60 meters. The EM-34 XL was developed to provide greater signal detection ability at the longer spacings. The XL employs a larger coil ~1.0m in diameter and it weighs about 1.5kg more than the standard coil.

In regions of particularly high cultural and atmospheric noise the higher powered EM34-3XL improves the signal to noise ratio by a factor of 10 at the 40 m spacing and by 4 at the 10 m and 20 m spacing.
