WDJD-4A can more accurately detect weak geoelectric signal changes, thereby providing more accurate data support for geological exploration. For example, when searching for deep and hidden mineral resources, WDJD-4A can more accurately delineate the scope of ore bodies and determine their boundaries with its higher accuracy.

1. Transmitting power: The transmitting power of WDJD-4A is larger, which means that it can send stronger current signals underground, thereby increasing the detection depth and signal strength, and is more suitable for use in deep geological structure exploration and large-area census. For example, in deep metal mine exploration, the high-power emission of WDJD-4A can better penetrate the overburden and obtain information about deep ore bodies.
2. Receiving channels: WDJD-4A is equipped with more receiving channels and can receive data from multiple measuring electrodes at the same time, improving measurement efficiency and data collection density.
