Deep Dive

Multidimensional results show

To enable on-site engineers to always have a clear understanding of the quality of the observation data, the GD series host provides a variety of data browsing tools, including a list of measurement points (with detailed data), profile diagrams, cross-sectional diagrams, and waveform diagrams of the transmitted and received signals.

2D/3D scrolling function

2D scrolling, with limited cables, enables longer cross-section tests. The measurement points are not repeated, thereby enhancing the on-site work efficiency. 3D scrolling, where small areas are combined into larger ones, increases the automatic coordinate conversion and makes the cross-section more complete.

Rich and diverse connection methods

A variety of wiring methods and connection techniques are provided to meet the requirements of different terrains and customer needs, ensuring the authenticity and accuracy of the data to the greatest extent.

Electrode settings for multiple scenarios

Support equidistant jump electrodes. Small-spacing cables can complete tests with large electrode spacings. In the field, when encountering rocks or gullies that make it impossible to install electrodes, the position can be left unconnected, which will not affect the testing of the entire section. The system provides a detailed list of grounding resistance test data, allowing for intuitive location of electrodes with poor grounding. After taking grounding improvement measures, the affected electrode can be retested individually, or a certain cable can be retested, avoiding the need for repeated full retests. This can not only save field batteries but also improve testing efficiency.

Rich programmable scripts and data processing

Based on the concept of test programmability and customizability, Geomative Studio has designed a scripting method. Users can plan the test area and trim the measurement points in advance. The system supports scripts based on standard devices for trimming, as well as custom scripts that can be fully customized by users and imported from external Excel files. To reduce interference between the measurement points before and after, the script supports three test point testing sequences: layer-by-layer, rolling surface-by-rolling surface, and staggered random. After data collection is completed, Geomative Studio manages the host data and supports the export of various file formats such as txt, excel, dat, and urf, facilitating data processing. At the same time, terrain files are added to the exported data for inversion.

High-density cables are core components of high-density electrical prospecting. They connect to electrodes through multiple taps, transmitting underground electric field signals to the cable head for acquisition and switching. Made with a copper core and TPU outer sheath, they are flexible and tensile-resistant, suitable for deployment in complex field environments. The maximum transmission voltage is 800V, and the maximum transmission current is 2A, compatible with the full range of first- to third-generation electrical instruments. The entire set of high-density cables is structurally divided into two categories: centralized and distributed. The centralized type is further subdivided into three scenarios: land, surface water, and underwater/well. Each secondary category is also classified into single-tap and double-tap based on the type of tap.

High-density land cables are the standard signal transmission lines for terrestrial electrical prospecting. They connect to electrodes through taps, with all tap signals transmitted to the host via a single cable. The cables feature a copper core with a TPU outer sheath, offering flexibility and tensile resistance, with a maximum transmission voltage of 800V and a maximum transmission current of 2.5A. Tap spacing ranges from 0.5m to 20m, supporting multiple specifications of 5/10/15/30/60 taps. Depending on the tap type, they are categorized into single-tap and double-tap cables, suitable for both land electrical profiling and areal surveys. Single-tap cables utilize a single tap structure, connecting each tap to electrodes through an independent channel. Their simple structure and easy maintenance make them the mainstream choice for high-density electrical prospecting.

DC Power Booster is a DC voltage enhancement unit designed to support high-density electrical exploration. It does not contain a built-in battery and achieves DC voltage boosting through an external 12–48V DC or 220V AC input. The BP-600 supports six selectable voltage levels: 100/200/300/400/500/600V, with an efficiency greater than 90%, suitable for extreme cold down to -40°C. The BP-1000 features an adjustable output ranging from 0 to 1000V, making it suitable for high-power electric exploration scenarios.

- Specifications: 600V six selectable levels / 1000V adjustable, efficiency >90%
