Towed LandStreamer for MASW, reflection or refraction surveys

The Towed LandStreamer is a geophone array specifically designed for fast, high-resolution, and cost-effective land seismic acquisition. It is particularly well suited for near-surface seismic methods such as reflection, MASW, and refraction, where a towed solution offers significant advantages over conventional streamers with planted geophones. A typical complete system includes a LandStreamer with any seismograph, and an AWD source.

Although, highest data quality can be achieved by dragging the streamer on solid surfaces, such as roads or runways, it can also be used in the more adverse conditions, such as dirt roads, sandy surfaces, mudflats, deserts, etc.

The design of the streamer is exceptionally robust and easy-to-use. We offer two types of steel bases — one for dense surfaces and one for loose terrain — each can be quickly swapped on your LandStreamer. The design and weight of bases ensures the required coupling for ground motion registration.

The stabilizer is easy to install and protects the geophone from tipping over when encountering obstacles. An inter-section platform provides secure connection between LandStreamer segments and helps reduce the overall transport weight of the system, lowering logistics costs.

Any type of geophone can be used with the LandStreamer – low frequency or standard vertical, horizontal, multicomponent (2С or 3C), and omnidirectional.

LandStreamer is compatible with any multi-channel seismograph and can be manufactured with the required number of receivers, spacing and lead-in cable. An important feature of the design is the ability to quickly disconnect geophones from the platforms and spread cable from the belt for further planting with conventional spikes.

Thoughtful down to the smallest details We spent years conducting geophysical surveys before dedicating to equipment design that would make field geophysicists’ life easier. We implemented all the ideas that came to us in the taiga or mountains, under the scorching sun and during polar night. The LandStreamer features easily removable stabilizers, curved upward to avoid snagging on side obstacles while still preventing the geophone from tipping over on relatively flat surfaces.

We can manufacture LandStreamer in modules for convenient handling and reduced transportation costs. If required, we can also supply the system in transport cases.

The base plates are made of hard steel and are abrasion-resistant for long-term durability. The easy-to-replace tripod support provides stability, delivers high surface pressure, and enables the unit to plow into soft ground for improved coupling. Two types of base plates are available to ensure optimal performance on any surface accessible to the LandStreamer.

We use only the most durable strap on the market, with a tensile strength of 10,000 lb (~4,500 kg). It is firmly clamped between the top and base plates without perforation or damage. At the same time it allows you to easily reposition the plates along the strap to adjust spacing as needed for your specific survey requirements.

The LandStreamer comes with spread cables equipped with KCL (Kooter) connectors. This design minimizes the possibility of snagging, making the system more robust and long-lasting.

Spacing between sensors is easily adjusted to fit the needs of the survey. LandStreamer can be used with any seismograph on the market, from conventional DAQlink / Geode / Terraloc Pro to telemetry X One and nodal systems.
