GeoTomographie BIS-SH-DS
The borehole source BIS-SH generates horizontally polarized shear waves (SH) and compressional waves (P). The seismic signals are highly repeatable. The source works in dry or water filled boreholes and can be used in vertical or horizontal boreholes.
Energy released by the IPG5000 discharges through a system of electromagnetical coils adjacent to a copper plate (needs to be used with impulse generator). If the plate is rejected a mechanical impact to the borehole wall is generated. The borehole source is coupled to the borehole wall by a pneumatic clamping system (inflatable bladder).
The orientation of the source is controlled from surface by a torsional stiff hose. Generated wave types: SH/P Signal frequencies: Up to 4 kHz (depending on geology and borehole distance) Operational depth: Up to 200 m Source length: 880 mm Source diameter: 65 mm Source weight: 8.5 kg Cable weight per metre: 665 g Borehole diameter: 75 - 100 mm (or larger if spacers are used) Clamping system: Inflatable bladder Orientation: Torsionally stiff hose Depth indicator: Cable marking every 2 m Connector: To Impulse Generator IPG5000

Every rental ships with the cables, batteries, chargers, and documentation needed to survey on arrival, packed in a transit case. Tell us about your job and we will confirm the exact configuration for your dates.
Datasheets, quick-start guides, and field videos for the GeoTomographie BIS-SH-DS are available on request while we build out the library. Ask for the documentation pack.

Pick your dates and we will confirm availability, final rates, and a proposal, usually the same business day.
Choose your dates
Rental days run door to door and include weekends. From 28 days the monthly rate applies automatically.
Shipping
Rentals travel on your own carrier account in both directions, so freight is billed to you directly and never marked up by us.
