VIBSIST-20 - The VIBSIST-20 is based on the Swept Impact Seismic Technique (SIST) which is a combination of the Vibroseis swept-frequency and the Mini-Sosie multi-impact ideas. The seismic signals are produced as a series of pulses, according to a specific pre-programmed sequence which makes the system similar to a smaller Vibroseis.

VIBSIST-50 - The VIBSIST-50 is based on the Swept Impact Seismic Technique (SIST) which is a combination of the Vibroseis swept-frequency and the Mini-Sosie multi-impact ideas. The seismic signals are produced as a series of pulses, according to a specific pre-programmed sequence which makes the system similar to a smaller Vibroseis.

VIBSIST-250/500 - The VIBSIST is a multi-impact, time-distributed source that uses a dedicated vehicle and hydraulic rock breaker, powered through a computer controlled flow regulator. The vehicle is powered by a Diesel 27 Hp motor with electric starter engine, moves at 5.5 km/h and can climb slopes of max 300. Temperature range for operation is, normally –35° to 55°C.

VIBSIST-3000 - The VIBSIST is a multi-impact, time-distributed seismic source that uses a hydraulic impact hammer mounted on 4_wheel drive / 4_wheel steering industrial vehicle. The vehicle has and high maneuverability, with a tight turn radius of 3.7m, can move at 40 km/h on public roads and climb slopes of 300.

SPH-54 Borehole
The VIBSIST-SPH is a Swept Impact Piezoelectric Borehole Seismic Source designed and produced by Vibrometric. A monotonous variation of the impact rate used to control effectively the non-repeatability of the impact intervals and achieve a wide bandwidth. Figure 1 presents the main modules of the VIBSIST-SPH.
