Stanlay STREAM-EM

STREAM EM represents the most advanced technology sub-surface tomographic radar equipment worldwide for EXTENSIVE 2D/3D ASSET MAPPING based on massive arrays of multifrequency, multipolarized antennas setting unprecedented standards for accuracy and productivity in sub surface mapping.

STREAM-EM is years ahead of the market in technology & make possible what was only a dream until now. STREAM is designed for mapping of underground utilities in massive areas of tens to hundreds of sq kilometers while providing very high resolution mapping. Traditional single-frequency or manually operated GPRs simply don't permit this, while other existing vehicle towed GPRs do not assure an acceptable level of utilities detection. STREAM- EM has been conceived to cover tens of hectares/day.
