For Rent

Seismic 750lb Accelerated Weight Drop

Big Bang 750lb Accelerated Weight Drop

Item # 109577

The "Big Bang" 750 lb Accelerated Weight Drop Seismic Source from 3D Geophysics is a brute when it comes to delivering the power needed for great, clean reflection or MASW data but a sweetheart when towing down the road. Earlier models have over 50,000 miles towed at speeds of 55-65 mph.


The source uses an electric-start motor and hydraulics to move the mass and employs a 2' x 2' end on hammer - no separate plate.

A convenient receiver hitch is ready for a hook to a land-streamer.




The source is located in and rented from the EXI Harrisburg, PA office. Please contact that office at 717-303-5406 directly for rental requests.
