WHAT IS A BETSY GUN?

Betsy Guns are seismic sources that use propellant (gun powder) to produce deep penetrating acoustic energy, down to 2km in good conditions.


They not considered a firearm by the BATFE, that can be shipped, stored and safely used by any seismic practitioner in the US and Canada. 


Betsy Guns are lightweight, portable, and have a minimal environmental impact.

The BFG-1000 uses blank ammunition for a near zero environmental impact.

What Sets The Betsy Gun BFG-1000 Apart?

Safety 

  • Redesigned with user safety as the top priority, today's Betsy Guns are safer than a sledgehammer.
  • The BFG-1000 is electronically initiated allowing users to stand safely away from the system.


Data Quality 

  • 117kJ of energy per shot, equivalent to one hundred 16lb sledgehammer blows.
  • Frequencies as low as 2Hz enable deep penetrating seismic reflections down to  2 km depth and enable processing techniques like FWI.
  • Great for refraction studies in noisy or highly attenuative environments.
  • Frequencies up to 200 Hz produce high resolution imagery in the shallow subsurface. 
  • Ideal source for surface-wave analysis and site hazard classification. allowing shear wave velocity estimation down to ~300 m
  • Generates tube waves that are a source of vertically polarized shear waves (Sv).


Accessibility

  • Betsy Guns are affordable, durable, and easy to maintain. 
  • The Betsy Gun is not considered a firearm by the US Bureau of Alcohol, Tobacco, Firearms, and Explosives.
  • Blank ammunition is exempted from most ammunition laws in the US, and can be shipped to any state or US territory.
  • Betsy Guns and ammunition are available in the US and Canada.
