WHAT IS A BETSY GUN?
A class of seismic sources that use propellant to produce deep penetrating acoustic energy (up to 2 km).
A tool, not a firearm, that can be shipped, stored and safely used by any seismic practitioner.
A leave-no-trace seismic source which minimizes 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.
