Current systems for underground geological surveys rely on a shockwave travelling through the ground and reflecting back from different materials (limestone, sandstone, ores etc.). Each material has a signature which is picked up by a receiver and displayed in a number of ways.
Current shockwave generation is by striking an on-ground steel plate with a sledge hammer or firing a 12-gauge shot gun into the ground, or setting off a small in-ground explosive device, or using large hydraulic impact hammer devices.
Not one of these methods provides a consistent shockwave and as a result readings and accuracy vary.
To achieve accurate and consistent shockwaves, large and not easily transportable equipment is required, thereby causing logistical problems in difficult terrain and shallow water sites.

a seismograph print out of a test carried out using the HVL~CO system at the
University of Tasmania. It clearly shows an even and consistent shockwave
picked up by all geophones.

Poly Systems is developing an Air Horn capability by harnessing the benefits of liquid CO2 over the conventional use of large volume on deck air compressors and the associated problems of pumping and operating with a gas at depth.
The ability of liquid CO2 to be pumped to any depth and as required, provides a time nominated given volume of gas discharge to enhance the quality and slash the cost of deep water survey work.
Due to project development progression, we apologise that we are unable to display the achievements of this technology.
A variant of our HVL~CO Weapon System is being trialled because of the ability to provide an accurately metered, high-energy pulse at prescribed intervals.
This offers either a low frequency shockwave or a physical shockwave from an HVL~CO generator, easily carried by one person into difficult terrain and shallow water work.
The adaptation of the HVL~CO technology has world wide applications in geological surveying, mining and oil exploration.
