Dyno Nobel’s GeoShot® Seismic Electronic Initiation System is another in the suite of Net Explosive Quantity (per 100 units) 0.1000kg
Dyno Nobel electronic systems. Built on the proven DigiShot® platform, GeoShot
provides an electronic solution to our seismic customers’ need for security by using a Hazardous Shipping Description
system-specific, coded command for detonator communication during testing and

firing. As a precision electronic initiation system, GeoShot provides excellent data
acquisition and reporting. In addition, the GeoShot detonator is produced with robust
over-extruded downline wire for additional abrasion resistance plus an easy to deploy
coiling configuration which facilitates hole loading efficiency. Packaging
