Dyno Nobel released the EZshot EZDet series for surface blasting.
Units consist of a green shock tube with a surface detonator attached to one end and a high-strength in-hole electronic detonator on the other. The surface detonator is inside a color-coded plastic EZ Connector block for easy connections to shock tube leads, and can hold up to six shock tube leads. Easy-to-read, color-coded delay tags display the delay number and firing time prominently.
Units can be easily connected to one another to satisfy basic blast design requirements, the company said. They can be used in combination with NONEL MS, NONEL EZTL and NONEL TD detonators for complex blast-design requirements, and to minimize inventory of initiation system components.
