Shock Tube Detonators
This is a No.8 strength detonator system designed for surface bench blasting. The principle is that the same delay period is used for each hole with the timing between holes being effected by surface delays incorporated into connector units. For double decked holes a common delay period is used for the bottom deck with another common delay for the top deck. Unidets are available in the following delays;
SL Connector Units
SL Connector units consist of a plastic block fitted with a mini delay detonator. Each colour coded block can initiate up to 7 shock tubes in both directions. The following units are available:
*Nominal 2 ms.
SL Starter Lines
This consists of an SL0* type connector with a 50m or 100m long shock tube on a reel for connecting the blast round to a Dynostart blasting machine.
