Exel™ HTD Detonators are shock tube based detonators designed to control the millisecond delay sequence from hole to hole, across the surface of a blast. The special design of Exel™ HTD detonators allows up to six outgoing shock tubes to be initiated and provides security of tube retention.
Exel™ HTD detonators consist of a length of Exel™ shock tube and a low strength delay detonator. The free end of the tubing is closed with a waterproof seal. The delay detonator is fully enclosed in a unique colour coded handiblock.
