Electronic Detonators

1. Hotshot

The Hotshot system is a fully auto-programmable system made by Detnet. This system has been designed to allow the blast designer to fire all types of surface mining or demolition blasts. Users familiar with non-electric systems find conversion to this system very easy. Hotshot has been made to replicate as far as possible the concepts behind those non electric systems, it only has to work with delay intervals.

An additional feature of the Hotshot system is the high level of security needed to fire the blast. Two security codes are needed to fire any blast.

2. Daveytronic
An alternative electronic detonator that can be supplied is the fully programmable Daveytronic system made by DaveyBickford. This is a two wire non polarised system.

These detonators are individually programmed by connecting each detonator in turn to a programming unit. Once programmed the detonators are clipped on to the firing line laid out along the rows. The programming unit also operates as a testing unit. These detonators have a maximum delay time of 14000ms and up to 1500 detonators can be fired from one blasting machine. All functions of each detonator are tested prior to firing.
