The lightweight robust exploders are a low cost firing system suitable for most users who require a safe, simple but reliable exploder.
Automatic firing is achieved by holding the key in the fire position until the circuit fires. When the key is released any residual charge left in the capacitor is discharged through a resistor. The exploder becomes automatically safe if the key is removed at any time. A neon indicator flashes to indicate that firing has taken place.
The exploder can fire a series of detonators in addition to a single detonator, housing is manufactured from robust high impact moulded ABS and is completely water and dust proof. A unique feature of the exploder is the use of sliding billet terminals. This feature makes cable connection especially easy and prevents the cable from damage.
The exploder is supplied in a hard-wearing leather carry case.
