Hand-Cranked Blast Exploder
The Suprex 621F shot exploder from AEC Electronics is capable of firing up to 25 StatSafe detonators connected in series where the total blasting circuit resistance does not exceed 25W. The unit is housed in a toughened plastic enclosure and is fully water resistant. The exploder is powered by means of a hand-cranked dynamo and fires automatically after a period of two to three seconds. A lamp glows dimly during charging and flashes when the unit fires. www.aece.co.za
