More information:

The Beethoven Mk 7 is a 100-shot capacitor discharge exploder, enclosed in a robust 'Noryl' moulded case. It is designed particularly to meet the requirements of blasting in gassy underground coal mines. The Mk 7 has an integral digital ohmmeter which can be used to measure the total circuit series resistance. The d.c voltage required to initiate the detonators is supplied by a hand operated generator which charges a capacitor.
