Non-electric and electric blasting caps BS No.8 :

There are three different Czech non-electric blasting caps.
These are distinguished by their copper, aluminium, or steel jacket.
All other characteristics of the caps are the same.
These caps are supplied in containers ranging from 100 to 10,000.
The BS No.8 blasting caps have the same explosive characteristics as the Soviet No.8 blasting caps.

Electric detonator adapter MT :

The MT electric detonator adapter consists of either a plastic or metal cup with the two conducting
wires 1.5m (5.5ft) long attached to the end.
This adapter is used in conjunction with non-electric firing caps by adapting them to electric firing
circuits.
The MT electric detonators come in containers of 100 each.

Blasting machines DEOS 25 and DEOS 50 :

The DEOS 25 and 50 electrical blasting machines are hand-operated, low-tension electric generators.
Each machine consists of a case which houses a steel magnet, armature and gear assembly.
A shaft projecting from the gear assembly is turned by a T-shaped wooden handle, hand crank inserted through a hexagonal nut in the cover.
Opposite this nut are two terminals.
The DEOS 25 is capable of detonating up to 25 electric caps wired in series through a maximum external resistance of 110 Ohms.
The DEOS 50 is capable of detonating up to 50 electric caps wired in series through a maximum external resistance of 300 Ohms.

Weight DEOS 25: 3.18kilo
Weight DEOS 50: 5.20kilo.
