Seismic Star II™ detonator is specially designed for the harsh conditions encountered in the modern 2-D and 3-D seismic patterns.
The copper shell ensures protection from the environment of salt and brackish water for long periods of time. Seismic Star II electric detonators will initiate all detonator sensitive seismic explosives.

Uses

Initiation of Seismic Explosives.

Advantages of Seismic Star II

Storage

SEISMIC STAR II detonators must be kept in dry and well ventilated magazines. Store in accordance with all applicable local and federal laws.
All detonators should never be stored in the same magazine with other explosives. For optimum accuracy, use within 2 years from date of manufacture under good storage conditions.
