Abstract
Disclosed is a firing device for shock tube. Shock tube is a non-electric explosive initiator, well known to those of ordinary skill in the art. The firing device is configured to provide a redundant dual-ignition capability for connected shock tube. In this way, a second attempt to initiate the shock tube can be made immediately following a failed first attempt. To provide this functionality, the firing device includes a primer tray that can be preloaded with two primers. Using an operably connected selector, the primer tray can be rotated between use positions that individually locate each primer for detonation.

A firing device for shock tube comprising:
- a body having a shock tube adapter on one end;
- a primer tray configured to hold two primers;
- and
- a selector operably connected to the primer tray;
- wherein:
- the shock tube adapter is configured to connect one end of shock tube to the firing device;
- the primer tray defines two primer apertures and can be rotated between two use positions, each use position aligns one of the two primer apertures with an interior tubular aperture extending through the shock tube adapter.
