US12312128 - Shock tube coil system

A shock tube coil system includes a housing, a plurality of channels for retaining a shock tube, and, optionally, a detonator. In some examples, the shock tube coil system includes hook and loop, a bag, or other means for removably attaching the coil system to a user, robot, or other object. A user is able to store the shock tube in the housing and withdraw as much shock tube is needed for a given application. The housing may be used repeatedly, with additional shock tube being inserted into the channels once emptied.
