When operating in a tactical environment where simplicity and consistency are key, WMDTech has produced a single button firing device to initiate both electric initiators as well as non-electric shock tube. This is a handheld firing device, with a physical block safety over the firing button. Initiation is as simple as sliding the physical block out of the way, and holding the firing button for a 3-count. Initiation is consistent, even with shock tube, as we use an easily replaceable shock tube head that also serves as a quick disconnect in a tactical environment.
