A socket driver for a perforating gun assembly. The socket driver includes a first end, and a second end opposite the first end. The second end defines an inner diameter that has a length to extend over a threaded end of the tandem sub. The socket driver is configured to mate with a shoulder along the tandem sub of the perforating gun assembly. Specifically, the socket driver includes a radial notched profile. The notched profile is configured to mate with a radial pattern of slots along the shoulder of the tandem sub. In one aspect, the socket driver is between 3 and 8 inches in length. In one aspect, the first end of the socket driver comprises an opening configured to receive a torque tool. A method of connecting ends of perforating guns using the socket driver is also provided herein.

An initiator head may include a housing extending in an axial direction, a circuit board provided in an interior space of the housing, a line-in terminal provided on a first side of the housing in the axial direction and accessible from an exterior of the housing, and a fuse displaced from the circuit board in the axial direction. A thickness direction of the circuit board may be substantially parallel with the axial direction. The line-in terminal may be in electrical communication with the circuit board. The fuse may be in electrical communication with the circuit board. The circuit board may be configured to activate the fuse in response to a control signal received at the line-in terminal.
