1. A seismic source comprising:
a reservoir configured to hold compressed gas;
a first firing head coupled to the reservoir, the first firing head configured to generate seismic energy by releasing a first portion of the compressed gas from the reservoir to form a first gas bubble in a seismic medium; and
a second firing head coupled to the reservoir, the second firing head configured to generate seismic energy by releasing a second portion of the compressed gas from the reservoir to form a second gas bubble in the seismic medium, wherein each of the first firing head and the second firing head comprises individual control components configured to allow the first firing head and the second firing head to be independently fired; and
at least one first fill line coupled directly to the reservoir.
