The GI-Gun (Generator-Incector Gun) is a seismic source used for high-resolution seismic imaging. The volume of the gun can be adjusted between 0.7 l and 1.7 l. The GI GUN has two independent air chambers within the same casing : the Generator (generating the primary pulse and creating the main bubble) and the Injector (injecting air inside the main bubble so that it collapses quickly). Hence the bubble osculation is reduced and suppressed compared to a single air gun.
