Since 1967 SIG is dedicated to develop & manufacture sparker / boomer systems with prime safety considerations. Systems are designed to achieve better resolution with penetration using low energy with adequate electrode.

SIG sparker-electrodes remain a reference in sound-sources. The SIG sparker-electrodes, or spark arrays, have a herring-bone pattern, with the tips sticking out each side of the central "bone", on one plane. These electrodes are then flat, easy to handle, and very light weight. No need of a heavy frame, or cumbersome catamaran. All electrodes are used with the same special floating cable, with an easy connection.

S.I.G. manufactures sparker / boomer energy sources, from 100 to 10.000 joules.

SIG16 hydrophone streamers are used worldwide for high resolution seismic and V.H.R. seismic
