Frequency Response Function of a conventional streamer with different group length between 1.56 m and 25 m in 100 m water depth. For a typical 'high-resolution' streamer with 6.25 m group length, e.g., a not around 215 and 430 Hz would disturb a high-frequency airgun signal ranging from <100 to >500 Hz. Shorter groups are needed for shallow water seismics.

The solution for a conventional streamer were programmable units, which allowed to design the length of each group between 0.3 m and 6.25 m. Also mixed group length were possible.
