Sounds to me like the new long streamers just don't see the
grounded target as a good ground! Does the new TC operate at the
same frequency as the old one? If not, then I would immediately
investigate the impedance to real earth ground of that grounded
target *at the new frequency*. Perhaps at the frequency of the new
TC you have a high impedance in the ground connection: the series
inductange of the grounding wire partially parallel-resonating with
capacitance to ground of the target?

Sorry, how do I get that guide? Thanks.
