Another point about sonar/sound conditions is that all the different hydrophone units in use had varying degrees of bearing accuracy. With the GHG units, for instance, bearing accuracy degraded greatly around the bow area. That was the big improvement of the Balkongerat over GHG: accurate bearings could be obtained in a wider arc. The current modeling of GHG in SH4, where there is just a 20-degree dead zone around the bow, just isn't all that accurate. Bearings with GHG in this area should be obtainable, just highly inaccurate.
