Sonar in SH4 (with different important mods)

[XenonSurf]

Hi,


so when patrolling early in the war, from December 1941 until mid 1943 you are supposed to have the rudimentary listening sonar equiped, meaning a max. distance of 10.000 yards sonar range (I assume you don't have surface radar yet.)


From the description I read that these American sonars had surface detection capability for that distance which was really great in comparison to German sonars which AFAIK didn't have this possibility, but German detection ranges under water were much better (30-40 NM according to my research, but this is questionable, I only made a quick research.)


My problem is: At rough sea with 15m/s winds, I expect my sonar man to hear plain nothing, so I dive to 80 feet and go to full stop to make a sonar search. This search should yield a major distance in spotting targets compared to the surface search result, or no?
I never have spotted enemies that way, not in TMO, not in FORTSU or with other mods. The only sonar contacts were at surface in the 10Y range.


This also means that advanced realistic hydrophone plottings like the 4-bearing method must not be done in SH4, or because you have super sonar detection results at 10K Yards and you just move to visual range to get the enemy's course, or because you will never get sonar contacts further away than 10K Yards.



Is such a difference in sonar detection difference not simulated in SH4?



Thanks,
