you might also, if you're so inclined, try the new values for the thermal layer i came up with (see ==> http://www.subsim.com/radioroom/showthread.php?t=109573):

in sim.cfg, under [Hydrophone] set -

Thermal Layer Signal Attenuation=1.7032 ; where '1' means no signal reduction and '3' equals signal reduction to 33%, then '1.7032'=signal reduction by 22.5% (ie the angle of refraction assuming an averaged 45deg initial source)

and under [Sonar] set -

Thermal Layer Signal Attenuation=2.0078 ; where '1' means no signal reduction and '5' equals signal reduction to 20%, assuming a HF pulse of 35KHz and max 'nominal' emmissions of c20KHz gives a modifier of 1.75 which, when compounded (to account for crossing the thermocline twice), produces '2.0078'=signal reduction by 19.69% (apparent attenuation)
