hachiman · 03-21-07, 08:48 AM

Hi

Heard some reports the hydrophone does'nt work at peri depth'but a few metres below this

Is this true??

Yes that is correct. I'm not a 100% sure about the exact depth figure but from what I heard you have to be at/or below 20 meters for it to operate.

Can some1 confirm 20 meters?

Regards,

Mike

I don't ever remember giving the order:

"Dive, make your depth .... meters" LOL!

Shouldn't sonar work at periscope depth though? At least to a degree? The sonarman would always call out "Running hot, straight, and normal" after torpedoes were fired during an attack run. Since in real life, a sonarman would hear the torpedoes and make sure they were running normally, I would think that sonar would function to a degree.

So is'nt that a bug?
You could listen at PD in SH3!!

Sonar should work at PD, yes. I'd have to look at plans, but I think later fleet boats had primary sound heads on the underside of the superstructure. The late-war FM sonar I think had them topside.

I've seen game reports of enemy ships passing at 400 yards and sonar not hearing them. This is just wrong--you can hear a skimmer at 400 yards with your ears while standing in the middle of Control. With a Dixie cup on the hull you could hear the skimmer's CO ask for more coffee. I think this isn't modeled correctly.
