Depth under keel

[BulSoldier]

Actually ingame pinging the bottom wont give away your position.It is undetectable by the enemy,also firing torps or blowing ballast wont be detected by enemy.In RL it was detectable.
I dont blow ballast or pingig if enemy is nearby something like honor rule

Gwx 1.03 here but i think this thigs are hardcoded and are present in 2.0

Are you sure about that?
IIRC the manual says something about that you have to be carefull
with the pinging when escorts are close, but I could be wrong.

Well i heard it from around here and tested it with success (havent been detected) i too could be wrong, lets wait someone with greater knowledge to say.

SHIII manual tells you to be careful about it... however, I don't think is moddeled... In fact, you are able to get depth under keel on a non-sonar equipped sub .
I might be wrong but... don't you need a sonar to ping? Or is it just Bernard yelling a very high-pitched tone to the sea bottom?

It was a very simple sonar device that sent a signal straight down. You can operate it manually from the navigator's table. They all had it, it did ping, and it could be detected. In the game? Now you've all got me wondering.

AFAIK you'll NOT be detected.
Pretty unrealistic imho but it just isn't modeled in (stock) SHIII

I know, but, is it realistic to have an Atlas Echolot that pings and not to have a sonar? I don't know, just asking.

lol, good to see many share my doubt :p

Like I said, I never got the impression from the AI that pinging the bottom provoked any reaction at all.

I'm pretty sure they did have the sounding device long before they had active sonar. Why? I have no idea, unless it's maybe it's that the echelot requires a simple push of a button, and sonar requires a complex system and a highly trained operator.

The type VIIC had the S-Gerät, which was essentially active sonar with a range of around 4000m. One of the reasons the VIIC is bigger (control room is longer) then the VIIB is to accommodate the transmission sound head.

As far as I've ever been able to determine, nothing smaller, nor designed earlier, then the VIIC had active sonar.

The echolot is a much smaller device and sends out only a low-power pulse. Even then, I'm not sure if the smaller boats (like the type II's) had both the shallow and the deep water versions - I suspect they only had the shallow water versions for the same reasons - space for the higher-power transducer head.
