GHG or KDB ?
 

Just out of curiosity, which one out of these two do you guys prefer and why? Pros and cons from your experience with these devices?
Thanks for the replies.
:up:

The upgrade (forgot which one...at work right now)....because it has a wider listening arc :arrgh!:

The KDB is better because it's pivotable and has a wider listening arc. A contra is that it brakes fairly easy under DC attack.

I've tended to always steer clear of the KDB because of the description that it breaks easily. I've recently tried upgrading to it, but managed to avoid any serious D/C attacks so far, so it's untested. Just how easily is it likely to break? Will it break before anything else, or is it at just risk when other damage is being incurred? Obviously it's a critical piece of kit, so I'd like to avoid losing it...

It's not that breakable as in the description. You need a pretty close hit to have it damaged or even destroyed and by then a broken hydro is probably your lowest concern...

Aaand then there is the "Balkongerät" in mid 1943!!! Try it you'll like it!!

:D

When you get the KDB you do not lose the GHG. They are both there.

GHG has about a 20 degree blind zone in front of the sub and about a 60 degree blind zone in the rear. KDB eliminates the front blind zone and reduces the rear one to about 40 degrees.

Darn shame that manually using the hydrophones gives you a fully functional 360 degree listening area. :down:

I think the limit is not a hard one, the hydro rotates 360º, the blind (should be deaf) spot it's because of your own propellers noise.

There is a blind(deaf) zone limit in the Sensors.dat file from the BearingMin and BearingMax entries. This zone seems to work correctly on the Navmap (the sonar contact line will not be updated properly when in that zone even if you are stopped) if your crew is running the sonar. However, as Albrecht Von Hesse points out, if you are at the Hydrophone control station running it yourself, I don't THINK the zones apply and you can hear in all directions.

This is part of the reason I always like to let my crew man the hydrophones and not me (also deckgun and flak)....but they are just to unreliable at detecting obvious things.
