Also be sure you don't drag TA (towed array) on the bottom (you'll see bright noise on the screen). Don't extend your TA to the full, 1/3 is enough.

Dr.Sid are you sure about this ?
I though that maximum sensitivity was achieved by extending completely the TA.
Does LwAmi model this ?

As with everything in this game, it depends on your tactical situation.

Of course, I know that if you're in shallow waters extending completely the TA would prove mostly useless as it would drag on the seafloor.
I was talking about situations where you can extend completely without problem the TA.
Case in point : patrolling in the mid of the atlantic, or in the mid of the pacific.
In such cases why would you NOT WANT to ? :hmm:

If there is any gain in sensitivity after deploying the TA about 1/3 of the way, I haven't noticed it. That does't really bother me much, since that's still a long way from the boat and any interference it might be casuing. Don't forget that the LW/Ami TA's are substanially longer than the TA's in stock DW.

As for why not to deploy it all the way... reaction time. Sometimes you really want to start that other leg sooner, and having the TA in a turn makes it pretty useless. The sooner its back on track, the more data you get. The only reason I can think of why you'd want it longer is better triangulation if you get a second array on the contact.

1/3 .. quite sure. You can see it on BB display when deploing TA. After 1/3 there is no noise decrease or signal increase. And reaction times matters a lot.

If true, then this is something for our resident modding man to take a look at.

Maybe some improvements should be incorporated in a future version of lwami.

- increase sensitivity of the TA proportional to how much of the TA has been extended.
- make bearing error of TA dependent on its length so that triangulation is less acurate with a short TA and more accurate with a long TA.

There's other important thing about extending the TA to its maximun... you can go just above the layer at 3 knots...and the TA will fall below the layer... the longer the cable, the best this can be done... and of course with LWAmi this is very easy to do because the cable is longer than in stock.

EDIT: I know it can be done, if you look the 3D screen you can see the cable bending down... and I think it works that seems to me when I tried this, but I'm not so good in this game to know if it works or is just my imagination...

This should not be needed. TA LOBs originate in actual TA position. If you got Hull & short TA you get narrow triangle where TA bearing error matters more. If you have long TA you get wider triangle and error matters less.
This is done realisticly enough in DW. Real TA sensor does not chage error with extension amount.

I can't change the variable TA sensitivity, since it is hardcoded in the interface, although I'm generally very happy with how the TA's perform now (except the dead cut-off if they fall below 3000ft, but I've got to look at exactly why that is the case before I just go and change something).

Modulating the length of the TA depending on the tactical situation is a crucial aspect of maneovering your boat. The TA is basically a long extension of your boat, so you have to handle it smartly to be effective.

Perhaps the most crucial ASW tactic in DW that has been ignored completely is using the Towed Array sonar as a dipping sonar for seeing under the layer. One player aware of this tactic will always defeat another player unaware of this tactic in ASW combat, all things being equal.

I can't think of another reason to have the TA deployed to its full length unless you are trying to hear around a sea mount or other terrain.

Cheers,
David
