How to kill Kilo

[BigBadVuk]

Hmmm..well it is quite simple....This little thing is quiet as hole in the water!..Evry time i get fix on her she is probably already sending me 1-2 fishes.
...I perfer to drive SW but looks like that even on small speeds (2-3kts) this little bastard can detect me always before i found her!There is only 2 tactic wich i found to be helpful(sometimes ):
1. Use layers!..in 1.03 they r strong enough to protect u even from active sonar!
2. Use active sonar,and get the pinpoint on kilo becos she will get fix on u if u relaying only on passive methods(but i dont like this 1)!

Any tips and tricks ?
Oh..yes..I use LWAMI latest version!
