Hiya,
If i have a pesky destroyer i try for a front tube shot to his oncoming bow at close range, At the same time i send a 30 deg shot to his port n starboard, This usually works if he starts to weave to avoid 1st centred shot
Also as said fish are pretty dud at the start like in rl
As for crashing, I would check as said in the above post
Can you replecate the crashing without tm installed ???
Not much help but also as said use scope quickly and watch depth and also i on/off tdc if i move direction so it renews again when i lockon (hope that makes sense)
Welcome Aboard
Have Fun
Def
PS: When you're comfortable and not crashing i really would suggest ROW and it's addons ohh and of course NSM4 (also a nsm4 row compat
) I use row/tm/nsm4 and some skins and hud stuff, Can always up a jsgme screeny if you ever want to try this mix
Bye
