You had one of your best days if you managed to hit a target that zig zaged what all the torps
Ive stopped to attack targets that zig zag unless iam not very close to them. My hit ratio on thos are about 30:1
If the target zig zag and are unarmed i surface and put some eggs in him whit my gun instead of waisting Eeels.
I find it much hard now than from sh3-4 to hit a zig zaging target, specially if its a long range shot.
