Good point: if the icon has faded beware! however it can still be estimated from speed given to approx. position along the course line. The object is primarily to readily put the uboat athwart the target's likely course to enable the sound man with his hidden enemies upgrade to tighten on the actual location. Tha advantage is you generally are ahead of an oncoming target in the ideal position. I play all unmodified and it works for me. Ps: I AM a Pisces so it's all fishy mit der eels anyhow!
