Yup, but I take that into account too. The only gamble I make is that they don't make a course change. Because that can happen at any time. If I can't intercept them before they moved 170 km, then I leave them be. (it's the distance at which your hydrophone range won't fit into the 22.5 degree contact course wedge anymore)

nice to know 170KM is actually the distance that it will evade a 20KM circle at. never really bothered working it out even though it's a simple cosine rule lmao but i think i will stick to 150KM because we all know how dodgy a hydrophone can be at long range and bad weather. i have gotten contacts at around 22-23KM and not seen others until 16-17KM away from me(fyi i am at the right angle and they are not sneaking up behind me.i listen at all stop which i think/hope makes a difference from slow)

Nope, 170 km goes with 33km radius circle. That's the max range if you listen yourself.

Maceaciadh 08-30-12 09:01 AM
is that with the first type of hydrophone or a later improved one? well i dont listen myself, perhaps i should start though if your range is increasing by 50%!

edit: just worked it out now that after 102KM the ship could be outside a listening range of 20KM
