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)
