I listen to the sonar lots while on patrol and I'm constantly picking up what sounds like ships but very far away, there are often at least 2 or 3 of these sounds coming from different bearings. Sounds rather like heartbeats and the longer I listen it sounds more like 2-3 heartbeats together.
The thing is I chase these contacts for miles and never get any real contacts, am I getting false readings?
Really need to know if I'm wasting my time as it's getting very frustrating chasing what at the moment appears to be nothing and wasting precious fuel
