Colin Clarke – Sonar is nothing like in the movies

So a bit on the movies where you constantly hearing ‘ping’, we don’t do that.

That’s all theatre, that doesn’t happen ‘cos if you’re transmitting, you’re just telling someone where you are, you’re just a beacon aren’t you?

You’re telling that listening platform where you are, so the idea is to remain stealthy and just use passive sonar, so just listen for the noise in the Ocean, not go active.

You’re active sonar helps you with confirming a range and bearing of something ‘cos you can just transmit straight out, get a reflection, it’s definitely down that bearing and now I’ve got a range through the passive sonar, that’s the bit you’re struggling for.
