Hydrophone range

Both, and the weather conditions are Calm and Sunny.

What is your depth at that time. The hydrophone only kicks in below a certain depth, and your sub might be bobbing up above it depending on wave action and your speed. Without the popular mods stock SH4 should have unimpeded hydrophone coverage. Or the background noise might be to loud for you.

I was at a dead stop, and at PD, maybe that depth is too shallow then?

:runs off to see what happens at a deeper depth:

Dont dive too deep though because diving below a thermal layer would (or at least should) also make it hard to pick up contacts.

Not sure of the stock game, but I don't think passing the thermal layer has any effect on sonar, it doesn't in any of the megamods.

Being on the surface the hydrophones work fine under most circumstances. The S boat doesn't work on the surface. A small depth issue may apply and most subs sonar works fine on the surface. In stock many of the subs almost ride on top the water, this can be a problem.

However, being at scope depth, I don't see that you would have a problem at any level. You should be able to hear ships yourself in the contact zone, 20NM's or so.

They're are a few ships when they run below 7kts, they don't show on sonar.

I'm new to this game and have no idea what to do. I dont think my sonar works. I cant ever hear any ships. Any advice?

Jason, you must point your Hydrophone towards an enemy ship, when you can hear its engines you can then use the sonar to ping the target giving its range.

Back to my problem....

I tried again, and used the Hydrophone as you would, and a target appeared as 'unknown' on the notepad in the upper left corner, but was unable to hear anything what so ever, at least not until it was closer to me.

When I asked my crew to 'follow nearest contact' he responded with "SO No sound contact"
