Nice one Gutted. Amazing stuff your doing.

Heads up, new version. See first post.

If you want to see the problem i fixed, enter these values with version 1.0:

B1: 10 degrees
B2: 15 degrees
B3: 23 degrees

Now repeatedly hit send on B3 LOL.

whoops.

Why did this happen? Because in the beta version you could not change data once entered. You had to hit reset button.. which is where the display scaling resets itself (the internal lines are scaled so they fit the bearing wheel nicely). Anyway I forgot to add a call to have it reset the scale whenever you change any of the bearings. This actually has another effect of the "show solution" lines being drawn in the wrong spots sometimes after a few changes.... despite the solution readouts being correct.

Perhaps this should be relocated to the Mods Section?

OK... new version is up. Version 1.1b (final version i promise).

It's a minor update:
Mainly to add support for units other than meters. Also added a "Minutes" label next to the Time Interval entry window to remove any confusion on what it expects.

Anyway, I don't foresee myself doing anything more with this for the time being. It does what it was supposed to do. Any more time spent on it will be more work for no real gain. The version of it that will be in Solution Solver 2.0 may (or may not) be enhanced somewhat both in UI & functionality. But as for this standalone version...I'm closing it's project file and packing it away. No more updates for it (unless there's a bug).

I could probably make the numeric up/down controls alittle less wonky, but thats a .NET framework thing. And it doesn't really bother me. I'll probably override their behaviour in the version for SS2.0.

Cheers, and love the included PDF really explains everything.Now I've no excuse not to practice Hydrophone use and triangulation.
Maybe i'll even learn some maths along the way

It's not a mod,

it's an external program.

I'd like to hear about your success's (or failures) using it.

I've only been in one situation where i could really use it.. .but It has already netted me a Queen Elizabeth Battleship.

I was in the southern blockade area of "Total Germany". Night time, medium fog. Decided to stop and listen and heard some very faint contacts. Sound man said they were closing so it was the perfect oppurtunity to try it (Long range and closing). 20 minute intervals was enough to get nice bearing spacing. The first bearing was done by ear, but I let the soundman report nearest contact for the rest of the beearings.. because it turned out to be a group.. and i couldn't distinguish which one it was myself,

After triangulation.. the estimated speed was 19kts!! wow... program must be fuxed i thought. I was not in a good position after triangulating the 4th bearing to reach a target that fast. So i drew an intercept and ran to it. As i neared the plotted course, the watch crew called out task force sighted.

Sure enough some escorts and two Battleships were about 3000 meters away coming through the fog. I Turned into what i figured was a 90 degree angle on them.. set speed on TDC to 19 knoots, 90 Starbboard AOB. Adjusted the scope till the gyro read 0.. and fired a salvo of 4 G7a's with a 3 degree spread once the first BB crossed the wire.

3 Hits on the BB. Several hours later she shunk.

So far every other contact in this patrol was either spotted visually, or was already too close on the hydrophone to use this, or was moving away when 1st heard. It's definately a situational tool.

Don't you love those adreanaline rushes.

Finally was in another situation to use it again.

Cimmaron Class tanker.. Long range on hydrophone & closing. It was so faint of a sound that the sonar guy couldn't hear him. He didn't hear him till i was about to take the 3rd reading lol.

Anyway, after an hour of listening.....
Estimation: 60 degrees @ 8kts.

I arrived at a spot 4000m away from where i thought hed' be, but it turned out he would pass more like 1500m in front of me. So i knew his course was slightly less.

My visual observations for the solution:
55 degrees @ 9kts

Fired two, One near the front.. other near the center. They both hit near the rear. Real target speed must have been 10kts.

Much better than just running around blindly chasing after the sound. I was actually waiting for him well in advance.
