More sonar questions

nutworld · 12-29-06, 03:31 AM

I'm still working on my sonar skills, this time using Bill Nichols "VENGANCE" scenario, where my 688 has to locate, identify and kill a Kilo.

My question is this: Don't contacts in the NB display that look something like this ___^___ signify a contact at that designated bearing? (please forgive my "graphic")

When playing this scenario I hear the surface contacts that "seem" to be surface squall, and those lines appear solid on my waterfall display in the BB waterfall.

When I click on the designated bearing that I show above, my NB waterfall display shows no contact lines.

I'm not looking for cheats or things like that but I just don't understand why my NB display would show what "seems" to be a strong contact, showing nothing on the waterfall.

Thanks for your help.

Just for sure, check your frequency scale settings. You can have frequence scale 50Hz while the visible line is 2000 Hz.

Anyway, noise signals are visible only on BB displays (which in fact is the spiky line on NB too). They have no distinct frequency. In DW, at least helos and shrimp are such contancts. With any sub or ship should give nice lines much sooner than you are able to see bump on spiky line.

Thanks Dr. Sid

I did in fact "scroll" thru all my frequency scale settings, in case sonar was picking up something on another frequency.

The "contact" stayed on the display but nothing appeared on the waterfall display at any frequency.

When in doubt, use 'show truth' option. Both shrimp and low flying helos are very rare.

I would also agree that you are seeing a biologic on the BB, which doesn't produce a NB line.

OK.

That answers a question. I love the scenario. I read the book that he based the mission on, and I'm loving playing it.

When I went up to PD, and took a look, the sea state is TERRIBLE, and of course there is precipitation, and that is what I thought I was seeing on my BB waterfall. I, of course, hear the biologic(s??) when in BB as well.

I've not gotten a sniff of the Kilo that is out there somewhere, and I'm 4 hours into the mission.

I don't want to "truth" because I want to develop my sonar skills, so that eventually I get to play MP missions, and not get KILLED immediatly.

My next question then is this:
using a "Yes" or "No" answer (so I don't lose all hope and quit) would someone with GOOD sonar skills have found the Kilo in 4 hours?

Or is the Kilo that silent, as it has been "made out to be" in many books, including the one that this mission is based upon?

Thanks for the help and suggestions guys. I know that it's probably frustrating when a NEWB like myself gets going asking all kinds of questions, but I really do want to learn.

Yes. Me.:p

But yeah, the kilo is VERY silent. the silentist in the game, i think. I understand why you have trouble finding it....

p.s.: no, your asking questions is why alot of us are here. its not annoying at all....infact, keep asking them. It gives us something to do around here.
