Basic scanning question.

I've seen tutorials about how to arrange the probes and what not, but I can't find anything explaining in depth, the different types of icons that pop up.

If someone has the time to explain the following, I'd appreciate it a lot.

For simplification, let's assume that there is only one signature on scan. (Unknown)

I've filled in the ones I'm certain of what means.


1.Red sphere:

2. Red circle:

3.Red dot (often a times there are multiple instances of this):

4.Yellow dot:

5.Yellow 'house' thingie icon(Usually pops up at around 80ish % scan:

6.Green dot: 100% scan. I can warp to.



Reason for this post is, that my signatures somehow disappear from scan, even though I'm certain to have a probe 'bubble' covering it.

Let's say I have a 4AU probe bubble hitting a sig. It tells me that there s sig within a 1AU sphere (I'm guessing that's what the red sphere means). I then lower the scan strength on my 6 scan probes, by setting them at 2AU. I then completely cover the red sphere. I scan and then nothing!

It's starting to annoy the hell out of me :(

Thx for any help.

The reason is scan deviation. The red marks you see might not represent very accurately where the anom is.

I usually have 4 probes narrowing the search with a 5th "overview" probe at a larger radius just to make sure I don't lose the signal when I zoom in.

Usually not a problem if you don't try to skip radiuses, but sometimes you'l get unlucky.

I use 7 probes, sisters of course.
One in the middle, 4 around it and 1 at top and bottom.

It's all about getting familiar with signatures and sometimes it gets down to a 50-50 chance of hitting right and in other occasions it's about skills and experience.

Firstly train the deviation skill for probing up a few notches, it'll help a lot including the one for strength.
Red sphere is basically that, I'll make sure the core center of my probe setup overlaps the whole sphere and scan it down.
Red circle is usually an indicator for "you have to move your probes up, down, left or right - without changing the radius (depends how big the circle is)". Sometimes this will indicate a signature that is far away from celestials if your probes are centered around a planet. When it does that you just gotta follow what it says and move your probes accordingly.

Two sets of red dots will require you to make an educated guess. It's either there or here. Where are you probes positioned? If one of the red dots is quite close to the center of your setup, but with a low scan strength it's probably not that one or else you would've gotten scan strength higher. This is the 50-50 guess.

In systems with many signatures I tend to circle through all celestials with the setup at 4 au. It'll uncover much signatures (making them yellow so you know what type it is) and then you can decide whether that's what you are looking for or not. Wormholes usually tend to be the signatures farthest away from celestials in w-space. Hence I run with 8-au when searching for a specific wormhole, but then I would use deep space probes as well to narrow the search.

Scanning is great, sometimes I'd do it for hours a day scanning through 20+ wormhole systems. Big smile

Excluding deviation:

Red sphere means the signature is somewhere on the surface of the sphere

Red ring means its on some point of the ring

Two dots means its at one of them (the other is a false hit)

Dots mean its at that point

So when you get a result, the signature will be at a point on the sphere's surface / ring / point, plus deviation in all 3 dimensions.

Basically each probe will get an approximate distance of the signature. If you use one probe, you'll get the distance of the signature from the probe, therefore it's at x distance in any position, so it's on the surface of a sphere with the probe at the center. When you have two probes finding a signature, it's the intersection of these two spheres, which forms a ring, and so forth.

P.S.: For suddenly disappearing signatures, check the Filters setting of your Scan Window, make sure everything under Cosmic Signatures is ticked on

If you don't have the sigs checked in filters they will disappear at 25%....

I have not been doing this for long but I have gotten not-so-bad at it and gained much profit - so I will put in my .02 ISK.

Keep track of the signal strength percentage and how much it has changed before deciding whether to A: Narrow the scan radius, or B: Move your probes to a better position.

If you have a scan result at 2% on the first scan, move your probes, narrow the radius, then get another result at 1.8% - thats a bad result, so opt for re-positioning your probes and leave the scan radius the same. If the next result jumps up to say, 5% - then that's a good scan, you may now re-position AND decrease the scan radius.

Sometimes a larger scan radius is better when signature strength is not getting any stronger.

Also, if you see me in-system, I'm treasure hunting - you should just leave!

j/k :)

Oh I gotta disagree with that - the dot is good and and you can center your probes on that point if you like, but it is only an estimated position and the site is somewhere in the direction of the dot.

Check the section - 'The scanning process' - for info about the Dots, Circles, etc.



By the way, the 'house thingie icon' is just a replacement icon for dots.

CCP first had signatures showing as dots, then changed all of them to show as Beacon marker icons. Now CCP has mixed the icons up so that Red is a dot while Yellow and Green are Beacon markers.
