Hiya All,
Yes another scanning question.
Last night I was scanning down my first grav site and got it down to 0.25AU probe with a 76.84% chance - type even came up as Medium - Hedbergite (and other ores)..
I spent half and hour trying to get better than this and nothing worked.
What do I need to do to get a lock in these situations?
What I've got so far (correct me if I'm wrong on any of these) - Train Astrometric Rangefinding to L4 - Get PPF-0 plugin - reducing defiavtion of scans by 2% (or more?)
Further questions: Will using more than 4 probes help any to lock a site?
Since the Item Database Wiki only has the Old Skills (pre Apoc), what do the skills do that might help?
Thanks in advance.

the probes need to be laid out properly. to triangulate something in space with no fixed point of reference, you need four points of reference, minimum. length, width, depth and high.
imagine a triangular based pyramid, made of equilateral triangles. place one probe at each point, with the approximate location in the middle. shuffle them around a bit, until you find it.
if you want, you can stick a 5th probe in the mix, in which case imagine two of those pyramids with the bases pressed together, and once again one at each point with the sig in the middle.

Edited by: Bo''Tox on 21/05/2009 09:28:10 Thanks, but I've been doing that.
My question is: Would it help to use a Four base pyramid (5 probes in total), instead o fthe three base and one top/bottom probe to help triangulate the site down and get a little better results or does it give you NO benefit at all?

I believe there's a point at which the probes start to interfere with each other if their scan radii overlap; for example if you were to move the probes twice as close to the target you'd expect the hit quality to go up, but often it goes down. I find that with the hard-to-find targets, it's often a case of jiggling around the probe placements to find the optimal range; position the probe too far from the hit and it doesn't get a good enough strength to go to 100%, but position it too close and it interferes with the other nearby probes also causing the signal strength to go down.
I find what works best in practice is to have the probes just in range of the hit (so not overlapping each other), and then bring them all closer in in tiny, equidistant amounts until the hit is 100%. If the strength starts to go down, move them further away again or rebalance their distances.
Bear in mind that some difficult sites will simply not be findable with low/medium skills and unbonused ships, because you just cannot get a good enough hit. If you're scanning in a GCU-rigged covops with reasonable skills, you should be OK, but if you've just put a probe launcher on a generic ship then it's definitely feasible you'd have these issues, and you may not be able to resolve the site to a warpable hit in this situation.

Some sites are simply too hard to find with basic skills.
If you dont have them already, look into the following:
Covert Ops - 10% additional strength per skill level when using a covops ship
Astrometric Rangefinding (I think) - 10% scan strength
These alone can double the strength of your probes if they are fully trained... but they take a long time to train up to level 5 - look to get to level 3 as quick as you possibly can though.
You can also look to getting sisters scan probes, which have 10% addition strength over core probes/combat probes, but these are fairly expensive at around 1 million isk each (thankfully they arent destroyed anymore after use like in the old days)

Good comments here. The shape you want to have your probes in is called a ôReuleaux triangleö I believe. Most people agree that you will get a better signal using this pattern and receive less deviation (interference between probes) with the target located in the middle portion.
Astrometric Rangefinding: Skill for the advanced operation of long range scanners. 10% increase to probe strength per lvl.
Astrometric Pinpointing: Greater accuracy in hunting down targets found through scanning. Reduces maximum scan deviation by 10% per lvl.
I would take some time to train up some skills and keep at ità Hope this helps and GL M8
