D-scanning

Hey guys,

I read some stuff about D-scanning, but I still don't really know what it is.
So what does it stand for? How do you do it? How is it useful?

Thanks!

It stands for Directional scanner, the other primary scan window besides the probe scanner.

It's called directional because the direction your camera is facing determines where it scans, unless you're set to s 360 radius, then it scans everything. Otherwise it scans in a cone beyond your ship of the selected angle. It cannot be used to warp to anything besides things you could always warp to without dscans (such as planets, stations, etc).

Usually used fro special awareness such as if someone is near a station or gate or not, or if they're close enough that they might be warp to you.

You will find tutorials on YouTube. You should watch them - it is immensely powerful. Don't forget your 'c' camera toggle which will align your camera and d-scan to whatever you click in space or on the overview.

And to just answer the first question that'll come up: no, you can't use it to pinpoint targets with and then warp to them (for that you need combat scanner probes). You CAN use it to deduce, kinda sorta, in which direction and at which range a target is. So you can use it defensively in a "anything uncloaked that gets within 14.3 AU will show up, giving me time to get the hell out" or offensively "hmm, the target seems to be in the belt/at the station/near the gate/in that anomaly".

And for the second question: No, it doesn't work automatically, you have to manually hit the scan every time. For defensive work that means that if you suspect problems to come your way you'll need to use that thing every 2 seconds.

Bonus answer: It uses the same filters as your overview (if you enable it), so switch filters to see different things. It doesn't necessarily see everything though, no npc for instance.

There's two main ways to use the D-scanner.

I term them "defensive D-scanning" - using it to discern how much danger you are in from predatory players, and "offensive D-scanning" - used to discern the location of potential prey.

Youtube tutorials will teach both.

Trying not to repeat too much that's been said already, but you can adjust the range of the D-Scan up to a max of 14.3 AU. By lowering the distance of the D-Scan you can get a rough idea of what is happening. An example of that is if there are 8 scanner probes on you at a distance of 1 AU, it's a good bet someone is trying to find you.

You can control the total angles it scans relative where your camera is pointed using the slider from 5 to 360 degrees. At 360 degrees it scans all around you, at 5 degrees it scans a 5 degree pie with where your camera points at 2.5 degrees. An example of how this is used: you catch a ship on d-scan and you want to kill it. You can set the angle to something like 15 degrees and move your camera to different cosmic signatures, anomalies and asteroid belts. Once he appears on scan there is a very good chance he is in that spot.

It's a powerful tool with a lot more uses, learn how to use this bad boy pronto.

Idea of a d-scan is easy enough let say you have a target t 14,5AU range and a planet, POS and a belt in that order in direct line (lucky you).
So what you do is you drop "the cone" to 90 degrees and then start dropping range until your target disappears.
So from your OV you deduct the ranges for planets, moons (POS) and belts and after that it's should be somewhat obvious where your target is currently sitting.

However using your brains is often quicker then d-scanning the exact distance for example if in a wh there is a hauler and POS in scan it's usually 99,99% of the time sitting at the POS if it's a combat ship and there are wrecks in scan it's likely in one of the anomalies and you need to d-scan the exact one.

A very powerful use of the D-scanner, offensively primarily but sometimes useful defensively, is that if there is a planet at 5.4 AU away from you, to check 360 degrees at 5 AU and 5.8 AU.

Anyone that is on the 5.8AU scan and not on the 5AU is *probably* at a celestial associated with that planet - an asteroid belt, a station, a customs office, a Player Owned Starbase at a moon, or at the planet itself.

This is even better in factional warfare - if you see a Gallente Medium Complex at 5.3 AU, and there is a player ship that shows up at 5.4 but not at 5.2, they are almost certainly in that PLEX or waiting in ambush on its ingate.

Tip: center the camera tracking position and your ship in the center for the screen.

Here's a tutorial

So far everyone's mentioned using the tracking camera to center your view. There's another way that I use often though

Instead of using the space view, switch to solar system map mode. SInce 9/10 times players are at some specific place on the map like planets, sites, belts etc. this allows you to quickly visualize all the possible locations and see which ones are outside your range.

To perform the scan, double click on your own location to center your view (say you are at the sun for example). Then zoom in as far as you can and rotate your view to line it up with a planet. You can them use the sun like the scope on a gun; line it up by placing it directly on top of the planet. This allows you to easily do 15 and 5 degree scans without getting dizzy from the tracking camera swiveling your view around in space. I also feel it gives you a better visualization of where things are in respect to each other.

I use this method the vast majority of the time when hunting other players. It's especially effective for FW sites because they show up as beacons on the map. It's also great for locating POS in hostile systems. Start at the sun, and scan each planet for a forcefield. Once you find the planet, warp to it and use it to line up with the moons for a second round of scans.

D-Scan does NOT scan in the direction your ship is pointing. Your ship is a sphere with a position and a velocity vector - it doesn't "point" anywhere.
D-scan scans in the direction your camera is facing.

Not mentioned yet, but one application of d-scan is anchoring a control tower around a moon; first you have to find a free moon.

1. Set your overview (any tab) to show only planets, moons, and control towers.
2. Set your d-scan to filter by overview.
3. Sort your overview by distance [though honestly I sort by name for this].
4. Warp to planet 1 (a fast warping ship, even a shuttle, is best to use).
5. Set your d-scan to scan a range that is roughly furthest moon distance around this planet + 10,000 km (1 au = ~150,000,000 km).
6. Activate d-scan.
7. Count the towers on d-scan.
8. If number of towers = number of moons, warp to next planet, and repeat from step 5.
9. If number of towers < number of moons, there is a free moon around this planet!

10. Set the d-scan range to cover roughly half the moons around this planet.
11. Activate d-scan.
12. If number of towers = number of moons, the free moon is in the outer-half of moons around this planet.
13. If number of towers < number of moons, the free moon is in the inner-half of moons around this planet.
14. Either continue to use d-scan to find the free moon, or just start warping to each inner-half or outer-half moon and checking visually.

It takes less than 10 minutes to d-scan a system for a free moon.


There are many ways to use d-scan. Use your imagination and be creative. Example: I once used it to find a spot located between two celestials, by making a lot of bookmarks while in warp, and only keeping the one that was closest on d-scan to the target, and repeating until I reached the target (which was unprobeable).
