Unfortunately the tool tips for the following powers are not very helpful and I'm not entirely sure they weren't accidentally copy / pasted. That being the case I thought I would ask the community for some elaboration on the similar but different powers.

Jam Sensors - Is this the one that in PVP causes them to disappear completely?
Jam Targeting Sensors - Is the the same as Scramble Sensors because the tool tips don't appear to be right?
Scramble Sensors - Essentially causes (all?) fire to redirected to the attackers ally.

With Scramble Sensors does this affect all types of fire? Does distance play into this at all? Through observation it appears to me that if no ally is within your firing arc you will continue to hit your target as expected. The only notable exception I have seen to this is torpedos which seem to seek someone out with a vengence. Is this the case?

Is Jam Targeting Sensors single target and Scramble Sensors AOE?

Thanks in advance.

There are only two powers, not three. Here goes.

Jam Sensors is an Ensign-base (1/2/3) skill. It simply removes you as a possible target for your foe. That foe might not have targeted you in the first place, in which case it does nothing, but if he WAS targeting you (very common when soloing) it might cause him to stop firing entirely. Note that it doesn't keep him from targeting your mines, assault shuttles, or certain heavy torpedoes (plasma or tricobalt), so if you use those skills often then it's not really worthwhile.
One plus is that it's an instantaneous attack; no flight time needed. The downside is that it's purely single-target and doesn't really help much in groups.
Short text: "Placate"

Scramble Sensors is a Lieutenant-base (2/3/4) skill. You fire the Happy Fun Ball, a small green sphere. Once it hits a target you see a big green burst, and the target will start sparkling. It's somewhat contagious; after a second or two, other nearby foes may or may not start sparkling as well. Any sparkling foe will pick a target hostile to you; they won't just retarget on your allies. Note that targetable torpedoes (plasma, tricobalt) and mines can also be infected and begin targeting each other; watching ten mines decide to attack the guy that just dropped them is kinda fun. If you kill the target before the ball gets there, nothing happens. Even if you wait for the target to be infected but you kill it before it has time to infect nearby foes, you lose that part of the effect as well.
So the plus is that it's great in groups, the downside is that it requires time to fly to the target.
Short text: "AoE Confuse"

The confusion is that Scramble Sensors I is listed as Jam Targeting Sensors in the short text. But the tooltip gives the correct name, and it's easy to tell purely based on rank.

The other power you might be confusing here is Mask Energy Signature, which is the "Cloak" power that makes your target disappear.

Ok that makes more sense Jam Targeting Sensors I is actually Scramble Sensors I then?

In PVP I had someone targeted in the far distance and I was looking at their ship center screen. They disappeared and I lost target and a few seconds later they were handing me my arse. I thought that was Jam Sensors and that Mask Energy signature just made you harder to pick up until you were in closer. Thanks for the clarification.

If you're fighting a single enemy, does Scramble Sensors still stop them from firing at you? I just picked it up, and I'm not sure yet if it does or not.

No, it does not.

In one-on-one fighting, Scramble does almost nothing at all. The only caveat on this is that if you hit a foe with it who's laid mines or fired a heavy (targetable) torpedo, he won't fire on his own mines or torp, but they won't track YOU, either. They'll sit there and wait for the duration to run out, giving you more time to zap them. But generally speaking, it's not worth the effort to use in this situation.

Scramble is at its best when there are many foes, regardless of how large your own group is. For fifteenish seconds the foes won't be firing at you, and WILL be firing at each other, so it's a win-win. It was so effective against the Borg that they've recently made the cubes scramble-proof, since a cube could rip apart the probes and even spheres that accompany it.

Jam is best in a one-on-one situation (since the opponent will have no valid targets at all unless you've laid mines), although it's also pretty handy when grouping against a single powerful target; if your flimsy escort gains the attention of the big Tactical Cube; you Jam him, and he'll start shooting at your cruiser teammate instead. If there are multiple foes then this won't do much, but against a single powerful target it's very good.

And both use the Sensors skill, even if they then diverge on Array/Probes. So it's easy to find a good deflector that boosts both.

Thanks!

Now I gotta figure out how to get Jam back.
