	Nothing to do with energy. If I'm not mistaken, there's a separate stat unitref[062] that increments every time the unit walks, but not when other actions are performed. The amount it increments is based off the stat just before it in unitref[061]. Blip sizes are based off unitref[062]. -[[User:NKF\|NKF]]		Nothing to do with energy.

			As a pre-emptive clarification, it should be noted that although it seems energy would work as a mechanism for determining it(because the only time you use energy is walking), it wouldn't. While it is true that X-COM soldiers and HWPs only use energy when moving, some aliens ALSO use energy simply while turning in place (rotation). This is determined by another stat that determines at what level energy is depleted; some aliens lose energy at the same rate as TUs spent on movement. This can be tested with a Psi-Amp and a few psi-competent troopers, as well as a few extraterrestrial 'volunteers'.

			:: I generally get the most use out of a motion scanner with the Large Scout and the Terror Ship. With both of these, it's possible to get relatively close to the center of the ship without going inside...which is useful for detecting when sprinting is/has remained "safe", after clearing the outside. Alien Bases are a bit open for my taste.

			:: While theoretically possible, it's a bit harder to get effective use in: Farm, Terror, other large UFOs.

			:: And, generally...use all motion scanners in position <b>before</b> moving anyone else.

	The biggest problem with scanners is the false negatives: if you scan no movement, that either means there's no alien, or that there's one that's got all its TUs (''very'' dangerous).

			: That's its biggest limitation. It's only good in a "something's moving over there!" way. You otherwise can't be sure what ''is'' over there, except the alien that moved. About the best you can do is deal with it by readying an ambush (such as the case of a UFO assault - which you should already be doing automatically anyway so a scanner isn't necessary), before deploying from the Skyranger after waiting a few turns (about the only place I myself actively use it - it identifies movement beside or behind the ramp) or if you're in, say, the orchards or behind the grass hedges and you want to pinpoint the exact location of an alien you saw move into it. Mind you, a simple toss of a grenade is generally all you need to clear something like the orchards. Actually, alien bases and base defence scenarios are probably a good places to use it. Plenty of partitions and hallways, and in X-Com bases, you can have soldiers on the upper level or inside HWP closets scan the hallways to check if there's anything outside (and then get someone further down the hallway pop out and take it out).

	There might be cases where if you see a single "big dot" inside a UFO, it might be safe to enter since the alien will have used up most its TUs. I'm not confident this is a reliable indicator, however. I sometimes watch a dot from turn to turn to see which way it moves, which at least gives you some warning that an alien's probably on its way out.
