&lt;br /&gt;
A sonar unit combined with passive, air-density sensors,&lt;br /&gt;
the Motion Tracker is a hand-held motion sensor, which&lt;br /&gt;
provides the user with information about unseen&lt;br /&gt;
opponents. A Character must have the Computer skill to&lt;br /&gt;
operate a Motion Tracker and requires a Displaying&lt;br /&gt;
Information skill check. The device is operated by a&lt;br /&gt;
trigger mounted in the handgrip; thus, when not in active&lt;br /&gt;
use the Motion Tracker cannot be left on, conserving&lt;br /&gt;
battery power and decreasing the possibility that the&lt;br /&gt;
Motion Tracker, itself, is detected.&lt;br /&gt;
&lt;br /&gt;
[[File:MotionTrackerDisplay.png|right|300px]]&lt;br /&gt;
The location of detected movement is displayed on an LCD&lt;br /&gt;
screen mounted on the top of the device as a set of&lt;br /&gt;
probability contours ranging from black to white; black&lt;br /&gt;
indicating no movement and white indicating a high&lt;br /&gt;
probability of the location of movement. An auditory cue is&lt;br /&gt;
also provided in the form of a reverberating tone that&lt;br /&gt;
changes in pitch and reverb speed, based on the size and&lt;br /&gt;
proximity. A Motion Tracker will indicate the position, size&lt;br /&gt;
and speed of any object within its range.&lt;br /&gt;
&lt;br /&gt;
In ideal conditions (i.e., open terrain with no wind), the&lt;br /&gt;
Motion Tracker can scan accurately up to a kilometer,&lt;br /&gt;
however in buildings (such as the average, Frontier&lt;br /&gt;
building with metal and synthesized walls which to a&lt;br /&gt;
great extent, absorb the sonar bursts and returns), the&lt;br /&gt;
effect range drops to 30 meters. The size of object the&lt;br /&gt;
Motion Tracker is scanning for is determined by the&lt;br /&gt;
user, down to a minimum diameter of about 60cm. The&lt;br /&gt;
frequency and settings must be adjusted repeatedly to&lt;br /&gt;
filter interference and operating the Motion Tracker in&lt;br /&gt;
cluttered terrain is difficult without a good Computer&lt;br /&gt;
skill. The Motion Tracker will not work in a vacuum.&lt;br /&gt;
&lt;br /&gt;
The Motion Tracker can register movement on the far&lt;br /&gt;
side of a solid obstacle, but the air flow between the&lt;br /&gt;
two locations must be unblocked and the operator’s&lt;br /&gt;
task is made more difficult. For each corner or&lt;br /&gt;
intervening obstacle, reduce the operator’s Displaying&lt;br /&gt;
Information skill check by minus 10; one corner is&lt;br /&gt;
minus 10, two corners is minus 20 and so on.&lt;br /&gt;
&lt;br /&gt;
If the operator uses a Motion Tracker successfully, then&lt;br /&gt;
he or she receives accurate information regarding the&lt;br /&gt;
number, position speed and size of all moving objects&lt;br /&gt;
within the Tracker’s range; if the roll is failed, then the&lt;br /&gt;
information will be inaccurate to some degree. If the&lt;br /&gt;
roll is failed by 10 or less, the Tracker will show the&lt;br /&gt;
range and speed to all nearby targets, but the number&lt;br /&gt;
and size of the targets will be unknown. If the result is&lt;br /&gt;
failed by 20 or less, only the range will be known. If&lt;br /&gt;
the roll fails by 30 or less, the operator receives no&lt;br /&gt;
significant information. If the operator fails by more&lt;br /&gt;
than half, the Referee should give the operator&lt;br /&gt;
significantly incorrect information.&lt;br /&gt;
&lt;br /&gt;
The device does have problems, however:&lt;br /&gt;
* First, because the tracker emits high-frequency, sonar bursts it can be easily detected by passive listening stations as a target for enemy fire or by cybernetic, sound enhancers.&lt;br /&gt;
* Second the Motion Tracker is designed to filter out slight, “natural” movement, such as insects or flags blowing, so a very slow target may be able to infiltrate a Motion Tracker’s scan area.&lt;br /&gt;
* Third, because the Tracker uses air-density sensors (Doppler radar) to discriminate between immobile objects and targets, a target moving across the Tracker’s scanning cone may be effectively invisible. Finally, the unit is vulnerable to ultrasound jamming.&lt;br /&gt;
&lt;br /&gt;
The Motion Tracker uses a standard, power clip and&lt;br /&gt;
provides the device power, for up to 48 hours of&lt;br /&gt;
continuous use. The clip can be replaced in one turn.&lt;br /&gt;
The device is available at many high tech worlds&lt;br /&gt;
without a license (it could be used for hunting). It&lt;br /&gt;
costs '''500Cr''' and weighs '''1kg'''.&lt;/div&gt;</summary>
