The motion tracker is not a radar, however, and can be subverted through slow movement, which makes you undetectable on other player's sensors. Crouching is the most effective method of Motion Sensor evasion, as it allows one to move at the maximum speed that lies beneath the threshold of detection, at least until you fire your weapon.
- The rats in Crow's Nest show up as small Infection Form-like yellow blips on your motion sensor, indicating that they are allied to you, or to avoid confusion about enemies in the area.
- The fish in Sierra 117 in the river where Johnson's Pelican is shot down and in The Covenant in the lake outside the first shield barrier control room show up as small Infection Form-like yellow blips on your motion sensor.
- The Hornets on The Storm and The Covenant—while you are on the ground—show up on your motion sensor as yellow blips, indicating that they can actually fight land enemy targets, but they don't. Strangely enough, the same does not go for the Banshees in any level. However, a blip on the motion sensor does not necessarily mean that unit can fight, either partially or completely. Surprisingly, the Banshees can be destroyed.
- In Halo 3 custom games or Forge, the motion sensor's range can be set to 10 meters, 25 meters, 50 meters or even 150 meters with blips becoming increasingly smaller the larger the range gets.
- In the novel Halo: Ghosts of Onyx, the motion tracker sensor is shown to be vulnerable to sea water, when Fred's motion tracker froze due to a crusting of sea salt.
- In Halo 2, if your shields are critical, your motion sensor will flicker on and off.
- Even if the player isn't crouching, if he/she is moving slowly enough, they will be invisible to the Motion Sensor.
- The yellow dot at the center of the Motion Sensor's display is the player himself. If the player isn't moving, this dot will disappear, then reappear once the player is moving with enough speed to register.
- Vehicles that are moving, but are not currently manned (i.e. If someone jumps out of a Warthog that keeps moving), will appear as manned by a friendly.
- In Halo: Reach, the motion sensor tells you in what area of the map you are currently in, as seen in the Multiplayer Trailer. The motion sensor is also 3D. Players below will show up as dark dots and players above will have a triangularly-shaped dot.
- In Prototype from Halo Legends, the HRUNTING/YGGDRASIL Mark I Prototype Exoskeleton was equipped with a 1400m+ sensor (with map mode).
- In Halo 2, if a player was to look up or down, the motion sensor "plane" will adjust to be perpendicular to the player view. (i.e. looking straight up will allow you to see how far someone is above/below you)
