The Dream Probe is used to examine the remnants of one's dream by scanning their cortex for residual memory waves pertaining to their dream. The device then renders an image from one's dream as a projection using these memory waves. The stated factors of assessment are:
- Plastic cognitive projection
- Physiochemical resonance
- Psychoplasmatic evanescence aberration
In Season 2, the device debuts the function to scan matter and receive its data.
In Season 4, the device's holographic projection function is not limited to the rendering of dreams, as it can project a hologram of anything after receiving a data transmission, including pre-recorded messages. It is also used as a transportation device. Tecna refers to the teleportation function as "teleportation technomagic".
The Dream Probe is the palm-sized circular housing of a ladybug nanobot, which releases itself from the housing to scan a subject for certain aspects. The nanobot's wings have the colors of a traditional ladybug: red with black spots. The wings will sepeate to reveal a dark grey body. The nanobot has a light grey abdomen and six red legs. Occasionally during analysis, the nanobot will emit a light upon its subject.
The main body of the device has rings of red, orange, and gray, and five red buttons with black dots along the gray ring; four buttons on the left side and one button on the right side. A section of the gray ring extends beyond the previous two rings. The bottom of the device is orange. The circular lid is purple with orange trim. The inside housing consists of yellow circuit patterns with orange dots.
In Season 1, before analysis, the red ring connects the two sides with buttons on them. After analysis, the sides are not connected and the lid gains red and white dashes along with a gray and red semi-circle on the lower portion of it.
In Season 2, the device emits a green glow after analysis on one occasion.
In Season 3, there is an orange rectangle shape at the bottom of the lid that lights up yellow when a red button is pressed. A light emits from the bottom of the device indicating a scan. The side with four buttons is on the right and the side with one button is on the left. The red ring also connects the two sides with buttons on them.. The nanobot is absent in Season 3.
In Season 4, the device is directed toward the subject when a scan is being initiated or is in progress. The inside emits a blue glow upon being opened, scanning a subject, or after a subject has been successfully scanned. The device emits energy waves when projecting an image or scanning a subject. When an item is the subject of teleportation, the device scans the subject and sends it directly to the chosen location. The nanobot is absent in Season 4.
In "Betrayed!," Tecna uses the device to scan the remnants of Bloom's dream. During the analysis, Tecna informs Bloom of the possibility that the woman in her dream was trying to communicate with her through a psychomagic message. The device then projects an image of the woman into the air, helping Bloom to recall the rest of her dream.
In "A Trap for Fairies," upon entering a room full of witches in beds, Tecna uses the device to scan an unresponsive Rubis. She concludes that the seemingly sleeping witches of Cloud Tower are alive, just under a powerful spell that has put them in suspended animation.
In "The Fairy Hunters," Tecna uses the device to project the Specialists and Nabu into an Alfea hallway. Tecna then receives Timmy's transmission of Sky's message for Bloom and projects it as well. Later, Tecna uses the device to scan the box placed in Alice's backpack, which the device led her to after scanning the fireball residue in the training area. The box contained residue identical to that of the fireball used to sabotage the Winx's training session and inadvertently injure Flora. Tecna's analysis concludes that the fireballs are composed of 75% iridescent blasto-phsopherine.

- In the 4Kids version, the device is called Psychic Beetle or PB Bug.
- In the 4Kids version, the image the device projects is referred to as a "digisketch".
- In the 4Kids version, the device is able to detect that Aisha is the princess of Andros.
- In the Nickelodeon version, the device detects 95% nova-sarin in the residue of Clarice's fireball.
- Although Tecna stated the term "psychoplasmatic" as a factor of assessment, it is likely that the correct term is "psychoplasmic". Whether this was a script error or a blend of words to create a new term is unknown.
- The device has similarities with the Magic Watch.
- The Omni-Detector derives its name from the root "omni-": a combining form meaning “all,” used in the formation of compound words.
