Tracker

"' We managed to get a tracker onto The Rake without it noticing. The signal reaches up to 125 studs. '""- Shopkeeper"

Summary
The device is used to track the Rake's movements. However, it has a limited radius of detection by 125 studs. This will only produce the "Bing" sound rapidly if the Rake is close to you.

The Tracker is extremely useless if you equipped the Night Vision Goggles as you can see the Rake from outside the limited range. It's useful if you don't have the Night Vision Goggles.

Trivia

 * The Tracker Model is actually designed by ROBLOX.
