"Alright.  Now, as you know, you were all given these metal bracelets.  Well, they actually contain a multitude of different devices to assist in the capture of ghosts.  However, there will be three functions you'll be using more than any other, which are what I'll go over now." Zack said, hitting some buttons on his bracelet.  "First, is the GPS feature, which contains a map of Amity Park and several markers, each representing one of you, and one for Fenton Works so no matter where you are in the city, you'll know where the others are, and how to get back here.  Also, it'll allow Jaz to keep track of you guys and send you locations of ghost sightings from her tech setup here.  The second function is a communication device, so you can keep in contact with eachother, and Jaz can call upon you if there is a ghost sighting as well as keep you updated.  I must note though, that since the Ghost Zone is so vast and mostly unexplored, the GPS function does not work in there."
