The Guide Kit and its cousin the Guide Beacon Gun are support devices which have no offensive function on their own. They work in concert with weapons that lock on to targets, and are very powerful and useful devices if employed correctly. It should be noted that a Guide device does not increase the duration of the projectiles a weapon fires; while the above Guide Kit would allow a Wing Diver to lock on her Ghost Chaser weapon at 3,000 metres, since Ghost Chaser projectiles only last for two seconds it would still be useless against any target more than 200 metres away.
