I'm guessing that you got a Pro-92, not a Pro-29. It is an analog trunktracking scanner. Nova Scotia uses a combination of analog and digital TGID's. NS fire is on analog TG's, police are digital. Probably the least expensive scanner would be the Pro-96/2096. It would receive the digital TG's. Better would be to get the RS Pro-106/197, or similar scanners.
