I almost purchased a Unication G5 Pager, but after exploring its capabilities I was not impressed. The limitations between the G5 and the SDS scanners do not even compare. If one system is all you want to monitor I guess its top-notch, but doesn't come close to what the SDS scanners can do. If I worked as a first responder or firefighter or police officer, the G5 would be nice to have as an off-duty radio to listen to my agency. But, if you are scanning multiple systems and searching out TGs, etc, a scanner is the way to go. IMO.
