What is the difference? Im looking for a new handheld and seen double and triple tracking whats the difference i understand a bit what trunking is frequency groups that are shared but is there a huge difference between double and triple? I have a friend that just has top have my old scanner hes nailing me with email everyday so I may sell it to him and just buy a new one I had this handheld since the mid 1990s so Ill get a new one I dont care.
