Multi, Dual, Triple, ...
I feel that these terms are STUPID marketing terms. Dual trunking SHOULD mean that it can track two separate trunks at the same time. Unfortunately that is not the case.
My PRO-92 is called "Multi-System Trunking". It can receive Motorola (type I, type II & type I/II hybrid), EDACS and LTR type trunks.
As someone else wrote, our PRO-95s are called "Dual Trunking" and the manual states: "Simultaneous Trunking Operation — tracks two trunking systems (Motorola and EDACS) and conventional systems at the same time."
The PRO-97 is a "Triple Trunking" scanner; as like the '92 it does LTR.
