If you already have a Pro-94, it will scan trunked systems well enough, except for the lack of LTR capbility. If you are looking to buy a scanner, the Pro-94 is not the one I'd pick. The Pro-97 is more sensitive, has text tags, CTCSS/DPL, and much better backlighting. The audio is better and the sceen is bigger. It will track any type of non-digital trunking system except the usual supects like ProVoice and OpenSky. However, if you need digital and want a portable, the Pro-96 is your only choice from RS.
