The Pro-92 has lots of nice features (like alpha tagging), but from a strictly performance standpoint, its sensitivity at 800 mHz is terrible compared to many other portable scanners. I live about 5 air miles from our local EDACS system and my Pro-92A is useless. It misses about 80% of the calls while my Pro-94 misses nothing....and this is with the RS 800 mHz rubber duckie antenna on both of them. At my office, however, which is about a mile from the EDACS site, the Pro-92A works fine....so I only use it at my office. Another thing about the Pro-92 I don't like, as mentioned above, it does have one of the SLOWEST SCAN rates out there. This contributes to missing calls on a busy system.
