HP-1/Sentinel user since day 1.
Anybody feel free to correct me,but I have found absolutely no use for multiple profiles. Only usage I could see is if you are reaching a max amount of favorites or have so many it's hard to navigate.
Or you program multiple radios with different requirements or usage.
FWIW - I have 2 HP1 and use the same profile for both.
I personally like multiple profiles, but only if they could be stored and changed on the scanner without the need of the Sentinel software. Unfortunately, the HP-1 (and the the BCD536HP and BCD436HP) can only have one profile loaded at a time; while Sentinel can store multiple profiles on your computer, Sentinel (and thus a connected computer) must be used to change the profile on your scanner.
The V-Scanner method employed on the PSR-800 allows you to essentially change your profile without the use of an attached computer; that would be desirable on the Uniden scanners. (Note: I'm not saying the V-Scanner method is perfect; it too has limitations I don't care for.)
I have found over my many years of scanning with many different radios, that I operate my scanner (or scanners if I'm able to employ more than one at a time) in several different "Modes". I will generally operate with wide coverage to get a general sense of surrounding activity. When certain events happen, I'll often try to focus on that activity. While the capability to "Hold" on a System or Department is a great improvement over previous scanners, it often isn't adequate. I'd like to be able "rapidly" switch (i.e., only requiring limited key strokes and time) to a specific subset of the Systems/Services Types.
Having multiple profiles dynamically available on the scanner would allow me to switch modes more quickly as needed. While it can be argued I could accomplish much the same with multiple Favorites Lists, that approach also has limitations. Many of my "modes" would have overlapping systems and require a lot of duplication. While this is not a space issue, it is a data management issue; especially since systems in a user's Favorites List are not automatically updated.
I'll get off my soap-box,
Ted
