Pinal County Sheriff should have completely moved off of their VHF channels. I don't know if they're being kept in reserve in the event of a trunked system failure.
Florence PD & FD's dispatch is conventional digital. I don't know if any of the other town channels are in use.
Coolidge PD & FD should be analog still.
I believe that DPS Metro South (460.275) covers as far south as Florence and Coolidge, but the troopers are usually on Metro East (460.200) due to dispatcher shortages, and the vast majority of comms will be in the East Valley of the Phoenix metro area on the 101, 202, and 60 freeways. Metro East Tac is 460.175.
DPS District 6 (460.025) will cover the rest of Pinal County. CI 5 (460.525) is also used in Pinal County.
Don't forget 460.225 for Statewide and State Tac.
