I use 4 996P2 scanners that work quite well. I can get a 536HP for a song but other than zip code scanning what else would make it worth getting?
I program with ProScan and have favorites already built, as I program the scanners at work!
The built in database, and the ability to use it, along with a GPS, is an advantage for the 536 over the 996P2, and the other DMA scanners. This is very useful when traveling in areas you are not familiar with.
The P2 scanners, with the paid upgrades, can handle DMR & NXDN systems. But as
Ubbe noted, the 996P2 and it's hand-held sibling the 325P2, do not have the LCN finder which is available on the x36HP & SDS series scanners. The LCN finder is very useful in trying to nail down the multiple DMR business band systems in use here in the DFW area. For systems already documented in the database, the 996 can be programmed to monitor them. But if it is a new, not yet documented system, the P2 scanners do not have access to the LCN finder utility.
While the 996P2 has a very large memory, you're constrained when trying to have several different programming files. Your option is to split them up via start-up keys, if you want to switch programming for a different area or a specific working incident. The database scanners, including the 536HP, have the ability to have multiple different programming files (Favorites lists) available, and accessible with only a few key presses.
