The HP-1 is not "dependent" on the database. The built in database is an extra, you don't even have to use it. You can enter systems, sites and frequencies manually just like any other scanner only it's a lot easier. Using Sentinel you create favorite lists and then either copy from the Sentinel database or enter the systems, sites and frequencies manually. Then download to the HP-1. I only use the "full database" zip code entry feature when I'm traveling out of my local area. Locally I select from my personal favorite lists, police, fire, business etc and it only scans the channels I want. I encourage anyone interested in the HP-1 to download Sentinel and try it out. You don;t have to have an HP-1 to learn how easy it is.
