One of the great features of the Uniden scanners is location control.
This is powerful, because you can turn on/off sites, departments and even trunkgroups using the scanner's location.
And, all the info in the Sentinel database is geo encoded.
By building favorite lists by location, you can use location control to your advantage.
Also, you can use a GPS 'puck' to do this automatically.
Of course, if you want to listen to all 150 at a single location, I suppose the above doesn't matter.
I'd still build separate favorites for stuff and assign quick keys in order to control what is being scanned.
