I am thinking about purchasing a police scanner but can't decide which one would be best for my area. I mainly want it for police and fire and a small amount of aircraft( I am within 40 miles of 2 major airports and many small ones) And to listen to the local hospitals helicopter. I don't know much about scanners and am unsure if I need trunk tracking. I'm thinking about a GRE PSR-310 Triple Trunking Police Scanner as I found one local new for $170 ish. Also looked at a uniden BCT-8 for about the same price but I like a handheld. This will be hooked to an outdoor antenna when used as a base and I am only looking to receive maybe a 50 mile radius,Is this possible? This will never be used in a mobile but I would like to be able to take it to work to listen while working in the shop. Thanks in advance.
