All About Police Scanners
What are scanners?
A scanner is a radio receiver that checks ("scans") many channels quickly to allow you to listen to two-way radio calls. Two-way radios, used by police, fire and others, use short transmissions that occur on thousands of radio channels.
There are many different types of scanners and it can get kind of confusing to decide the right one for you. Fortunately the experts at Scanner Master can help you decide.
Another thing to remember is that once you buy a scanner you can learn more about how to use it as you go. Get the basics down now and learn about the more advanced features later if you wish. Whether the police scanner is for yourself, a relative or friend, the great thing about scanners is that you can use them at a basic level just to listen to your local agencies or one can immerse him or herself in the details of the scanner features and in the hobby and exploration of radio itself. A police scanner can be simply interesting and informative, entertaining or even provide you with a lifetime hobby if you so desire.
There are several factors to consider when picking the right scanner. We have boiled it down to 3 questions to simplify your choice:
How to Choose the Right Scanner
There are several factors to consider when choosing the right police scanner. To simplify the process, we’ve broken it down into three key questions:
Form Factor
Where and how do you plan to use your scanner?
- Base/Desktop Scanners – Ideal for home or office use with larger displays and better audio
- Handheld (Portable) Scanners – Take them anywhere for on-the-go listening
- Mobile Scanners – Designed for installation in your vehicle
Choosing the right form factor depends on whether you want portability, convenience, or a permanent setup.
Type (Analog vs. Digital)
What kind of communications do you want to monitor?
Public safety agencies use a variety of radio systems, including analog, digital (P25), trunked, and conventional systems. Many areas today use digital trunked systems, which require more advanced scanners.
If you’re unsure what your local agencies use, don’t worry—we can help. Just call or email us and we’ll look it up for you. Choosing the correct type ensures your scanner will work properly in your area and receive the channels you want.
Features & Ease of Use
How simple or advanced do you want your scanner to be?
Today’s scanners offer a range of features to match your experience level:
- ZIP Code Programming – Enter your ZIP code and the scanner automatically loads local channels from a built-in database
- Manual Programming – Traditional keypad entry for full control
- Computer Programming – Easily program and customize using software
Many models offer a combination of these options, so you can start simple and explore more advanced features over time. Whether you’re a beginner looking for plug-and-play convenience or an experienced user wanting full control, there’s a scanner that fits your needs.
Why do I want or need a scanner?
Most people who buy a scanner do so to hear what is happening around them. They want to listen to their local police, fire, and EMS departments and stay informed about activity in their neighborhoods. For many, it’s about awareness and peace of mind, knowing what’s going on in real time without relying on delayed news or social media updates.
Other scanner users have a professional need. Police officers and firefighters often monitor their own agencies when off duty and neighboring departments while on the job. Tow truck operators rely on scanners to respond quickly to accidents, while security personnel use them to stay alert to activity in their coverage areas.
In today’s world, scanners have become even more valuable for real-time information and emergency preparedness. Modern digital scanners can monitor a wide range of communications, including public safety, weather alerts, transportation, and local government channels. With many agencies now using advanced systems like P25 digital radio, today’s scanners are more powerful than ever, giving you direct access to live, unfiltered information when it matters most. Whether you’re tracking severe weather, traffic incidents, or community events, a scanner helps you stay informed, prepared, and connected to your local area.
What can I listen to?
Most people who buy scanners want to listen to their local police and fire calls. While they are often called "Police Scanners", there is a lot more to listen to if you want. Here is a selection of other users you could listen to on a scanner (depending on your proximity to the agency and the power and type of radio system they are using):
- Police (Local Police, County Sheriff, State Police and Highway Patrol)
- Fire Departments
- EMS/Rescue Squads/Hospital
- Road and Street Departments
- Railroads
- Air Traffic Control
- Military
- Schools and Universities
- Utilities (Water, Gas, Electric etc.)
- Malls and stores
- Stadiums
How do I get started?
That's where Scanner Master comes in. We not only sell scanners and accessories, but we also help you get going.
First we make sure you get the right scanner. We pride ourselves in helping our customers choose and use the right scanners for nearly 40 years. We have scanner experts on staff to assist. None of the huge online retailers can do that.
Second we help you setup your scanner. Scanners need to be properly programmed for the area in which they'll be used and "ZIP Code" scanners need to have the database updated from time to time. We can help you with these or you can do it yourself.
Finally, we are there to help when you need us. Once you buy from us we don't abandon you. We can help answer questions or at least point you to resources that you can use. Need a new antenna or software or just have a question? Call or email us!
