SDS100 Uniden Police Scanner


This is—beyond a shadow of a doubt—the best scanner on the market and the one we recommend more than any other scanner.

Launched in June of 2018, it's the newest (we'd say shiniest, but it's flat black) digital handheld scanner on the market.

The SDS100 is fast, easy to use, has a customizable color interface, and simulcast monitoring capabilities that blow all the other digital scanners out of the water. Clever segue: it's waterproof(!) Uniden has set a new standard with the SDS100.

Will the SDS100 work in my area?

Software, programming, simulcast, digital...confusing right?

Don't worry, we'll help you find the perfect scanner for your area.

Our experts will research your unique area for free & tell you exactly which scanner(s) will work for you.

Why should I buy the SDS100?

The SDS100 is the best scanner on the market and the flagship scanner from the largest police scanner manufacturer in the world, Uniden.

The simulcast capabilities are one of a kind and you can buy add-ons for NXDN, DMR & ProVoice.

Basically, this scanner can pick up everything possible (barring encryption and private OpenSky systems) no matter where you live.

There are a plethora of features that make this the best scanner, but the big two are:

Everyone at Zip Scanners owns an SDS100 for personal use and, needless to say, we’re kinda into scanners. The SDS100 is flat-out unbeatable. We love it and we’re confident you will too. It’s a little more expensive than the competing manufacturer, Whistler, but a great investment if you want to be set for years to come.

What are software upgrades?

Software upgrades are a subset of digital modes of transmission that affect individual frequencies and, often, countywide trunking systems. If your area, or an individual frequency that you wish to monitor utilizes these modes of transmission, you must purchase the upgrade(s) associated with that county/talk group in order to monitor those broadcasts.

We can look this up for you here.

Upgrades can be made directly from Uniden, but we do not provide support on upgrades if we do not install them.

What's simulcast?

Check out this full explanation of simulcast. If your area is affected, you must purchase a simulcast capable scanner.

Will this come with the larger battery?

Yes. There was a smaller, weaker battery when the SDS100 launched in 2018, which has since been updated and replaced with a larger battery.

What do SDS100 buyers say?
  • Simulcast distortion monitoring works as advertised.
  • The SDS100 is 25-50% faster than the BCD436HP or TRX-1.
  • SD card placement is better than the BCD436HP.
  • The SDS100 is much more sensitive & can pick up weak signals from far away.
  • Able to charge & run at the same time, unlike the BCD436HP.
  • Customizable color screen is easier to see than the black & white BCD436HP display.
  • The stock antenna is just OK. Uniden degraded the antenna to get certified as waterproof. This on-set antenna increases range up to 100%.
  • If the knob (multi-function, volume/squelch scroll) is not functioning properly, pull the knob off & reattach.
  • New battery tends to get hot and doesn't consistently last 8 hours, as Uniden suggests.
Major SDS100 & BCD436HP differences?
  • The SDS100 can interpret simulcast distortion.
  • The SDS100 is 25-50% faster than the BCD436HP.
  • The screen on the SDS100 has color-customization & far superior resolution.
  • SDS100 is more sensitive & superior at picking up weak signal & "RF environments".
  • The SDS100 allows you to charge and monitor frequencies simultaneously. The BCD436HP must be powered down to charge.
  • The BCD436HP came out in 2013. The SDS100 in June 2018. Like most technology, there have been several drastic improvements and a few minor adjustments that make a world of difference.
Major SDS100 & Whistler TRX-1 differences?
  • The SDS100 can interpret simulcast distortion.
  • Whistler has pre-decoded ProVoice, DMR, NXDN on the TRX-1 at no extra charge; Uniden requires paid upgrades to decode these on the SDS100.

Looking to deeeep dive?

We took the time to scour the internet for you.

Deep dive on programming here.

We HIGHLY recommend letting our experts program your scanner.

Programming issues are, by FAR, the #1 reason for...

  • Returns
  • 99% of any negative comments about the SDS100 you'll read while researching
  • 99% of any negative comments about us
  • 90% + of all support questions
  • Our receding hairlines

Basically, you're about to spend hundreds of dollars on a snappy new gadget, might as well spring a few extra bucks so it will actually work right out of the box.

What is programming?

Scanners work like AM/FM radios in that they pick up airwaves based on a set of specifics frequencies. But unlike a radio there is not the simple 'seek' and 'save' feature on a scanner. Also, the frequencies are wildly different based on where you live and what you want to listen to.

What, specifically, do I get with expert programming?

For each county you purchase, our experts will program the following:

  • State police, fire & EMS
  • County police, fire & EMS

Add as many counties as you'd like.

When your scanner arrives, the programmed data will be on your scanner in easy to navigate lists.

What if your programming does not work?

100% money back guarantee on programming.

Can you program X, Y, Z?

We can program anything in Radio Reference, the world's largest & best frequency database. 

What if I need help after you program?

We’re always here to help with our lifetime tech support. 

Why should I buy programming?

Programming is the #1 reason police scanners are returned.

While scanner programming is much easier than the days of crystal scanners, there is a learning curve like any other electronics purchase. While some scanner enthusiasts are highly technical and want to learn the ins-and-outs of programming, others want their scanner to just "work" right out of the box.

95% of all scanner sales include programming, so unless you’re familiar with scanners, scanner terminology, own a PC (Macs do not work), and want to learn the nuances of programming, we highly recommend letting our experts program your scanner.

Scanner technology is fairly user friendly, but scanners are not smartphones or iPads. If you're spending hundreds on a scanner, we recommend springing a few extra bucks so it works right out of the box.

Can't you teach me programming with your lifetime technical support?


Lifetime technical support is not unlimited technical support. We made "how to" videos and can help point you in the right direction, but we will not teach programming.

How long does your expert programming take?

We usually get this out same day, but it can add 1-2 business days to your shipment.

Can I program this scanner myself?


We created a programming decision tree, as well as programming videos, to help you decide whether you should include expert programming with your scanner. With that said, we HIGHLY recommend adding the expert programming to your purchase to save time and spare yourself potential aneurysms.

Can't I just punch in my zip code for programming?

Yes, however...

When you punch in your zip code, it scans EVERYTHING in your area, which is kinda like getting the phone book thrown at you.

With our expert scanner programming, we filter out the junk so you don't have to listen to things such as the dog catcher, repo guy, power company & the like.

How long will it take me to program on my own?

It takes our scanner tech anywhere from 30 minutes to several hours to program each scanner...and this is ALL he does.

For new & moderate scanner users, we estimate 3-12 hours of programming. Setup time varies wildly based on scanner, area and general tech familiarity.

What software comes with my SDS100?

The Uniden SDS100 comes with Sentinel software like other Uniden scanners, including the:

While there is a version of Sentinel software for each scanner, they operate the same. The SDS100 includes Sentinel software (download free SDS100 software here). Watch our Uniden Sentinel software programming video here or above in the video gallery.

Any self-programming tips?

We recommend downloading the software before you buy to test drive.
