How to Find Out what Radar Bands, Radar Guns, and Laser Guns are used in your area

In different parts of the country they use different radar guns and laser guns. For example, in some areas K band is in use while in other areas it’s not at all and if you turn K band off in your detector, you can get rid of all the false alerts that you’d have to otherwise deal with. Very cool. Same thing with X band. Additionally, some places in the country use newer and more sophisticated lidar guns with anti-jamming technology. If you’re wondering what’s in use in your area as well as in other areas that you’ll be driving to, here’s the best way I’ve found to see what’s in use in what areas.

Basically, check out the RDFGS.

It’s a user generated database where people across the country can add information to. You can go in and check down what’s in use in every state as well as what’s in use in different cities and counties. If there’s any information missing or out of date, you can go in and fill in the gaps and update the database accordingly. Very useful stuff!

Go ahead and take a look at the RDFGS and see what’s in use where you live.

Pretty simple and straightforward, isn’t it?

You’ll notice the map on the RDFGS is color coded to help you determine where radar detectors and laser jammers are legal or illegal.

If you scroll down, you’ll get an idea of generally what’s in use in different states.

If you click on a state, you’ll be able to drill down and see what’s in use in different cities and counties.

Here’s a few tips and tricks on how to use it and what to look for.

Obviously you’ll want to take a look at the cities and counties that you’ll be driving through. Out here in Washington State, the highway is monitored by the Washington State Patrol and so if you look at the top of the chart, you’ll see information about the State Police that’s worth checking out in addition to what’s covered for the individual cities and counties.

The green box for TSR will tell you whether or not K band traffic sensors are in use on the highway and if you should enable TSR/TMF to filter those sensors out.

The notes on the right hand side are great for finding out fun little tidbits like what lidar guns are in use in that area, what types of police cars are used, what frequencies of Ka (33.8? 34.7? 35.5?) are in use, and so on.

The information presented on the RDFGS is not necessarily accurate. The X band info is a perfect example. X band is almost completely entirely phased out (with a few exceptions such as OH, NJ, and some places in OR) and yet the RDFGS says that X band is in use in 24 states. This isn’t true. If anyone clicked on X band at some point, even if it was a mistake and they didn’t confirm that the X band alert was indeed coming from a police officer, now we’ve got some erroneous information.

It’s also tough to know when to delete information that someone else had posted. If someone sees that a radar or laser gun is in use and then later the agency upgrades to newer equipment and retires their older equipment, we may not necessarily know that and so the information on the RDFGS may become out of date. Some radar or laser guns may be used very very rarely so it’s hard to know whether or not the equipment is gone altogether or just that it hasn’t been seen in a while.

Only Intermediate+ members of RDF can edit the RDFGS. This way we can ensure that not just anyone edits it and the people working on the database have an understanding of radar and laser in general to keep it filled with quality information.

If you’d like to update the database, you can hop on to this thread, let people know what you know, and they can update the database accordingly.

      It’s a user generated map created by people like you and some smaller cities may not be there, but some neighboring cities might. You can drive around, get familiar with what’s in use there, and then help contribute for your area by posting here: https://www.rdforum.org/showthread.php?t=9980
