Jazzy, if you confront lidar on a regular basis, you're going to need to re-think your defense strategy.
Thanks. I have two cars, so
As everyone has said if you are facing lidar (and MD does use it) A RD is not the correct tool, the beam of a lidar gun may only be 1-2 feet wide at a distance of 1000ft and they are usually targeting low on the car so unless they happen to be aiming it just right your RD may not catch it. If it does happen to catch it, its going to alert and you will hit your brakes but it will be too late, the guns can get your speed in less than 1 second in many cases, by the time the RD goes off and you react and hit the brakes the officer will already have you at your original speed. The RD's main function is radar detection which you will want, cause radar is definitely used, for Laser you will want to look a ALP (antilaser priority) or TMG those systems can defend against the laser until you have slowed down. also realize that a lot of police will sit and just do paperwork or will be watching traffic for people weaving, using their phones, or whatnot and may not be using radar/laser so there may be nothing to pick up. Waze is a good option too as you can get alerts from drivers that are ahead of you about police. most folks here on RDF run a RD and waze as a minimum, many also add in ALP or TMG to cover laser traps that are not reported on waze. Do a little reading up here and feel free to ask questions if they arise.
Thank you so much for taking the time to explain. I will do my research on this site as to not take up any more time. You all have been a big help. I have two cars, so I was hoping to have something portable. But the WAZE idea is GREAT! I will get a good RD and use WAZE also. When I end up buying a new car, I will get an ALP. Thanks so much again!

Waze is a great tool to provide another layer of situation awareness!

Thanks. So what do most people do here about lasers? Spend $1k-$2k for good jammers? I just figured my DFR7 sucked and was going to spend $600 for a good RD with laser capability.
Laser protection is expensive, but just like with every countermeasure purchase, your first save or two pays for itself. Radar detectors are useless against laser. The only radar detector that has been said to give any kind of save toward laser is the V1, but that’s getting lucky and catching laser scatter from an officer targeting someone ahead of you. If the officer is targeting you, by the time your radar detector alerts “laser” you’ll be getting a ticket if you’re speeding.

Whether you spend $200 or $600 on a detector, it makes no difference when it comes to laser. You need a laser defense system to defeat laser. There are different options out there like ALP & TMG for example. ALP right now seems to be the better of the two but is more expensive than TMG. TMG is a great option as well though and they’re working hard to improve performance.

One way to save money is installing the system yourself, but if you’re not comfortable doing that, you’ll need to pay a professional to have it done. You’ll also want to get your system tested.

They are call radar detectors for a reason. They detect radar not cops or laser. Some of them will detect laser but they will only act as a ticket notifier. If you want protection against laser, your only option is a laser jammer.

Except for one small detail.... they are advertised as Radar Laser Detectors. While this does give a false sense of security, they are capable of detecting laser.

MSP seems to only use 35.5 with respect to radar. That's all I've run into, in the last two years. If you've never picked up 35.5 in months there maybe a problem with your detector. I've found they run radar a lot and see it daily, usually multiple times a day, but my daily commute is over 100 miles round trip.

As for Laser... it is what it is as others have stated and my R3 seems to pick it up ok. Last week, I had two confirmed laser warnings on my R3. But they were Harford County cops.

The nice thing is laser trap have to be stationary, so there is a better chance they will be on waze, radar can be used stationary and rolling so waze is not always helpful there, but your DFR7 if properly configured will deal with radar threats pretty well. just remember that Waze relies on other wazers ahead marking police, if there isn't much traffic, or at night there are going to be fewer wazers on the road marking things and at night cops can hide in the darkness and not get marked so adjust your driving speed a little under those conditions as waze coverage will be lower. when you do get a laser protection system you can always start off with just a dual head system and then add to it over time as money allows to make it bulletproof.

Many things are advertised to do things that they really don't. Look at Rocky Mountain.

Apples to Oranges. The fact is, the detectors CAN detect laser as advertised.

So as for the OP not picking up any radar. I checked the RDFGS and apparently both K and Ka are used in most of MD.

Have you ever had ANY radar alerts from the detector?

I definitely see 35.5 from MSP most of the time, much more than laser. I agree, if you haven't been seeing 35.5 at all from them there may be something wrong with your detector. Have you gone through the setup to make sure Ka band is enabled?

I have the Ka Filter off, but I will keep this one going and see if I pickup some Ka off the MSP. I have not passed any other officer (county ect.) in five months with this RD. I mainly travel freeway, hence why I always see MSP. I will keep my eye out for 35.5 when the Ka detection comes up. But I am dying for one with Arrows, so I think I am getting a new one anyway.

I do get several alerts. Just all bogus as far as I know. Don't ever see any officers when they go off. Usually passing cars. Both Ka and K.

I would just make sure Ka Band is ON, Ka Filter is OFF. Also, make sure you don't have a windshield or tint that interferes with radar (not common).

Where in MD are you traveling and not getting hits on 35.5?

Most of my freeway travel is on I95. I live in Cecil Co, but work down by Laurel, MD. I will admit there are days where I don't get hit with radar by MSP, but those days are rare. MSP also patrols Harford and Cecil counties a lot because we don't have a county police force like Baltimore. Sure we have the Sheriffs and the town cops, but out in the rural areas, I see more MSP... so I get 35.5 hits all the time. Last night when I was messing with my new R7, there was a rolling MSP that was running radar in the town of Bel Air. I never saw him, but depending on where he was turning or I was turning, my detector was ramping up and down.. sometimes a whiff... It was like playing a cat and mouse game. What I found strange last night was not seeing 34.7 from Hazard's (harford) Sheriffs on US 1. They almost always run radar just past the Bel Air bypass during the evening hours.

BTW, the arrows were nice because I was trying to locate that MSP cruiser.. Because on the R3, when I'm stationary, there's no way to tell if the radar source is front or rear. I was stuck at a lot of lights in Bel Air. LOL

I travel 100 and 97, which basically is AA County and Howard Co. Never get a Ka band signal. But I am going to check the filter and make sure it is OFF.
I got hit in Westminster on Thanksgiving weekend, which only has MSP as their police even on back roads, which is why I got this to begin with. But after it wasn't picking up MSP, I thought i had a crappy unit. I already have my hearts set on arrows. Just waiting to see how good Uniden's new one is verses Escort.

I am going to check at lunch. I have no tinting, so that isnt an issue.

I wouldn't wait that long ive seen many people day they'll get laser defense later and by that time all it took was ONE shot with lidar which resulted in the ticket and lawyers fees costing more than a quad Alp setup

But doesn't ALP need to be installed in the car? I have one sports car and one family car, both like 15 years old. Was hoping to eventually get a new sports car and install the ALP.

Define eventually? You're up against laser all the time. You cannot afford to speed because if they tag you once over their threshold you'll get a ticket

Yeah you have to install them for them to function properly, and get them tested to see if they in fact effective or a false sense of security. Stick around and you'll learn more as their is a wealth of information here once you get leveled up: The RDF Constitution (Forum Rules & Information)

You are absolutly correct. But I usually don't speed. But like anyone, I can zone out or get in a hurry and not pay attention. That is how I just got caught, for the first time in 10 years. Well, I got pulled over maybe three other times and got a warning. But I got a PBJ this time, and used up my last chance. I am just trying to keep from getting another. I, unlike most on this site, could probably be ok without protection. I joined today to get more knowledge as I was one that got false sense of security when I bought a DFR7 for "laser detection". Seems that although that is true, it is a stretch and will not fulfill my purpose. But $2k just to buy a ALP unit, let alone get it installed, need to save for that.

Everyone has their own budget and affordability scale. In the meantime, be aware and use what you have wisely.
