UNIDEN R8 極端な長距離レーダー/レーザー検出器、方向矢印付きのデュアルアンテナフロント&リア検出、リアルタイムアラート付きGPS内蔵、音声アラート、レッドライトカメラ、スピードカメラアラート。

Radar is very good at what it does. There are plenty of false alerts (IN MY AREA, but it's good at filtering and isn't bothersome), however, it's very easy to distinguish a true positive with the way the radar picks up frequencies. There is room to tune this radar and minimize false alerts, though I haven't. I have yet to pick up Laser, but that's not the radar's fault, I just don't drive near the state line much. Overall: The radar does exactly what it's supposed to do better than it needs to. Super long-range signals, directional arrows are accurate, radar volume is easily adjustable with good ranges, and the mount is very strong. I do think that this can be overkill for most people, I purchased this one for two reasons, it is really long-range and it has future support for laser jammers. Otherwise, this is a very reliable and respectable radar. I'd recommend the Uniden R4 if this radar is to pricey.

***** DO NOT BUY THIS IF YOU ARE NOT IN THE USA OR CANADA ***** It does not work AT ALL. No detection in the UK or Europe AT ALL totally USELESS

The R8 is the 1st radar detector I've bought in about 10 years. The last being an Escort- that I believe was the first advertised undetectable radar detector. Driver STi, I think was the model name It was a GREAT detector for it's time, but over the years it became nearly unusable with all the false alarms it gave. Flash forward to this last week. It arrived on a Tuesday, it's Saturday morning now. 3 days of commuting to and from work in use. At the end of day 2 it had the GPS lockouts set. Perfectly. It's a 20 mile drive each way. About 4 miles are street traffic driving, the rest is interstate. Some YouTube reviews observed issues with the GPS lockouts feature. Maybe the firmware was updated for mine? IDK. But no issues with that whatsoever. Until I got the R8, I was - and still am- using the WAZE GPS navigation app.. WAZE is a fantastic app to notify drivers of road hazards and police presence in moderate to heavily trafficked streets and highways. But it's not that great in more remote areas or the wee morning hours for police alerts- or what if YOU are the 1at person to come across a freshly set radar trap? It's virtually useless then. That's where the R8 is worth it's weight 8n gold. UBIDEN engineered the R8 to have future Bluetooth connectivity to work with 3rd party app developers AND they are also working on a laser jammer add on device for the R8 as well.. Laser jammers aren't legal in all states. Do your homework on your area before you let that feature become a purchasing factor. In my area, X Band isn't used, so I turned that band off. I have it sweeping the entire K and Ka bands, including POP alerts. I keep it on the HIGHWAY mode. False alerts are very minimal and very shortlived. I suspect that the falses are coming from other cars using those bands for their own driver safety assistance features. There's filters for those band segments, but those alerts are weak and shortlived, I would rather have a hundred of those unobtrusive alerts than miss 1 real alert. I highly recommend watching the YouTube set up videos on the R8 and check out the recommended settings links that explain all the different settings use caaes to optimize your R8 experience. It really is a fantastic detector. I bought it through Amazon with the optional 3 year warranty. I don't expect problems with it, but you know the saying - Is rather have it and not need it than need it and not have it. Again, check out the YouTube reviews, they're spot on, but now with excellent GPS lockout performance, where that has apparently been an issue before. If you can afford it, get it. It's really all you need. Plug and play with a few minor tweaks, set it up once or twice and forget it. No app necessary.

This detector is high quality, has great performance and allows a lot of customization to dial it in best for your use case. My only gripe would be the mute memory stopped working properly for my normal commute after I took a 1,000 mile road trip. This is a known issue however, that should get fixed via software update, which you have to do manually by plugging it into your computer. However, after deleting the mute memory in the spots where it wasn’t working and re-adding them, it’s working well again. I especially like that there’s a 3rd party R8 companion app you can add to you smartphone for only $10 so you can more easily change settings from your phone. The app can also add more advanced false alert filtering and “Spot Locks” which are like Auto Mute Memory locations but overcome the memory glitch in the detector because they’re managed by the app. If you turn the volume of the detector off and run audio through the app, then most audio alerts should he real threats instead of the other way around, which keeps you sensitized to chirps. The only thing this detector want do much for is Laser detectors because by the time that narrow beam hits you it’s too late. The best protection for laser is a jammer. The best on the market is the ALP laser jammer and the Uniden R9 laser jammer, but the latter requires the Uniden R9 detector system instead of the R8. If you don’t want to shell out up to $2k for a legit laser jammer, then just keep a car or two in front of you. If the laser is far enough away, the beam will mostly hit them but can spread enough for you detector to detect.

We have this unit and hardwired in all of our vehicles with mirror mounts so we can move it between cars quick-connect style! Suggest everyone also use Waze to maximize risk mitigation. Best detector we’ve ever owned (25 years of trying and using all major brands). The R8 is amazing, we had a Valentine V1 prior. The R8 is aesthetically great, setup and configuration to our needs was simple, and it has not let us down in over a year. Wife’s new car is on the transporter, we’re planning on buying our second R8 to reduce the amount of swaps with do (we try to never drive without the R8)!
