It works as expected but it has to be attached to your windshield and range could be better. The more expensive ones you can keep elsewhere in the car and they still work.I just wanted to post an update and an initial review of the Whistler CR85. I JUST bought the lastest version of the Pro 78se in early July. If anyone here lives/travels through Atlanta, GA, they will know GSP is out almost every day in the metro area as well as other county and city police (Dekalb, Atlanta, Cobb, Doraville, Gwinnett, and etc). The terrain on both street and highway is VERY hilly and full of curves. There is also the potential for TONS of falsing due to Alanta being a high-tech city. There isn't much flat straight areas here unless you're heading out to the country or on your way out/in of Georgia. All these LEOs use the most sneaky cop traps and latest LIDAR and radar tools out there. The virtually NEVER use Constant On, only Instant On Radar Pulses and are sneaky with their lidar shots as well. If there's an environment where you have the LEAST warning to radar or lidar, it's ATLANTA! Virtually ALL of the LEOs here use LIDAR unless you're out in the country or there are multiple LEOs lined up for a speed trap. There are tons of Motorcycles, Dodge Chargers, Crown Vics, Tahoes, and you name it used on a REGULAR basis. If there's a town you're gonna get caught speeding in, it's DEFINITELY Atlanta!With this being said, I have looked all over for a real world review on the new Whistler CR series and couldn't find one. I had done my research and was impressed with the latest Pro 78se and thought there wouldn't be much difference between the Pro78se and the CR85. WRONG! I already bought my wife a CR85 and got to test both (the CR85 and Pro 78se) out in her car. At first, with the same settings, it didn't really seem like much of a difference between the 2 until I had a few encounters. Anyhow, here's the difference in cliffnotes: Settings for BOTH detectors were: X-band OFF, K-band ON, Ka-MAX ID, LSRID, Highway, Pop OFF, SWS ON, TFSR ON, Filter (the default setting), and a few others that shouldn't affect your detection. The BIGGEST difference is the CR85 really does catch ALL the new laser guns! I had both detectors mounted up high just under the tint strip on opposite sides of the rearview mirror about a 12 inches apart (CR85 hardwired) and tested for falsing with this setup vs only one detector on at a time. Both are very quiet here with TFSR ON (a MUST in Atlanta), but the CR85 has additional filter settings if you want that the Pro78se doesn't have (but I don't need to use them since neither falses much at all ever here). I didn't really see any differences with the exception of one KNOWN K-band false alert at a Kaiser Permanente parking lot I frequently pass (meaning I got a false alert while both detectors were on that I normally don't get at all on either by themselves).The CR85 consistently had AT LEAST a 5 seconds alert head-start traveling 65-70mph = (500-750 feet or so give or take???) over the Pro 78se (lastest version remember so older Pro 78se's will be even slower). The CR85 is also a BEAST with detecting LASER (LIDAR)! I was in the left lane doing 65 mph during moderate traffic and picked up on a GSP shooting laser OFF AXIS (in a slight curve), at the bottom of a hill facing forward (direction of travel) sitting in an exit gore on the right. I got a laser detection at least 0.5 miles back (completely out of sight) give or take, and what makes it so bad, the Pro78se NEVER alerted to it at all. I had PLENTY of time to slow down even if I was doing over 100mph. Of course in Atlanta, you virtually ALWAYS have a rabbit, so that was the tip off to the laser but this was a sneaky trap! Had I been speeding, with the Pro78se I would have been caught! Mind you I've been by dozens of LEOs here with it and it virtually never goes off to lidar (they must be using Laser Ally, Truspeed S, Prolaser III's, etc) and if it does, a blind person would have seen the LEO before the Pro78se went off lol. This is NOT the case with the CR85, it's a BEAST with picking up LIDAR! I had this happen multiple times so far with similar conditions.Anyhow, I actually feel safe with the CR85's lidar detection with a rabbit or 2 and using your brain of course. I was considering a laser jammer before I saw how well the CR85 has picked up LIDAR! Yes it's THAT GOOD! I didn't discuss K-band and Ka-Band detection much because it's not used much here on the interstates in the metro area, but I can tell you both K and Ka-band detection is GREATLY improved on the CR85 meaning MUCH MORE range and heads-up! Both the Pro78se and CR85 picked up on all K and Ka-band LEOs showing the same ID numbers from what I can remember. The difference between the 2 was so great that my wife told me to pull the trigger on another CR85 for myself which should be here tomorrow lol.Works extremely well in terms of accuracy and overall detection. It’s easy to screen out false signals because in East Tennessee it’s almost ALWAYS Ka band in use, but if you’re passing by the grocery store or mall where there’s lots of automatic doors the K band pops up. Always the K band.I live just 30 miles from the Virginia border. I frequently find myself in that state for a number of reasons. The VG2 setting is a bit vexing because when it sounds that there’s a radar detector detector in use, it does NOT also signal the presence of radar. But if there’s VG2 in use that means that there’s law enforcement operating it in close proximity to you. So…But the thing that is most disappointing is that it’s NOT self sustaining on internal battery power. I’m using it in a Polaris Slingshot and it’s a long reach to a power source, requiring a pretty long cord.Having portable power, internal to the unit that will hold a charge for even a couple or three hours would be a huge benefit to me.But the price cannot be beat for what you do get, even without internal power. It’s a GREAT unit, I just wish I didn’t have to fiddle with power cords. The voice warning is excellent too. The Slingshot is open and can be loud especially when the stereo is on. The voice will cut through that. I’m not using the provided mount. I put Velcro on the bottom and then I put a couple of different patches around the cockpit to allow for a more discreet mount point. It’s just a real pain to rig the extended power cord to support the more remote (what I call the Virginia) mount. I have not had any alerts with X or Laser, but on “power up” the device does show a sample alert with a very distinct tone.After reading the menu and setting up the device I observed the following :-Did not recognise fixed speed camera position, mobile camera positions, only gave a radar warning when directly under a variable speed camera, and if that wasn't enough, the KA band would sound at most school crossings and traffic lights. completely useless.Easy to useFirst I have to say I'm a noob when it comes to radar detectors. Never owned one before.The device was a pretty much plug and play. It does have a lot of options to change in the CR93 which is the one I got. I used it in city and highway in Canada and it did do it's job. How ever I'm taking this to Iran and I hope it work there.Build quality though.......... it looks fine when you look at it and touch it but my speakers sound not so good. They have a scratchy sound.5 alarms will go off but...The only one that matters is when ‘LASER’ is detected.... by that time... it’s already TOO LATE!!!!The police officer has already tagged you.It works and has detected photo radar police cars for me, by default I feel TFSR should be on, currently it's off so out of the box this device is very annoying and requires reading the owners manual and navigating the menu to make it more liveable otherwise you will likely throw it out the window
