    With the R1 being so cheap atm, I'm tempted to grab one for rear detection. Does anyone have experience with this?

    Typically running two detectors in close proximity can affect performance Anything from falses, to reduced range, to locking up a detector in extreme cases.

    Not sure how much it will be affected when they're from to back on a longer car. General rule of thumb, it's not recommended. That being said, have fun experimenting and testing to find out for yourself

    Just finished running an R3 and V1 mounted 44 1/2 inches apart on opposite sides of the windshield for two days. Noticed no apparent issues, but this was not any sort of controlled test by any means. Try it but be careful initially with your speed. Would hate to find out my detectors are in LaLa Land especially doing PSL+30 like earlier this morning. Drive a route where you are familiar with speed trap locations and see if alerts are consistent with those you remember from before. YMMV

    I have ran 2 R1s in my SUV about 6-8 feet apart, one up front high left side of RVM and the other mounted and concelead on the rear hatch window and I have never experienced interference. This is based on known stationary sources that were picked up and alerted to at approximately the same location if I were running a R1 solo. Since KA is the primary threat in my area, I disabled X and K bands on the rear detector with automute set to 2 running in full dark mode. It’s the next best situational awareness concept outside of the V1 and 360, but with the upmost superior range. :)

    If I got hit from the back and depending on the distance of the radar source, the rear detector squawked full blast while the front detector would slowly ramp up as the source closed in. As the source passed or exited both detectors operated, gradual ramp up/down according to location of the source, in the same manner you’ll expect from a V1 or 360.

    Did you find it helpful/worth it?

    Yes I did. If you are seeking situational awareness and don’t mind running 2 detectors it’s defintely worth it. I did this only because I got tired of the R1 alerting to a source and not being able to know which direction it was coming from. R series pickup so far away and it’s off axis is stupendous that often you’ll get alerts and never see the source, better yet discern the source’s direction. I drive many miles a day on roads where troopers are notorious for sitting on the side of on-ramps parallel to passing traffic clocking unsuspecting cars from behind after they’ve past the ramp, or after you’ve gotten on to the main thru-way from a ramp they lurk up from behind you blended into oncoming traffic.

    This gave me a peace of mind and awareness on whether they were behind me as I boarded a main road, up ahead of me sitting on a ramp lying in wait or no threat sources that are way off axis where I simply proceed on based on the ramp up and down behavior of both detectors in unison. Once you run 2 you’ll start learning the behavior of how they work in unison based on the situations at hand. Once you have this down you’ll know immediately how to react.

    I ran ghetto arrows in a large SUV for a year with no noted issues, but they were pretty far apart and facing opposite directions, I would definitely not do it in a small car or with both of them on the front window. Interference is random, 90% of the time there will be no interference and they will work fine, the other 10% of the time they may go to sleep and you wont know it's happened until you are getting pulled over by a cop running Lazy C/O that you didn't get an alert to due to interference.

    That precisely correct....they must be ran in opposit directions.
