I believe only the redline 360c is RDD immune. The regular 360c can be detected hundreds of feet away. V1G2 is also immune. The Unidines vary from model to model and from unit to unit. Even though I had an RDD immune detector, I opted to put it in the glove box when in Virginia.

Honestly it sounds like your R3 is still serving you just fine. However, if you're comfortable without arrows (you've been rocking your R3 for some time) I'd actually recommend the R4. It's super compact and gets you the capabilities of the R8 (minus arrows) and arguably even better range in many cases.
Use it at your own risk. Uniden detectors are claimed to be RDD immune but in practice how immune depends on the individual unit not just the model. You can have two different R3s and one may be only detectable if you are a few feet from the officer where others could be detected a few hundred feet away.
The R3 has served me well too (No tickets since 2015). Upgraded to the R4. The R4 and R8 ranges are significantly improved and worth the investment.
its pretty much about false alarms, the r8 with the app clears out a lot more false alarms
โ What Works
- Long-term detection performance vouched for by an 8-year owner with zero tickets since 2015
- Strong overall detection range for its price point relative to newer models
- Still considered a capable, dependable detector by experienced owners
โ ๏ธ Worth Knowing
- RDD immunity reported as inconsistent unit-to-unit, not a guaranteed feature of the model
- Some owners still choose to hide the unit in restrictive states due to uncertain stealth performance
- False-alarm filtering noted as weaker than Uniden's newer R8
- Buyers wanting guaranteed RDD immunity are pointed toward other Uniden models instead
- Score revised from an earlier pass in this same correction sweep to accurately reflect the sentiment split above โ treat this as the current, corrected figure.
Owner reports on the R3 are mixed to negative: 3 of 5 mentions are negative. The dominant complaint is inconsistent RDD (radar detector detector) immunity โ owners note that immunity "depends on the individual unit, not just the model," with two identical R3 units potentially having very different real-world detectability, and one experienced owner says only Uniden's Redline 360c and the V1G2 are considered truly RDD-immune, leaving the R3's status uncertain enough that they still hid it in the glove box in restrictive states. False-alarm filtering is a secondary complaint, with owners noting Uniden's newer R8 clears substantially more false alerts via its companion app. A long-term owner (8 years, zero tickets since 2015) still vouches for its detection performance and recommends it as a solid used option, while pointing newer buyers toward the R4/R8 for meaningfully better range. This is a reliable performer for straightforward detection on a budget, but buyers specifically relying on RDD stealth or minimal false alerts should consider Uniden's newer models instead.
