SPECTRE RDDs (radar detector detectors) can be found in Canada, Virginia, and at some truck weigh stations. With K band there were a lot of different settings combinations to test with each detector so I dropped things down to just 2 passes per detector / settings combos. The only difference between one and two is how the signal strength of the primary threat is displayed. The MRCD detection is much better than it used to be, helping with photo trucks and red light cameras, which usually give off a low, flickering signal, although there is still a decent bit of MRCD and MCRT false alerts. The claim to fame for the Radenso XP is its ability to offer an extremely quiet ride, even in urban settings, which are ripe with false threats.

Uniden, as a company, is known for making long-range radar detectors, and the Uniden R3 is no exception.If I drove more than a handful of miles monthly, I'd definitely invest the money to have this, the absolute best Detector on earth. The XP is the perfect daily driver for city dwellers, with a shorter range and many features that help mitigate false alerts and keep your drive quiet. The Auto feature actually improves the range when traveling above the manually set speed as it kicks the device into highway mode.

Whether on a long straight highway, in a busy city, or driving through winding mountain roads, these models consistently picked up radar frequencies before their competitors.

It is accurate with excellent range — we could detect a cop over 5 miles away through winding mountainous roads. We did, however, have trouble hearing the alerts as the sounds were lost when the cab was particularly noisy.
