TPX System Receives Four Stars From Radar Roy

Originally posted 3/13/2008

I traveled to Arizona with our tech guru, Adam, earlier this week to meet with Radar Roy, one of the most reputable evaluators of radar detectors in the market today. Radar Roy is a retired cop and a certified radar instructor. He has over 20 years of experience with the radar detector industry and runs a blog dedicated to the evaluation of radar detectors at

Before our arrival, we had sent Roy prototype and production units for him to play with. He provided us with feedbacks and suggestions on what he liked and didn't like.
Roy liked our design and simple set up, and was particularly impressed with TPX's overall performance. In the end, Roy gave us Four Stars with his rating system.

While we were out there, Roy took us on a ride in his truck to show us the route where he conduct his tests and ran the
TPX along side with his remote Escort SR7 unit that he uses for baseline comparison. His remote Escort SR7 unit has a remote radar antennae mounted to the front grill of his truck, thus he's able to run the two detectors at the same time without any cross-interference.

TPX picked up all the radar signals at almost the exact same time as his SR7. There were a few instances where the TPX picked up signals before the SR7 and vice versa, but overall the detection ability was almost identical, including quite a few times where we were coming around blind curves on the road. The SR7 had a few false alerts, and so did we, and in two particular locations we picked up false alerts and the SR7 didn't: one around a stretch of the road filled with gas stations and auto shops where we picked up a false X, and at the local fire station where we picked up a false Ka. There was one location that the SR7 picked up a false K and we didn't, at an intersection with a gas station occupied at one of the corners.

In Roy's blog, he also mentioned about the reduced sensitivity in City mode. This is by design because there are more interfering signals in the city and chances are, you are not going that fast, so we designed the City mode with about half of the sensitivity as compared to Highway mode.

Overall, we were impressed with Roy's impartiality and brutal honesty, and we are definitely happy that he gave the TPX System a Four Star rating.
