Have there been any test done by anyone comparing the Bel STIR Plus Usa & Bel STIR Plus EU ? Does anyone know which detector has better detection if any ? I have been to many radar detectors web sites and I don't remember if I ever seen anyone compare the two detectors. I use to own a Bel STIR and the detection was perfect specially in a combination with the V1. I would love a answer to my question if anyone can tell me or have any details about this please be my guess to explain or to copy and pace a URL with the information.
