Just thought this was some interesting information from the past.
It compares the Passport 7500, Passport SR1, Valentine One, Bel 915, Bel 980, PNI RX5000, Uniden 767, Whistler 1270, Whistler 1670, and Cobra 9850.
I think it is interesting that the Bel 980 beats the V1 in X and K band.
One of the images shows how the Valentine One compared to the best at the time and also how it compared to a 1986 Passport, 1991 Solo, and 1991 Escort DSP in X and K band detection.
Don't forget to check out the picture of what the Original Passport could have been had Mike Valentine stayed around.
Take a look at the X50 with arrows and wonder what could be if Valentine One, Escort, and Bel all merge to crush any remaining detector makers.
