Didn't see anyone else post this so I thought I should as I thought this was important for the people who use the STi in illegal areas. Apparently, there's a new spectre called the Spectre IV+ , alpinestars_2002795 mentions it is detectable at roughly 500ft
After reading apline's post, I decided to go on one of the spectre sites and it used to say the spectre detects all but two but now it's changed and says
I guess this also means the 9500CI and the STi-R are detectable as well since they use the STi's antenna. Just trying to keep the people who depend on the STi informed.The Spectre IV and IV+ spot radar detectors by detecting electromagnetic "leakage" from a component common to every radar detector, the local oscillator. Some manufacturers try to screen out the leakage with shielding; others try to adjust the leakage to a frequency that the Spectre isn't sensitive to. So far all radar detector manufacturers have failed and their products are easily detected by the Spectre.
