My first post here on RDJF. I live in Canada and RD are not allowed. I still would like to oun one but am warried about being detected with one turned on. I have heard that there is a feature on some models called "Spectre Stealth", that makes the unit undetectable is this true and is it effective? The Cobra XRS 9950 has this feature. But I like the Beltronics VECTOR 995. Any suggestions?
