Hey LoCoZ2-
You might considerhaving your detector face a little more horizontal. It will help, since most cops aren't facing underneath your hood. Your rear detection will be effected also.
Just remember to always have at least one car in front of you to set-off the radar detector. Cops these days will pulse cars instead of leaving it on like in the good old days.
BTW I have had a Whistler for 3 years now and and it has saved me from numerous tickets. It only cost me $79 and has pulse detection, rear detection and laser detection and is digital. Got it at HSN
