Working it out right now.Not as much as you do! I've seen some posts you've made where you drove through like 3 states with the DualPro 360. As of right now I mostly drive to class (40 minutes to and back), errands, and once every two weeks to buy food for my tarantulas. But I drive a fast car.
The videos you linked are the same ones I saw and made me decide to buy the DualPro 360 (and return the Road Scout). The DualPro 360 really is a detector people should give a try.
You should get the DualPro 360, stop thinking about it.
Time and testing will tell the tale!
