Why did you choose this?
Sonic Electronix Store
Since mine was stolen. I chose this one because it detected more bands and had the pop feature.

Does this unit have "selectable band defeat", which is the ability to turn of any radar band and Laser (if it's not used in your area)? Does it have auto dim and auto mute modes?
