The remote detectors produced by whistler now are based on a old platform. DE 3500 and Pro 3450 are the equivalent of Pro 73 from what I know. They are a bit obsolete now. The filtering and range are not good enough for 2010, 3450 has some reliability problems... They are not a real option for someone who wants a remote detector.
I would like a remote detector based on the new platform, Pro 78, maybe even a waterproof remote detector for motorcycle. Is there a chance to see such a product soon?
One thing I don't like about the new whistlers is the old style volume control.
Another thing Whistlers don't have is the calibration circuit. Belscorts tell you when they are not working properly, with wistlers you can find this when you get the ticket.
