I have been looking and reading a lot around this site. I drive a lot for my work and can easily put 300 miles or so in less than 3 weeks on a vehicle. I was running an old Whistler1750 until the speaker quit again and without the audio alert it is pretty much useless. I know it was old, but it served it's purpose in the state I live in. I just ordered a Pro78SE and it will get a new home in my private vehicle replacing my older Pro73SE. The Pro73SE will be riding in my company vehicle standing guard. My main use is just for alerting me about a presence of radar. I mainly use visual cues about oncomming traffic since we don't have much traffic in the state I live in. You can really see for miles up here.
So my big question? How does the Pro78SE compare to the Pro73SE?
