Like the title says, how far should you approximately pick up X from? So far, I have picked up X from 1 mile, .5 mile, .7, and .7. These distances are either from the cop directly gunning towards me or if he is sitting in the shoulder. Even though my V1 did pick up the signals, I feel like maybe the range should be further. 3 out of these 4 times the stretch of highway was straight but one time it was a bit over the hill. Also, I have my V1 mounted high up like an inch left of my rearview mirror.
On a side note, sorry for a noob question, but how long does it take for a cop to read your speed using radar?
