That's true, even the most expensive ones still won't pick up everything and will still make mistakes.
I heard the Valentine is very good.
Besides for the escort being great as well
The R7 is currently the best dash mount radar on the market. You can read
https://www.vortexradar.com/best-radar-detectors/ Everyone has their own needs but overall the R7 is the way to go. This site referenced is the DD for Radars with all nitty gritty testing and details.
Good means, filtering false threats, stealth and most importantly range.
The valentine was out of stock for a year +, today was literally the first day it's back In stock with a v.2.
The R7 picks up all radar, but not good at lazer.
In general if a radar Detector, detects lazer, ur toast.
You need a jammer to first shift/jam the hit and then you kill your jammer so cop can get a good reading.
If the trueway is empty and cop is shooting, this will wont help you since by the time this detector detects the laser that cop already scanned you
A detector detects radar at times from a mile+ away before the cops radar gun can get a good reading, think of it like smelling food before you get into the kitchen.
A radar gun does not help for lazer but at night cops usually dont usally lazer in low traffic, especially in areas such as the thruway where there are not many cars and can take some time for a single car to pass. Just imagine holding a gun in your hand and looking thru its scope waiting for that one car that'll pass in 20 minutes.
Radar sits and does the work on it's own.
Lazer by day can be an issue, but consider that using lazer requires a being in a stationary position which will usually be reported on waze in no time. Also, in some areas cops dont even have lazer. You can familiarize with the areas you drive In to see what cops use., or read some radar forum's.
Well not exactly, the radar detectors are there to detect a radar being shot at your car, hence the range of the radar detector I suppose is working with a much longer ranch to give you a warning, vs the actual gun the officer is using to shoot at the vehicles.
Yes and No
As described above, if your detector can pick up the signal then the cops radar can reach your car but not necessarily get a reading. Your only smelling because its reaching you.
You usally detect a bounce off something or a far week signal before the cop has a direct line of sight catch.
If you go on youtube you can watch a few demos and you'll get a good idea of how it works.
