Does anybody have BOTH the valentine one and the passport escort 8500?

If you do - can you put BOTH of them in one car and drive for a little while and see if they interfere with each other please?

(Just an idea of mine I want to test out before I buy the passport - long story)

Thanks

 

I've done it in the past to decide which one I wanted and I didn't notice any interference, but how would I know? They both seemed to work well and I never could conclude which one had better range, so I went with the V1 for the arrows. Check out the V1 site and there's a long explaintion as to why you can't accurately test 2 detectors in the same car.

 

Thanks ahkim!
