yes, great video. Having had jammers in the past, I kind of learned the hard way. Trick is to allow the officer to get a reading but only after you have slowed down. It's a bit of an art, that you should practice.
Jammers don't automatically get you out of a ticket, but there is a much better chance of getting a regular ticket versus sitting at the side of the road watching your car getting impounded. It's a huge cash grab in British Columbia where there is only one government run insurance agency that colludes with various police agencies , especially the RCMP.
If anyone has a jammer installed on their Q60 or Q50 , I would love to see the setup and possibly some pointers on the best way to install.
