Currently the RCMP uses a model called the Dräger. It has a feature in it, just as an app, whereas the roadside screening device asks you to blow into a mouthpiece. You just click to the right and it has a feature that will actually suck the air in, so it's built into it. They're highly effective. In the eighties, they were really large wands. Since then, the technology has come quite far.
