The Pro is the next level up and is one of the most advanced breathalysers on the market in this price range. It features a 121mm2 Fuel Cell Sensor, still slightly smaller than a Police sensor, a Time until Sober and Retest alarm, a selectable database of all drink drive limits worldwide as well as the Blow Coach which make for user friendly testing. Results are displayed on the screen in clear, colour coded indicators so there is no difficulty deciphering percentages or confusing data. RRP £149.99
