The AlcoSense Pro personal breathalyser will help Dad easily tell when alcohol has cleared his system the next day. It uses a slightly smaller version of exactly the same sensor used in several UK, US & European Police breathalysers. So, it’s extremely accurate.  It features a full colour screen that will give clear readings of his alcohol level and if he’s close to or over the limit the Pro will alert him not to drive.  Its Blow Coach will help him blow into it correctly to improve accuracy even further and it’s temperature sensitive, so the Pro will always give him a correct reading.  Available from Halfords, and  RRP £149.99
