Hi All, This is just to introduce a new digital vacuum guage that we have developed. All details can be viewed on our website : www.motovac.nz Unlike most other digital vacuum guages ours makes a wireless connection to your smart phone in order to display the relevant data. This is acheived by downloading a free APP to your phone. At present only Android phones are supported however we are working on a ios App for those of you who have Apple devices. We have recently uploaded a review by Bike Rider Magazine to the website which makes interesting reading. We will be very happy to answer any questions. Regards, George.
