Following the sucess of the Flymaster B1 and the Flymaster F1&NAV+, Flymaster Avionics now launches a new addition to its family of high quality flight instruments, the B1 NAV. This new instrument adds to the features of the B1 all the navigation features needed for Cross Country and Competition Flights.

The B1 NAV integrates the latest GPS technology wich allows ultra fast start-up (even at weak signals). Such high precision GPS provides 4 position fixes per second (most devices only provide only 1 position per second) allowing faster response time.

The B1 NAV revolutionary new hardware provides a completely new experience, with amazing smooth graphics and almost instant information updates. Despite the differential hardware characteristics, like the high contrast and resolution screen, very sensitive variometer, large memory capacity, Radio Frequency interface for connection probes, high capacity li-on battery, etc.. B1 NAV boasts many powerful and unique software features, with an intuitive user friendly interface.

Flymaster B1 NAV is the best value for money integrated GPS/Vario designed to make your navigation easier.

* Also includes membership of US based Flymaster discussion group for sharing tips and getting the best support.

Competition route optimisation leads to pilot into cylinders at the optimum point to reduce distance to the following waypoint.




Last thermal marker shown by the black spot. Last thermal can be found by moving the black spot into the center of the compass rose.


Reviews of the B1 Nav as appeared in the US Hanggliding and Paragliding Magazine can be found at this link.

There is a great report at a PWC from 2010 where one pilot is talking about the B1 Nav. Here is the link. Go to 3 mins and 50 seconds for Mark's review.
