Bearing Pilot vs Qastor

Bearing Pilot is a new tool for both beginners and profesional sailors. 
Its extreme simplicity let us take quick apparent bearings, showing us in the screen the bearing taken, the target course and also the correction required at the wheel (in dregrees). Additionally, it provides speed and real-time position. Using a piece of wool or tasting winds, it also help us to get the wind direction easily. 
Several tools in just one easy App.
A great tool for racers, buoy tenders, professionals and recreational sailors. Marinus Apps www.marinusapps.com
