Sky Demon for me
Like others I have tried one or two of the units listed but Sky Demon is and has been for over 12 months my current get me there and get me back tool of choice. It is simple to operate, very comprehensive, provides all that a vfr pilot requires, is being constantly added to and updated. I have used it both in the UK and mainland Europe and have found it an invaluable companion both when planning and when flying.
