Para calcular a classificação geral de estrelas e a análise percentual por estrela, não usamos uma média simples. Em vez disso, nosso sistema considera coisas como se uma avaliação é recente e se o avaliador comprou o item na Amazon. Ele também analisa avaliações para verificar a confiabilidade.
I purchased this marine gps unit on July 4th 2012 and used it on a trip from Canary Wharf to Harwich and back on an old coal fired steam tug later on that month. I cannot praise it's performance enough being totally accurate at all times and even more useful with the micro SD card containing the Dover to Amsterdam and England Southeast marine chart which I purchased direct from Garmin. It took some time to work through the full instruction manual(downloaded from Garmin)and I had to phone Garmin a couple of times for help which was politely and patiently given. This unit gave great piece of mind during our trip and I would thoroughly recommend it.
I knew what I was getting reasonable cost and reliable as I have an older unit that I use for locating survey reference control points with a little change from latitude and Long to northing and easting coordinates. I consider it a valuable piece of equipment.
Das Display ist gut abzulesen, es spiegelt nicht. Auch die Menüführung ist benutzerfreundlich.Auch kann man Routen speichern und muss sie nicht immer wieder neu eingeben und man kann es nicht nur zur See sondern auch an Land benützen, das war ffür uns für den Kauf entscheidend.
