En changeant de téléphone j’ai perdu la cartographie que j’avais acquise avant l’annualisation de de votre application. C’est décevant Je reviens aux cartes papiers La ferme marine a l’entrée de Concarneau ne figure pas sur la carte…

Ich nutze schon lange von Garmin die Boating App. Mit weiteren Apps zu Wetter und Liegelätzen kann man damit schon was anfangen. Über einen Fachartikel bin ich auf die App TZ iBoat gestoßen und konnte diese eine Woche im Urlaub testen. Welch ein Unterschied zu Garmin, Fragen zu der Nutzung der App wurden vom Support umgehend beantwortet, die FAQ ist in Englisch, wer kein Englisch kann lässt sich den Text halt übersetzen. Themen wie digitale Ankerwache, Wettervorhersagen aller Art (kostenpflichtig), Routenwahl, Routenverfolgung oder Schutz des Ankerplatzes bei Wind und Schwell sind kinderleicht zu nutzen und haben auch erfahrene Mitsegler verblüfft.

Nachdem ich eine Jahres Abo abgeschlossen habe funktionieren die Funktionen nicht mehr, Display wird sofort dunkel und kein gps wird immer verloren, nach mehreren Versuchen jemanden zu erreichen würde leider erfolglos. Abo gekündigt. Sehr enttäuscht

superhilfreich beim navigieren in schwierigen Gewässern, für mich in der dänischen Südsee , die ich somit ohne Grundberührung erkunden konnte

Loading gpx files for search and rescue into TZ2 is a breeze. Makes for accurate coverage without the need to enter points whilst underway.

For some reason the relief shading just stopped randomly in the middle of the river just before a bridge

Next level navigation aid. I back it up with Garmin 7600. TZi easily is better! Buy it for 15$..

Tolle App zu Navigation. Gerade das Feature Raster-und Vektorkarten zu benutzen gefällt mir sehr gut. Auch die intuitive Bedienung ist gut gelungen.
