Ratings and reviews

Game Changer! Fast, Initiative and Incredibly Useful. The charts are accurate and were easy to load and navigate with. The integration with a Sounder is beyond cool, as I can now have a handheld remote when I'm on the back deck on the kicker and I can't see the main display. fully compatible with my FCV800 via Wi-Fi connection. Not a single hiccup. I highly recommend this ap.

I have been using your products since the mid 90’s and always look forward to the new releases. This one tops them all by a long shot. The one thing I was hoping to see was the Route Wizard”. Is it there and I just can’t find it?

Have been using Nobeltec navigation for decades. Now it's the TZ app. Full service information. Bit of a learning curve but well worth it!💪
