Hi, there is a Max Depth option in SeaNav Advanced Settings which defaults to 20m. Change it to All to show all depths and you will then see all the contours and depths greater than 30m. Looking at the Tasman Sea I can see contours out at 4000m and greater. I hope this helps? Fair winds The PocketMariner crew

Hi, SeaNav does not need internet to work. It can download and store all the necessary charts and tides for offline use. The only features that require internet are the internet AIS add-on and live weather. Could you please email us at help@pocketmariner.com so we can understand what was not working for you and help? Best regards The PocketMariner Team

Hi Tyler, I am very sorry to hear that. It doesn’t sound right and we haven’t seen that in testing or had other similar feedback. There must be something unique going on. Could you please email us at help@pocketmariner.com so we can get you un-stuck as soon as possible. Best regards The PocketMariner crew
