Excellent best SeaNav

Using SeaNav for years awesome

For freshwater and close land

Maximum depth 30meters

Response from developer

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
