Not very useful for marking and guiding you to your favorite spots

As an avid fishermen and diver I was hoping this would provide a way of inputing the numbers for my favorite spots. The problem is once you input your numbers and save, them the app takes it upon itself to change them. It appears it either rounds them up or down depending on its mood. If you looking for an app that will accurately store and guide to your favorite spots this is not the app for you. BTW I reported this months ago without any resolution. Was hoping the latest version would correct it.
