If it’s not obvious, safety is the number one concern. If you were to head out to do some deep sea fishing (think 3-5 miles out to sea or more, depending on how hardcore you are), the dwindling horizon of the shoreline can quickly disappear. Finding your way back can be a pain, but it can also be worrisome. If you’re lost and can’t find out which way the shore is after a fun day, you’re going to panic, and that panic isn’t going to help you navigate. Your GPS is the key to safety, and to getting some accurate predictions on timing. Find out when you’re going to make landfall.\r
