Q. If my boat is stolen and goes off-shore, will I be able to track it?

Your units' built-in GPS will allow you to track your boat up to 10 to 15 miles off-shore. In the event that your boat gets beyond that range, messages will be cached until your boat gets back within cell range. Even a stolen boat needs to come back ashore. The Siren Marine unit will start transmitting messages again when it regains a cellular connection.
