The 1st Mate app puts you in control of your vessel by interacting seamlessly with the 1st Mate system installed. You can easily control Theft Deterrent features, see Man Over Board alerts and give time limited access to your loved ones, or even the service guy. 1st Mate from Mercury and Quicksilver is the world's first engine-integrated man overboard and proximity-based theft deterrent system. Utilizing a highly styled wearable for up to 8 people, 1st Mate turns the engine off or sounds an alarm during a man overboard event (MOB), and optionally sends notifications to emergency contacts. If the proximity of the fob is not in range, the system disables or puts engine in guardian mode. All these functions are covering boaters most important needs, namely safety and security.
