Set Your Anchor Alarm to 70m

In the Gulf of Thailand, unexpected NE squalls can develop overnight and ferry wash can drag an unmonitored anchor. Safety Anchor Alarm monitors your GPS position continuously — so you can enjoy the Full Moon Party, dive sites, and tropical evenings knowing your boat is protected.
