Man Overboard by PredictWind

Features
Read full description

The Man Overboard (MOB) App requires a PredictWind Pro subscription per boat and DataHub Pro hardware. When someone goes overboard, hesitation costs lives. The Man Overboard App notifies the entire crew the instant a fall is detected - automatically, precisely, and without pressing a single button. How it works A fall overboard breaks the WiFi connection between the crew member's iPhone, Apple or Garmin Watch, and the boat's DataHub Pro. The app detects this instantly, marks the exact overboard location on your chartplotter, and fires an alert to the entire crew simultaneously. Key features AUTOMATIC MOB DETECTION Detection happens the moment the wifi connection is lost. INSTANT CHARTPLOTTER MARKING The exact GPS coordinates are automatically set as a waypoint on your chartplotter the moment MOB is detected. CREW-WIDE ALERTS Every Apple or Garmin Watch and iPhone connected to your DataHub Pro receives the alert at the same time, so the entire crew can respond quickly. Works on Apple or Garmin Watch and iPhone. Get set up before you need it. Man Overboard Watch App runs silently in the background; no attention required, no action needed. Just protection that's there when it matters most. ​https://www.predictwind.com/about-us/terms-and-conditions ​https://www.predictwind.com/about-us/privacy-policy
