Start an Anchor Alert Session
To start an Anchor Alert session in the Anchor Alert App:
Connect your device to DataHub Wi-Fi and open the Anchor Alert App.
Tap the globe icon at the bottom left of the screen to open the Anchor Map page.
Top left of the screen, next to the hamburger menu (three horizontal lines), check the DataHub Wi-Fi symbol is green, indicating the app is connected to the DataHub.
Note: If the DataHub Wi-Fi symbol is red, drop the app into the background, check that your device is connected to DataHub Wi-Fi and reopen the app. If you have changed the default password or IP settings for the DataHub, please read here how to edit the Anchor Alert App DataHub Connection settings.
On the Anchor App Map page, tap Start.
Set your Chain Rode.
Rotate your device to the correct heading towards the anchor set point. The phone heading is displayed in degrees at the top centre of the Anchor Map page.
Tap Set Anchor Position and then tap Set Alert Now.
When an Alert session is started, your boat's current GPS position will be displayed on the Anchor Map screen. On the Dashboard screen, your boat's live anchor alert session data and the boat's N2K data are updated on DataHub Wi-Fi.
If you leave the boat and the DataHub is connected to high-speed Wi-Fi, the DataHub will update the boat's position to the PredictWind servers each minute. To retrieve the latest data from your boat, tap Refresh Data. Any alerts triggered will be delivered immediately.
