Simply select the AIS box (Image 1) select NEXT and download with your Weather Routing and GRIBs etc.
Picture this scenario: cruising at 10 knots, you spot a container ship approaching at 25 knots. With conventional AIS, you have a mere 8.5 minutes to react. However, with this feature you gain 8.5 hours of advanced warning. Also a great way of missing fishing fleets well in advance.
Image 2, shows a fishing fleet mid ocean on a passage NZ to Fiji, by selecting an AIS target it provides greater detail. You have the ability to toggle AIS on and off.
This is NOT a replacement for your onboard AIS Transponder, however it is a fantastic addition.
