Buddy Tracking feature when used with Raymarine multifunction display allows you to save AIS targets of interest with a special icon and zfriendlyz name. Buddy tracking makes it easy to spot the boats of friends and family out on the water, or to identify other vessels-of-interest with ease.
The AIS650 also features both hardware and software enabled Silent Mode, which enables the captain to switch off the AIS transmitter for reasons of security or privacy. When connected to Raymarine Multifunction Displays, silent mode can be enabled or disabled at-will from any display on the network. This feature is most often employed by tournament captains who do not want to reveal the position of their hot fishing spot, but is also vital to cruising power and sailing vessels who may want to temporarily disable broadcasting their position out of concern for vessel security.
