The compact Class B AISLink CB1 AIS transceiver module — one of the first automatic identification system products from ACR Electronics — networks easily with a wide range of navigational systems and multifunction displays, thanks to both NMEA 2000 and NMEA 0183 interfaces. The size of the AISLink CB1 allows for installation just about anywhere, such as behind the helm of small center-consoles, to share navigational data with nearby vessels — even those obstructed by radar — for greater safety. $950 (excluding antennas); acrartex.com
