WatchMate 850

Model: 850 Brand: Vespermarine

The AISWatchMate 850 Transponder incorporates a built-in GPS receiver and patch antenna with the award winning AISWatchMate collision avoidance display.

Using the Universal Shipborne Automatic Identification System (AIS) the AISWatchMate 850 Transponder transmits your AIS data and displays data from all AIS equipped vessels in your vicinity. Audible warning alarms are sounded if a potentially dangerous situation exists. The alarm sounds whenever a vessel is detected that will come dangerously close even though it may still be many miles away. You are alerted immediately with the closest point of approach (CPA) and the time until CPA.

Unique and customizable alarm and intelligent filter settings help to eliminate false alarms. Other vessels and alarms are displayed in a prioritized order assisting you to safely navigate in crowded shipping areas.

The AISWatchMate 850 is a fully self-contained Class B AIS transponder with GPS receiver and GPS patch antenna. It can be interfaced to other on-board electronics and will provide complete AIS output. However, it can be used totally stand-alone and it is not necessary to connect it to any other device.
