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

Vesper Marine has designed the AISWatchMate Transponder to help avoid collisions at sea. Using the Universal Shipborne Automatic Identification System (AIS) the AISWatchMate Transpondertransmits 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 ship is detected that will come dangerously close even though the ship may still be many miles away. You are alerted immediately with the closest point of approach (CPA) and the time until CPA.

Unique and customisable alarm and intelligent filter settings help to eliminate false alarms. Ships and alarms are displayed in a prioritised order assisting you to safely navigate in crowded shipping areas.

The AISWatchMate Transponder has a built-in Class B AIS transponder with GPS receiver and GPS patch antenna. It can be interfaced to other on-board electronics and will provide full AIS output. However, it can be used completely stand-alone and it is not necessary to connect it to any other device.
