The CLA1000 from Digital Deep Sea is a fully approved, Class A transponder that meets all of the IMO requirements. Built to the most demanding of standards, the CLA1000 is MED Wheel Marked and comes with a global 2 year warranty. Normally fitted to larger vessels that are mandated to fit a Class A Transponder due to their size or number of passengers, many smaller non-mandated vessels can also benefit from fitting a Class A transponder. With 12W transmit power, compared to 2W for Class B, many off shore sail boats would benefit from being visible at greater ranges, whilst the faster (up to every 2 seconds) update rate of the Class A transmissions, compared to every 30 seconds with Class B, will definitely benefit the larger power boats that can go a long distance in 30 seconds. - Two other important benefits of Class A - Transponders are that they take priority over - Class B transponders in areas of high AIS traffic (transmission slot allocation is guaranteed for Class A transponders) and they are always displayed on the Class A transponders and ECDIS systems on board large commercial vessels. - Fully approved and MED Wheel Marked Class A Transponder - Ultra Compact Design - Easy soft key and rotary encoder operation - Built-in GPS with easy to fit 1" x 14tpi mount GPS antenna - Pilot Plug for easy PC connection - Remote break out box for on-board interfacing - Supplied with configuration software and - SmarterTrack Lite AIS software
