Digital Yacht have introduced a new range of Class B+ AIS transponders. Class B+ a new standard utilises SOTDMA format transmissions which offer a 5W power output (2.5x more powerful than a regular Class B) a guaranteed time slot for transmission in busy traffic areas and faster update rates depending upon the speed of the vessel. It is therefore ideal for ocean sailors requiring the best possible performance and future proof satellite tracking applications fast power boats and smaller non-mandated commercial vessels. It still inter-operates with existing Class B and Class A systems.
The AIT2500 is a full function SOTDMA AIS transponder with NMEA 0183 NMEA 2000 and USB data outputs. It is also supplied with a GPS antenna and requires connection to a VHF antenna or suitable VHF-AIS antenna splitter.
The AIT2500 has the option of an AIS SART alarm which is great for use with personal AIS MOB devices.
NOTE ON SOTDMA TECHNOLOGY
Class B+ is a new generation of AIS functionality based on SOTDMA (self organised TMDA) messaging rather than the simpler CSTDMA (carrier sense TDMA). It guarantees your AIS transmission will get a time slot even in areas of very high traffic density. It also specifies a 5W transmission power (compared with 2W for Class B) and a transmission rate that increases as the vessel moves faster. The transmission rate is fixed at every 30 seconds when the vessel is moving with regular Class B protocol. It is therefore ideal for ocean sailors requiring the best possible performance and future proof satellite tracking applications fast power boats and smaller non-mandated commercial vessels.

I was looking for a mask and snorkel to take on holiday and after taking Russell’s advice I found exactly what I was looking for. My order from Waterworld sports was received on the following Monday after I had placed the order on the Friday before. Very pleased with my mask and snorkel and the overall service.
Thanks Russell.
Bought a wetsuit from these guys. Russell did the best possible job of ensuring I received it on time for my Egypt trip. Great work and reassuring communications. Also the price was exceptional. Always a pleasure to deal with. Steve - scuba instructor

Excellent company for our first Watersport purchases (snorkelling). Great prices and communication via email and phone to help us select the right gear. Also nice to know they have a shop in Greater London for collection, or you can use the super fast delivery which arrives on time (when it should).
Very personal service to supply a wetsuit, starting from a Google search for a specific brand and size, followed by personal engagement by Russel to check in size, agree price and shipment. Thank you
Bought fins and dive hood, extremely helpful advice from Russell about sizes, fit snd suitability over the phone. Swift delivery to the store as the fins needed ordering and trying on. Great, friendly service in the shop and would definitely recommend. Thank you.
Managed to source a part I couldn’t locate elsewhere, good price and quick delivery. Couldn’t ask for more.
I ordered a snorkelling mask with inserts for my eye sight. They mask with the inserts fitted arrived in a couple of days, well packaged. The inserts are amazing and allow me to see underwater! I am currently in the Maldives and it was worth every penny!
