  • NMEA 2000 connectivity

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.

Small small size but nice to carry around in purse or beach bag.
Style: Face Stick, Size: 0.45 Ounce (Pack of 1)
This sunblock works really well. I like that it is only mineral based and it glides on easily . Due to its compact size I can carry this in my makeup bag. I placed sunblock every 2 hours on my face while I was in the swimming pool and I never got a sunburn. Pricey but easy to apply and compact size .

Great for the face

Works well, nice ingredients and easy on our babies skin. They do leave a white tint though that can take awhile to fully rub in

Style: Face Stick, Size: 0.45 Ounce (Pack of 1)
Great product, just wish I had read the description better because this stick is TINY. On the flip side, its easy to carry around and doesn't gulf my baby's face.

Bought this for my daughter and she quickly got used to applying it herself. The stick format makes it super practical and less messy. Great option for everyday use.
