  • Multiple NMEA 0183 in/out and multiplex capability
  • NMEA 2000 connectivity
  • USB connectivity for PC/MAC
  • Remote TX silence switch option

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’m really happy with these lights! They were easy to set up, work perfectly, and give off a beautiful glow. The brightness is just right for creating a cozy and relaxing atmosphere without being too harsh. The quality feels great for the price, and they instantly made my space look more modern and inviting. I also appreciated how well they were packaged and how quickly they arrived. Definitely worth the purchase, and I would absolutely buy them again. Highly recommend to anyone looking for stylish and reliable lights!

Termitor H11 are so worth it
Size: H11+9005
LED Lights are as described. They fit perfect in the low beams and high beam spots. LEDs are super bright and work great at night! Soo much better than the old fluorescent bulbs that came with my rig.

Bright light
Size: 9004/HB1, Size: 9004/HB1
Keeping track of longevity. Had these bulbs for a month and will try and update if they fail. Unfortunately a while ago I hit a cow, seemed to just pop up out of nowhere, the truck was rebuilt and I wanted more/better road lighting. I am using these in a Mack truck for work so they are getting used. I run at least 10 hours a day, 5+ days a week and have at least 11k miles on them since installed. Install is just like a standard bulb no special steps needed. Produce a lot of light and good patterns on high and low beam. So far I really have only had one issue with the bulbs and that is the daylight running light/DRL operation, they don't work I believe the Mack drops the voltage to slightly dim the lights when running in DRL operation and this causes the bulbs to just intermittently flash so I just run with them on all the time. This I don't believe is the bulbs fault and is more an analog vs digital issue. Therefore I'm testing the longevity of the bulbs if my truck is running they are on. Will see how they do as the days get hotter as they are in a small sealed space.

Wow bright!
Size: H11+9005, Size: H11+9005
I have used Fahren LED headlights in two of my other vehicles so I had a baseline of what to expect, but these upgraded ones are even brighter than the ones in my other two cars. I love this brand because they are plug and Play so I have not experienced any compatibility issues. These feel high quality as I have expected due to past experience with this brand. I much prefer the bright white color of LED versus the yellowish Amber of halogens. I have been using this brand for several years now so I expect a good lifespan from this as I have experienced from other bulbs from this manufacturer. As far as value goes, the increase in visibility installing these is worth every penny and then some.

Good light, but blinding
Size: H7
The light itself is good and bright and fits well, but I don't know if I installed it wrong, but the driver's side is very blinding, and I feel bad for other drivers and can't do anything about it.
