Marine Navigation & Instruments, Supplies and Equipment With a wide variety of Marine Navigation equipment and Instruments, we can help you find your location on the waterways, avoid hazards, and be respectful of other boaters. The accessories you have on your boat are important, but very few of them are as valuable as the AIS systems, autopilots, black box modules, and other options you can choose from when you want to make sure you can find your way there and back again while staying away from areas that could mean running aground or experiencing other dangers. We offer many types of navigation equipment, including cameras - network video, ice flashers, and marine monitors.   Depending on where you are going to be boating and what you plan to do with your time on the water, you can also find a fishfinder/sounder - color or a fishfinder/sounder - mono that will be right for you, along with GPS - chartplotters, GPS - fishfinder combos, or a GPS - track plotter. Network accessories and network capable displays are available, and we have a selection of night vision, software, transducers and transducer accessories, and weather fax equipment. If you need radar - stand alone options or radar domes / arrays, look no further than right here, where the selection is good and so are the prices.

SPL1500 Antenna Splitter VHF/AIS An AIS receiver or transponder requires a VHF antenna, but Digital Yacht’s SPL1500 AIS-VHF antenna splitter allows an existing antenna to be used for both the AIS and VHF (DSC). Unlike most simple splitters, it can also be used with a class B transponder system and it incorporates special circuitry to ensure safe operation of the two transmitting devices. The unit has three simple connections - one input for the main VHF antenna and then outputs for the AIS receiver/transponder and another for the DSC VHF. It utilizes Digital Yacht’s ZeroLoss™ technology, to ensure the very best possible reception and transmission from all devices. Most importantly it is also fail safe, so should the unit ever stop working or lose power, it will not affect the main VHF operation. Until now, Digital Yacht, have recommended a dedicated antenna for a receiver or transponder.  However, with the new this new ZeroLoss™ technology, we can now offer a solution that greatly simplifies installation whilst maintaining performance. The unit is waterproof and matches the aesthetics of the current AIT1500, so can easily be integrated into any vessel. It is suitable for operation on 12V or 24V systems and features three status LEDs that show the unit is powered correctly and when the AIS or VHF transmits. Features:  Enables an existing VHF antenna to be used for both the standard VHF and AIS system ZeroLoss™ technology for exceptional performance Works with all Class B transponders and receivers Supplied with power cable, PL259-PL259 cable assembly and BNC-BNC cable assembly for easy installation (all cables 0.75m long) 12V or 24V 0peration and low power consumption Fail safe operation Same size and design as the AIT1500 Makes installation of an AIS receiver or transponder very quick and simple Saves on additional antenna clutter

AIT2500 Class B+ 5W SOTDMA AIS with GPS Digital Yacht have a range of Class B+ AIS transponders. Class B+, a standard, utilizes 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’s 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 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. Specifications: Class B+ 5W transponder with GPS/GLONASS positioning Multiple NMEA 0183 in/out and multiplex capability NMEA 2000 connectivity USB connectivity for PC/MAC Remote TX silence switch option Supplied with GPS antenna Options include VHF-AIS antenna splitter, wireless interface (WLN10SM) and AIS SART Alarm (AIS Lifeguard) Note On SOTDMA Technology Class B+ is a 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.  With regular Class B protocol, the transmission rate is fixed at every 30 seconds when the vessel is moving. It is ideal for ocean sailors requiring the best possible performance and future proof satellite tracking applications, fast power boats and smaller non-mandated commercial vessels.
