Overview

The T300B-S is a compact and rugged SOTDMA AIS Transponder with built-in Antenna Splitter designed for the demands of the small commercial boat fishing boat and leisure markets. It meets the Class ‘B’ (SOTDMA) standard allowing vessels that are not required to fit Class ‘A’ units to voluntarily fit an AIS Transponder.

When connected to an external VHF antenna and a GPS antenna (not supplied) the T300B-S will transmit its own vessel position and data and receive information from other AIS vessels shore stations and navigational aids within VHF range.

The built-in Antenna Splitter allows the unit to share a single VHF antenna with a VHF radiotelephone eliminating the need for a second VHF antenna on the vessel and reducing installation time and cost. Additionally the unit has an FM radio output for monitoring public service FM radio broadcasts.

The unit is initially programmed by the user with the supplied software over a USB interface. The T300B-S is compatible with a range of computer based navigation programs and chart plotters that accept AIS data sentences over a NMEA 0183 or NMEA 2000 connection.

Applications

  • Commercial boat fishing boat and leisure markets
  • Meets the Class ‘B’ SOTDMA international standard

Good toy for dogs
This is a great toy! I do wish the handle was a little longer because I do not have a lot of upper body strength due to health issues. I can still throw with this further than I can without the launcher so my dogs really love it and get excited any time I get this out!

Too small
Much smaller than it appeared to me in the picture. I did not read the length as I should. I would not have bought it if I saw it before purchasing. My 18 month old grandson now has a new toy.

Very convenient, soft, comfortable and does its job.
Size: 3 Pairs - Gray, Green, Pink
As a first responder being on your feet consistently in heavy boots really takes a toll. I buy new soles for my boots and noticed the inconsistency balance from heel to toe which caused cracked and dry heels. I was desperate to find an immediate solution and saw these. Received all the socks individually wrapped, I am a size 5 1/2 to 6 in women’s shoes and they fit so snuggly. They are convenient, they fit under my work socks due to them only covering a portion of the foot and heel, the inside where the heel is a soft rubber material that helps keeps it in place, as well as if you use ointment or oils. The socks are soft and very comfortable that at the end of the day you forget you are wearing them. They are also washable both in the washer or hand washed and it doesn’t affect the rubber material. Highly recommend especially after a foot spa day.
