Been playing with the idea of AIS for some time, as we operate in what can be "remote" areas, with no other vessels around (yes even on the South Coast), I would like to have the benefit of increased visibilty.
A full system to go on our existing plotter is very pricey and this may be an answer at the right price

I am not sure of the benefits of this unit over a conventional class B AIS. It will have the same transmitting parameters as a class B and therefore the same limitations (limited Tx range, relatively infrequent position updates (particularly when there is a lot of AIS traffic), can be filtered out by receiving stations)

Compared to a standard class B I would say:

Pros:

1. Cost (possibly?)
2. Ease of use (no real installation required)

Cons

1. Lower power than a class B (ie reduced range)
2. Has to be kept charged rather than just being powered from the boat.
3. Cannot receive AIS data (ie can't display other vessels on your plotter)

It shouldn't be that pricey - a class B transceiver should be sub 400, with no worries about keeping batteries charged. A class A transceiver is going to be a lot more expensive (with good reason), but it is not really fair to compare this identifier with a class A when a class A offers a lot more (to those who need it).

Are you sure it's a TX led & not an RX then?

This is the unit on trial and I have seen AIS pings for the boat on AIS webpages.

SRT marine technology working on these for future options
