Which AIS Transponder Is Best?

Looking for a cheap but functional AIS Transponder. A unit that shows the vessels around me and also transmits my vessel to others. I have two chart plotters, so I don't need the unit to have it's own display.

If you're interface will be through a nmea 2000 conection, I have and like the garmin unit, under $700. With any of the units you are considering, make sure they are compatible with your plotter.

Is the Garmin 600 the one that you have installed?

Yes, that's the unit I have. Bought mine over a year ago. They're now just under $800 or my memory is a little faulty.

We're fully Raymarine, and will be getting the AIS650 soon. Currently, we have AIS receive thru a SH 2150GX interfaced via NMEA 0183.

One of the features I like about my Garmin that may or may not be standard with all units is the ability to have it on (transmitting) with the plotters off. I wired the power to the same breaker as the nmea 2000 network. Basically this allows me to have a very simple display to monitor depth, wind, anchor drag, and broadcast AIS while at anchor with almost no power consumption. The AIS requires a significant amperage input, but the higher consumption is only for a fraction of a second when it transmits. I leave mine on whenever anchoring out for the night.

This is the one I installed. Cost low $500s. Seems to work fine with my Garmin plotter. Nmea 2000 backbone.

Having the AIS on while anchored at night is a great idea. One I did not consider.

Looks like a nice unit at a good price. I also will be wiring to a Garmin 740S that has NEMA 2000.

I also have the SiTex Metadata B. Have been running it for 4 years. Interestingly, the way it displays on the chartplotter has alot to do with the chart plotter's own processing software. For example for two years we ere running it using Open CPN software and it showed all the intersects such as time to closest approach and the distance at closest approach and such information on the screen. Recently we have been using Coastal Explorer now the main screen shows the contact's course and speed, but a separate tab has the CPA and the TCPA. We like the CE approach better as there is less clutter. CE software is better at filtering out targets with low risk.

Cardude and Tadhana: do you have an external gps for this or do you use the internal gps?

Did you use a dedicated VHF antenna or did you use one of the VHF splitter modules?

Comar CSB200, bought it new on eBay for $230.00, did a saved search until I found a bargain.

We started with a Standard Horizon combo VHF/AIS receiver networked with our MFD. We then added an independent Em Trek Ais transceiver using only the transmit capability. At night we can shut down most everything except the AIS transmit as does O C Diver. This setup works well for us.

I used the internal GPS. I think I had to buy a little GPS antenna for the Sitex though. It didn't come with one.

I used a splitter, but just because I didn't have enough room to run another cable. Or I was too lazy. Don't remember which. If possible I would use a dedicated VHF antenna.

I am definitely lazy. If I could get it to work without having to run another cable, that would be fantastic.

If you're lazy like me, this is the splitter I used. It has a booster so I don't think I lost much signal strength with my VHF. Actually according to the specs I may have gained some! Win/win for the lazy people!! Not super cheap, but neither is my time. Well actually my time is kind of cheap since I don't do much, but I'd rather be chillin with an umbrella drink than cussing running cables, so that's how I justified it.
