Transducer Question

[chrisferro]

Does anybody know the difference between the DST800, DST100, DST110 and the B744V transducers?

They all provide depth, speed and temp, and the B744V has a fairing that I guess it needs to be installed with, but other than that I can't tell the difference between them. I want to install a triducer, and there seems to be only 1 company on Earth that makes them: Maretron (or Airmar, I can't tell if they are the same company or not). All of this is very confusing and the more I surf the web and research the more confused I get.

Can anybody clear this up?

It's Airmar that produces them. You can buy the same ones from Furuno, Raymarine etc.

You must check & compare more specs:

- interface type, ie. NMEA0183, 2000 etc.
- power output

If you have N2K network, you probably want the 110 which is the replacement of the 100. The 800 doesn't exist I think but would have been ultrasonic speed instead of paddle wheel ???? The 744 is just a transducer, not complete sensor unit.

But all this is without checking it so it can be completely wrong... but should point ut how to select what you need.

Hi Nick,

What do you mean when you say that the B744V is just a transducer and not a complete sensor unit?

And what do you mean that the DST800 doesn't exist? And pictures of the DST800 clearly show that it has a paddle wheel. And I've looked at all of them, and the 100, 110 and 800 are all NMEA 2000. I can't tell if the B744V is or not.

The tech support guys at Airmar ate great , give them a call. I have a b744v that was already in the boat when I got it. It is not nmea 2000 compatible. Needs to be plugged in yo the correct sounder unit. And there are different models of each unit , that are sounder specific . Mine was ordered for a lawrance unit , and I bought all garmin stuff. The tech guys at airmar emailed me a sketch of what color wires had to be connected to what color wires to make it all work. The only thing I lost in the conversion was the water temp wasn't compatible between the garmin and the lawrance units. But the fish finder , depth finder , and speed worked just fine.
