Can anyone tell me if this item (hunter number) 160100 Airmar number ST800/P120 speed/temp transducer is comparable to the ST50+ instrument? ( this is the original Hunter meter)
Also, is it nmea0183 /nmea2000 compatible. The enclosed paper with the unit does not state this info.

ST800 ST850 Thru-Hull Speed & Temperature Smart™ Sensors Features • Speed and temperature • NMEA 2000® or Analog output options • Retractable plastic, bronze, or stainless steel housings with valve sleeve • ST800—Retrofits into Airmar P120 and B120 housings • ST850—Retrofits into Airmar P17 and B17 housings • 6 m (20’) NMEA 2000 cable, 9 m (30’) Analog cable • Devicenet connector or NMEA 2000 version • Speed Range: 2 knots to 45 knots (2 MPH to 52 MPH) The Smart Alternative! Airmar’s New ST800 and ST850 Smart™ Sensors feature embedded micro-electronics. Speed and temperature signals are processed inside the sensor and can be displayed on any radar, chart plotter, or device that accepts NMEA 2000® data. Minimize Your Drag The ST850 is Airmar’s standard, thru-hull, speed and temperature sensor. The plastic, bronze, and stainless steel outer housing options are available to meet all hull requirements. These low-profile housings are nearly flush and minimize drag with only 5 mm (3/16”) extending outside the hull. Eliminate Turbulence The plastic P217 and bronze B119 countersunk flush outer housings are easy-to-install. The plastic P314 and bronze B21 outer housing options have a traditional beveled-edge for flush mounting. Flush-mount housings eliminate turbulence for accurate readings at high-speeds. They are the optimal choice for installation in racing sailboats and high-speed powerboats

Thanks John, read so many posts and website, missed that info. Maybe you have information about the best approach to connect the existing sea talk instruments to the new Garmin 7410 combo?
Garmin said-:
You will need to use a converter to bridge between your SeaTalk and NMEA2000 networks. I'm afraid that Garmin do not supply such devices.

Presently I have instruments from Autohelm/Raymarine & Airmar on seatalk that I would like to connect to the new Garmin 7410 chart plotter On nmea2000 They are :- ST50 plus depth ST50 plus wind ST6002 raymarine smart pilot Airmar ST800 speed & temp sensor( comparable as mentioned) What unit do I need to convert to nmea2000? Or talk to the Garmin?

Biggest complaint I hear about Garmin devices is they like to keep things proprietary. I know of no existing solution.

I have my system set up so that all St50 information is available on my Garmin Chart Plotter. Attached is how I did it.
It may give you some ideas.

Perfect, just what I needed. Thank you.
There is no reason to have the Auto pilot connected to the nmea2000 backbone, correct?
Just to be sure, if you have a already powered Nmea2000 backbone, plugging in the seperate power cable for the Garmin is not required? Is That correct? Just the Nmea2000 connection.
I don't have a lawyer with me to translate the data sheet!

The ST50 instruments are powered from the ST4000 through the SeaTalk network. (At least on mine) You don't want to power the ST50 instruments from the St4000 and Nmea2000 backbone at the same time.
I could have modified the cable that connected the ST50 instruments to the St4000. Modifying that cable would mean cutting the red power lead in that cable. I may still do that.

The Garmin will still need its own main power connection.
The Nmea2000 backbone requires its own power connection
Good Luck
