For Sale: ST50 Speed & Depth Display Heads, Airmar Transducers

[KestrelBuck]

My speedo was not displaying so I bought, on this forum, an ST60 Tridata. Therefore, I now have for sale

1. Autohelm (now Raymarine) ST50 depth display head. There are three pig tails on the back. Two are used for connecting to other Autohelm/Raymarine devices. These are three pin connections with the old style barrel connectors. The transducer pigtail has blue, black and bare leads. This unit was working fine when I replaced it. $50 plus shipping.

2. Autohelm (now Raymarine) ST50 speed display head. It is this unit that motivated me to move up to the ST60 tridata. The screen on this unit is so weak that one must sit in just the right place to read it. There are three pig tails: two for seatalk connections and one for the transducer. The transducer pigtail has red, yellow and bare leads. Free plus shipping. Yours if you think you can get some life out of the display.

3. For ST60 system: one ~14.5" Seatalk connector for joining adjacent display heads. The part number is 4001-138-A. The plug on each end is female for three prongs. $20 plus shipping.

4. Airmar p19 depth transducer P/N 31-188-4-02 (&1158). This came with the ST60 I bought, but I don't need it. The diameter of the threaded barrel that screws into the thru-hull is 2". If you don't already have the threaded thru-hull then you will have to buy it. The three leads are blue, black and bare. The wire lead is ~42 feet. There is no connector on the end. $50 plus shipping.

5. Airmar speed and temperature transducer, ST800-P120-RETR, p/n 31-487-1-02 (&1158). This also came with the ST60 I bought, but I don't need it. The five leads are red, white, bare, green and brown. The tiny female spade connectors that fit the ST60 pins are intact. About ~40 feet of wire. The diameter of the sensor that goes through the hull is 1 3/16" (30 mm). You will need to buy the airmar thru-hull fitting in order to use this retractable unit. $50 plus shipping.

The manuals for items 1 and 2 are easily found on the WWW.

Items 1 and 2, the display heads have sold. The expensive little connector that allows two Raymarine instruments to talk to one another is still for sale. The transducers, items 4 and 5, are still available. These are great prices; they are usually $200+ new.

Is the p19 plastic or brass?

[KestrelBuck]

By P19 I assume that you are interested in the depth transducer. It is plastic. The speed/temp transducer is also plastic.

Iam interested in the ST50 head

[KestrelBuck]

To repeat the above post, the ST50 display heads have been sold. Only the newish airmar transducers are available

I would be interested in the st50 depth display and transducer. Will you ship international (currently in Spain) and what are payment options?

Thanks

Hi Jack

The display heads have both been sold. The depth and the speed/temp transducers are still available.

The depth transducer is $50.

The only payment option is PayPal in US dollars. Sorry to be so provincial, but this is the least troublesome and least costly method for me.

I believe that it can go United States Postal Service for less than $20. It would take 6-10 days.
